Composition of standard units:
UNIT FRAME
Self supporting frame constructed from galvanized sheet steel with polyester powder colour RAL 5014 paint
baked at 180°C to provide a durable weatherproof finish. Threaded fasteners in stainless steel. Painted steel
mesh guard supplied as standard, to protect the condenser coil against impact.
COMPRESSORS
Direct drive semi-hermetic screw compressors with continuous capacity step control from 30% to 100%, to
maximize the unit performances in all working conditions. Start and shut off of unit at 12% of capacity.
Crankcase heater and lubrication through pressure difference between suction and discharge pressure. Independent
refrigerant circuits.
Electronic motor protection via thermal sensors embedded in the windings and in the discharge pipe. Star-Delta
start.
CONDENSER
Composed of a high efficiency coil manufactured from copper tubes and aluminium fins. The V shaped condensing
coils result in a reduction of overall unit dimensions and an increase in the coil surface area leaving a space for the
refrigerant circuit and hydraulic circuit components, if present.
Units with two compressors have autonomously operating condensing sections of the two circuits.
CONDENSER FANS
Axial fans, with sickle shaped blades and special bell mouth designed to reduce noise, directly coupled to a three
phase 6 pole motor with internal Klixon overload protection. Motor protection category is IP 54. The fan is
equipped with a safety grille.
EVAPORATOR

5 POSITIONING
Read the following points carefully when choosing the most suitable site for the unit and its connections:
- dimensions and connection point of hydraulic pipelines;
- location of the electrical power connection point;
- accessibility for maintenance and repair work;
- loading capacity and compactness of the supporting surface;
- ventilation of air-cooled condenser;
- orientation and exposure to sunlight; as far as possible the condenser coil should not be exposed to direct
sunlight;
- direction of prevailing winds: do not position the unit in such a way that prevailing winds can cause air recirculation
at the condenser coil;
- type of support surface: to limit the risk of overheating, do not install the unit on a dark coloured surface (e.g.
bitumen roofing membranes and compounds);
- possible sound reverberation.
All models in the KAPPA V ECHOS series are designed for exterior installation: to avoid the risk of air recirculation
units must not be covered by a shelter roof or located under trees (even if the unit is only partially covered).
It is advisable to make a supporting plinth, perfectly levelled and horizontal, of dimensions commensurate with
the footprint of the unit. This precaution is of the greatest importance if the unit is to be located on unstable
ground. Picture 2 shows a typical supporting plinth structure.
15-20 cm
The floor slab should be:
Figure 2
Plinth slab
- made with a proper foundation raised 15-20 cm above ground level,
- with a cork underlay sealed around the perimeter,
- flat, horizontal and capable of supporting 150% of the unit’s operating weight.
- at least 30 cm longer and wider than the unit.
The unit transmits a low level of vibration to the supporting structure: it is recommended that a layer of rigid
rubber sheeting is placed between the base of the unit and the supporting surface.
If a higher level of vibration damping is required, use anti-vibration mounts (contact Bluebox for details).
When installing on roofs or intermediate floors, units and piping must be isolated from walls and ceilings.
The units should not be installed next to offices, bedrooms, or other areas where low noise levels are a necessity.
To avoid excess sound reverberation do not install the units in narrow or confined spaces.

6. INSTALLATION
6.1 INSTALLATION CLEARANCES
It is important that an adequate air volume is available at the intake and exhaust sides of the condenser coil. It is
essential to avoid air recirculation between the intake and exhaust sides to prevent a reduction of the rated
performance levels and unit operating problems or a possible stop of normal unit operation. The minimum
clearances required for satisfactory operation of the unit is as follows (refer to figure 3):
- hydraulic connection sides: 1.5 metre.
- top: no impediments that obstruct the air discharge.
- electrical panel side: 1,8 meters (see dimensional drawings)
- hydraulic connection sides: 1.5 metre for pipe run location.
(*) It is recommended that sufficient space is allowed for plate heat exchanger withdrawal.
High walls near the machine may interfere with correct functioning. When units are side by side the minimum
distance between them should be 3 metres (see figure 3).
3 m min.
0.75 m (*) 1.8 m
6.2 ANTI-VIBRATION ISOLATORS (option)
1.5 m
Figure 3
It is recommended that the unit is installed on rubber or spring anti-vibration mountings, supplied as an option, to
reduce vibrations transmitted to the building structure. It is advisable to use rubber isolators for units installed in
the basement, or ground floors in contact with the earth, and spring isolators for units installed on intermediate
floors.
6.2.1 Rubber Anti-Vibration Isolators
The anti-vibration isolators must be installed before the unit is
positioned. Ensure that during lifting the unit is firmly secured with
straps.
Rubber isolators are made of an upper metallic bell with a fixing screw to the base-frame of the unit. The isolator
is fixed at the foundation via 2 holes on the flange. On the flange there is a number (45, 60, 70 ShA) which
identifies the hardness of the rubber isolator. The dimensional drawing, enclosed in the machine, shows the unit
footprint with the position and weight of each isolator.

6.3 WATER PIPING CONNECTIONS
Figure 5
Unit water pipework must be installed in accordance with national and local regulation and codes.
Follow the recommendations below when designing the water piping circuit (refer to the diagrams included in this
manual).
- Piping should be connected to the unit with flexible joints, to avoid vibration transmission and allow for thermal
expansion (the same procedure should be adopted for the circulating pumps).
The following devices should be located on the piping system:
- Isolating/regulating valves, temperature gauges or thermometer pockets, pressure gauges or binder points
required for servicing operations.
- Serviceable mesh strainer, with a filtration level no larger than 1mm, located on the unit inlet to prevent debris
from entering the heat exchangers.
- Vent valves, to be installed in the upper parts of the circuit, for air bleeding.
- Expansion device with accessories for circuit pressurisation, water thermal expansion compensation and system
filling.
- Unload valve and if necessary drainage tank for circuit emptying during maintenance and seasonal stop.

6.4 EVAPORATOR WATER PIPE CONNECTIONS
The water inlet and outlet must be connected in the positions indicated
as labelled on the unit.
If incorrectly connected the antifreeze thermostat will not operate and the evaporator may freeze.
A constant water flow to the evaporator must be guaranteed at all
operating conditions to prevent liquid refrigerant from entering the
compressor and causing irreparable damage.
Compressors start and stop often due to changes in cooling demand. In hydraulic circuits with low water volume,
where the thermal inertia action is low, it is advisable to verify that the water volume equals or exceeds the
following ratio:
24 ∙ Q COMPTOT
M>= ---------------------
N
where:
M = system water content [kg]
QCOMPTOT = unit cooling capacity [kW]
N = number of capacity steps
EVAPORATOR WATER
If the water volume does not reach the value given by the formula, it is advisable to provide the circuit with a
storage vessel to increase the volume (tank + circuit) to match the result of the formula.
The chilled water piping and storage vessel must be insulated to prevent condensation on the pipe surfaces and
to avoid circuit performance losses.
It is mandatory to install a flow switch (supplied with the unit) on the
evaporator water outlet connection identified by the following decal:
EVAPORATOR WATER
It is compulsory to install a metallic filter, on the water inlet piping. If
a filter is not installed the warranty will be terminated immediately.
Blue Box 27

We strongly recommend installing a pressure relief valve on the
hydraulic circuit (standard supply on version ST). In the event of
serious system breakdown or emergency (e.g. fire), the system will
be depressurised via the relief valve thus forestalling possible pipe
bursts. Always connect the relief valve outlet to a pipe of diameter
no smaller than the valve opening, and route it to a location in which
persons are protected from the jet of expelled water.
6.5 WATER FLOW SWITCH INSTALLATION INSTRUCTIONS
- Clean the pipeline system into which the flow switch is to be fitted and remove any magnetic particles, such as
welding residues. To prevent turbulent flow there must be straight pipework, equal to 5 times the diameter of
the pipe, either side of the flow switch.
- Connect the “T” shaped metallic manifold (on which the flow switch is mounted) into the evaporator male
threaded water outlet labelled with:
To avoid leakage, seal the connection with teflon. The flow switch must be installed on the evaporator outlet. On
units with more than one evaporator, the flow switch will be assembled on one evaporator only.
Make the electrical
connections on the
unit’s terminal board
Caution: When making hydraulic connections never use naked flames
close to or inside the unit.

- The flow switch must be tightened on the “T” shaped metallic manifold by the plastic knurled union nut. Check
that the arrow located on the upper side is pointing in the direction of flow.Be sure to fit the O-ring seal, through
the brass manifold and the plastic ring nut. The O-ring seal is supplied in a plastic cover to protect the flow
switch shaft.
- Connect the hydraulic circuit at the other end of “T” manifold. Connect the flow switch cable to terminals 1-14
in the terminal box, as indicated on the electrical drawing.
- The flow switch can be removed by screwing out the plastic knurled union nut. In order to reassemble it ensure
that the O-ring seal is positioned in the proper location. (See figure7).

6.7 HEAT RECOVERY EXCHANGER HYDRAULIC CONNECTIONS (OPTIONAL)
For all units equipped with a recovery condenser, the relative hydraulic circuit connections are male threaded
steel pipes (the diameter depends on the unit's size)
The units are equipped with a probe that monitors the temperature of the water returning from the system. The
microprocessor controller enables recovery when necessary, disconnecting the fans, and restarting regular operation
once the water has reached the desired temperature.
If faults occur on the recovery condenser the microprocessor controller restarts the fans.
The calibration values of the thermostat and pressure switches are given in the relevant controller instruction
manual.
For units equipped with a recovery condenser:
The water inlet and outlet must be connected to the recovery circuit
in the positions indicated as labelled on the unit.

6.9 WATER FLOW RATE TO EVAPORATOR
The nominal water flow rate is based on a 5 °C temperature difference between inlet and outlet in relation to the
supplied cooling capacity.
The maximum permissible flow rate is that which results in a temperature difference of 4 °C: higher flow rates will
lead to excessive pressure drops and could damage the evaporator.
The minimum permissible flow rate is that which results in a temperature difference of 7 °C or a pressure drop of
no less than 10 kPa: lower flow rates will lead to excessively low evaporation temperatures with consequent
tripping of safety devices and shutdown of the unit.
6.10 CHILLED WATER TEMPERATURE (summer cycle)
The minimum evaporator leaving water temperature is 6 °C; for lower water temperatures at the evaporator
outlet refer to section 6.14.
The maximum water temperature at the evaporator inlet is 20 °C. In the case of higher temperatures specific
solutions are necessary (dual circuits, three-way valves, by-pass, storage tanks): consult the Bluebox Engineering
Department to discuss the most suitable solution for your application.
6.11 HOT WATER TEMPERATURE (winter cycle)
The minimum water temperature at the condenser inlet, once the system is operating in steady state conditions,
must not be lower than 28 °C: lower values could result in operating anomalies of the compressor with the
consequent risk of compressor breakdown.
The maximum water temperature at the condenser outlet must not be higher than 47 °C. In the event of higher
temperatures the safety devices will trip causing the unit to shut down.
6.12 AMBIENT AIR TEMPERATURE
The units are designed and built to operate with ambient air temperatures within the limits shown on the operating
limits diagrams. Contact Bluebox if the unit is required to operate at different ambient temperatures.
It should be noted that the performance of heat pump units decreases significantly at lower ambient temperatures.
(below 0 °C).
The units can be optionally equipped with an electric element for heating the evaporator. The heater cuts in,
when the machine is switched off, if the water temperature in the evaporator falls below the freeze protection
calibration temperature.
6.13 FAN SPEED CONTROL (optional)
If the unit is required to operate at ambient air temperatures less than 15 °C a fan speed controller must be
included. With fan speed control the unit can function correctly, at low ambient temperatures, by reducing the air
flow supplied to the condenser so that it operates within acceptable parameters.
This device can also be used to reduce unit sound levels as the ambient ait temperature reduces (for instance
during the night).
This control is calibrated and factory tested.
Warning: speed control calibration settings must not be altered. If it
proves necessary to alter speed calibration settings, this task must
be entrusted to a skilled engineer, who should refer to the attached
instruction sheet.
Blue Box 32

6.14 OPERATION WITH LOW TEMPERATURE CHILLED WATER AT EVAPORATOR
With temperatures lower than 6 °C, the hydraulic circuit should be filled with a suitable water and antifreeze
solution. In such cases the service thermostat and the freeze protection thermostat must be reset:
These calibrations are normally factory set.
Units from the normal production range are not designed to operate
with chilled water temperatures lower than 6 °C, at the evaporator
outlet. To operate outside this limit the unit may require structural
modifications. If this is necessary contact Bluebox.
The ethylene glycol percentage must be selected in relation to the required chilled water temperature.

6.15 ELECTRICAL CONNECTIONS
6.15.1 GENERAL
Electrical connections must be made in accordance with the information given on the electrical drawing attached
to the unit and in compliance with the applicable local regulations.
An Earth (ground) connection is compulsory. The installer must connect the earth cable with a dedicated terminal
on the earth bar in the electrical board (refer to the illustration on the following page) labelled PE.
It must be verified that the electrical supply corresponds to the unit electrical nominal data (tension, phases,
frequency) indicated on the label on the front panel of the unit.
Line voltage fluctuations must not be more than ±5% of the nominal value, while the voltage unbalance between
one phase and another must not exceed 2%. If these tolerances are not possible contact Blue Box to provide the
necessary devices.
Check that the line is connected with the correct phase sequence.
The cable inlet point is created by drilling a hole in the side or base of the electrical enclosure, depending on the
model.
The control circuit is derived from the power supply through a transformer located inside the electrical panel.
The control circuit is protected by fuses.
6.15.2 Power supply to crankcase heaters
Electrical cable anchorage: anchor the electrical power cables with
fixing systems able to withstand pulling and torsional stress.
Before any operation on the electrical section, be sure that the electric
supply is disconnected.
Power cable and line protection must be sized according to the
specification indicated on the wiring diagram and the documents
supplied with the unit.
The crankcase heaters must be connected at least 12 hours before
starting the unit; the heaters are automatically connected when the
main disconnect switch is set to the ON position.
The electrical supply must be within the limits shown. If this is not the
case the warranty will be terminated immediately.
1) Close the main disconnect switch by turning it from position “0” to position “1”
2) Check that the word “OFF” is shown on the display
3) Ensure that the unit is in “OFF” status and that the external enabling contact is open
4) After a few moments, if the phase sequence is incorrect the alarm “INCORRECT PHASE SEQUENCE” will be
displayed. In this case invert the connections of two of the power line phase wires.
5) Leave the unit in this condition for at least 12 hours to allow the crankcase heaters to perform their function
Blue Box 34

6.15.3 Potential free contacts
The following potential free contacts are available:
- 1 potential free contact for general alarm (terminals 100 - 101 - 102)
- 1 potential free contact for each compressor (option)
- 1 contact for each pair of fans (option)
- 1 contact for each pump (option - ST models)
6.15.4 Circulating pump electrical connections
The external interlocks of unit must close for the unit to operate. The normally open external water circulating
pump contactor terminals must be wired in series with terminals 1 and 2, on the unit control panel, to ensure that
the chiller can only start after the pump is in operation.
In ST units external enabling contacts 1-2 must be jumpered (unless they are required for system functions).
6.15.5 Microprocessor controllers
Chillers and heat pumps KAPPA V ECHOS are equipped with the pCO 2 microprocessor controller.
The pCO 2 electronic microprocessor controller with the DBBB0*P20Z program is designed to manage chiller and
heat pump units, with control of 2 compressors having 2 capacity steps each.
The program configuretion manages the total control of the air-cooled unit with plate exchangers including
compressor start/stop times, safety devices and other auxiliary functions such as condensation control in cooling
mode, evaporation control in heat pump mode, free-cooling, heat recovery and other functions described later in
this manual.
The necessary hardware is optimised to obtain the maximum advantage from the available inputs and outputs;
the connection between various circuit boards and the user interface terminal is achieved via the pLANE using the
dedicated RS485 serial connector for network connections.
Each unit can also be connected to remote supervision and/or telediagnostics systems by means of an RS485
serial line.
Detailed information on the operation of the above systems is provided in the specific controller manual supplied
with the unit.
6.15.6 RS485 serial interface (optional)
Turn on the pump before the unit starts and stop it after the unit has
stopped (recommended time delay: 60 sec.).
All KAPPA V ECHOS units can be equipped with a serial interface board for supervision or
remote diagnostics functions by means of a computer.
The serial interface board plugs into a dedicated slot on the connection board.
Connection to the supervision or remote diagnostics serial line is executed in compliance with standard RS485
and is achieved by means of the serial interface boards.
When the serial interface board is inserted the following communications protocols are available: Carel and
Modbus. If a connection is to be made with networks that utilise the LonWorks protocol, a dedicated serial
Echelon board must be installed. In this case, a conversion gateway is not required.

7. START-UP
7.1 PRELIMINARY CHECKS
- Check that the electrical connections have been made correctly, and that all terminals are well tightened.
- Check that the voltage on the RST terminals is 400 V ± 5% (or the unit’s rated value, in the event of units
supplied to run on non-standard power supplies). If the mains voltage is subject to frequent fluctuations, consult
our Engineering Department to discuss the necessary protection systems.
- Check that the display shows the gas pressure in the refrigerant circuit (4-compressor models only).
- Inspect the unit for refrigerant leaks using a leak detector if necessary.
- Check that the crankcase heaters are correctly supplied with power.
7.2 OPERATING DESCRIPTION
7.2.1 Introduction
The microprocessor control regulates the water temperature of the evaporator maintaining it at the set-point
value acting on the compressors management.
To provide part load cooling capacity of the compressors, the microprocessor can control two capacity steps for
each compressor.
As well as the compressors the controller manages the operation of other components of the chiller such as the
pumps (ST version) and fans, with relative operating times and alarms, and “ancillary” functions such as condensation
control, etc., as described below.
Almost all the parameters referred to below (set-points, differentials, calibration, delays...) can be programmed
by means of the various menus. Refer to the specific manual for the pCO 2 controller.
7.2.2 Unit in stand-by mode
Significant leakage of R407C refrigerant in the gaseous state will alter
the percentages of the remaining mixture with consequent fall-off of
performance.
The heaters must be connected at least 12 hours before starting the
unit; the heaters are automatically connected when the main
disconnect switch is set to the ON position.
- Verify that heaters are working correctly: after the warm up period the crankcase must be warm to the touch
and must have at least a temperature 10 - 15 °C higher than ambient temperature.
- Check that all hydraulic connections are correctly installed and all indications on unit labels are observed.
- Check that the hydraulic system has been vent to eliminate any air remaining; charge it gradually and open the
vent devices on the upper part, provided at the care of the installer together with an expansion tank of a proper
size.
The unit is in stand-by mode when it is supplied with power but not actually enabled to operate.
In this condition the display shows the values of the various machine parameters, but compressor is inhibited.
When in stand-by mode the unit can be powered on.
Blue Box 40

Power-on is obtained by pressing the “ON-OFF” button of the microprocessor control or via serial or an external
interlock.
7.2.3 Enabling the unit
Start-up of the unit from stand-by mode can be achieved after closing the external enabling contact, by pressing
the “ON/OFF” button, or by means of a signal on the serial line.
Activation of the controller outputs that manage the various sections of the chiller is executed in strict compliance
with the operating times. If the “ON” button is pressed before the external interlocks are closed, the display
indicates which of the external interlocks is not yet enabled.
Operation of the pump has priority to the compressors, which can start only after the pump is running.
7.2.4 Pump management (ST units only)
If system pump control is included switching on the unit will automatically enable the pump.
If there are two pumps (run and stand-by) they will be activated alternately when the programmed operating time
limit for each pump has elapsed.
When the pumps are switched over both pumps will run in tandem, for a few seconds, to ensure a constant flow
of water in the system circuit.
When the unit is switched from active status to stand-by, if performed by opening an external permissive, the
currently active pump of the ST unit will be stopped with a delay interval, after the disconnection of the last
compressor in operation, making it possible to exploit the thermal inertia of the system.
7.2.5 Compressor start-up
The controller allows the compressors to be started if the flow switch input is closed within the compressor startup
delay time interval. If the flow switch input opens, after the compressor has started, the trip is retarded if it
occurs within the time programmed for the compressor stop.
If the unit trips due to the opening of the flow switch input, the relative alarm is displayed.
Starting and stopping of the compressors and capacity step control is managed by the controller in accordance
with the building cooling demands.
7.2.6 Chiller mode operation
In chiller operation, the controller lowers the water temperature value, maintaining it as close as possible to the
programmed set-point.
In the standard version, in which the control acts on the evaporator entering water, the management of compressor
operation and capacity steps is linked to the difference between the entering water temperature and the programmed
set-point.
7.2.7 Heat pump mode operation
In heat pump operation, the controller increases the water temperature value, maintaining it as close as possible
to the programmed set-point.
Management of compressor operation is performed in the same way as already illustrated for chiller mode
operation.
7.2.8 Evaporator low temperature chilled water protection
If the evaporator leaving water temperature is lower than the limit value programmed in the low temperature
chilled water protection set-point, the controller will stop all the compressors and activate the low temperature
water alarm.
This alarm must be reset manually and the compressor restarted only when the evaporator leaving water temperature
is equal to or higher than the alarm trip value, increased by the low temperature water differential.
Blue Box 41

The low temperature water alarm will automatically shut off the entire unit.
The low temperature water alarm can only be activated when the unit is switched on (in stand-by conditions the
freeze alarm is not operational).
7.2.9 Evaporator anti-freeze protection electric heater (optional)
In conditions that lead to tripping the freeze alarm, the controller energises the heater.
The heater remains powered for the entire time that the conditions for the freeze alarm continue.
Unlike the low water temperature alarm, which is enabled only when the unit is powered on, the anti-freeze
heater can be energised when the machine is on stand-by.
7.2.10 Compressor operation
When the unit is running correctly and no general alarms are present, the microprocessor controller starts the
compressors in accordance with the water temperature reading.
Compressor starts are staggered in accordance with preset delay intervals, thus avoiding excess input current
surges.
Before starting a compressor, the microprocessor checks the value of the delivery pressure by means of the
relevant transducer, the status of the high pressure switch and the compressor motor windings temperature by
checking the thermal protection.
When the compressor has been started, tripping of any of the safety devices will cause the compressor to stop
immediately and an alarm will be displayed.
While the compressor is running, discharge pressure and suction pressure are monitored constantly by means of
the relevant sensors.
On unit start-up the first compressor is started with a delay, set on the microprocessor controller, after the start of
the hydraulic system circulating pump.
Once started, each compressor must run for a minimum operating period, unless a critical alarm should trip in the
meantime.
The critical alarms which can stop the compressor during the minimum operating time are the high pressure
alarm and the compressor thermal cut-out alarm. Once stopped each compressor can be restarted only after a
minimum idle time or after a minimum time interval between two consecutive starts has elapsed.
The consecutive starting of two compressors or the consecutive starting of one compressor, is executed with
minimum delay intervals equal to the capacity step activation time.
Stopping compressors is also performed with a minimum programmed delay interval.
7.2.11 Compressors and capacity steps management
Start-up of the compressors is automatic when the reference water temperature changes with respect to the
programmed set-point.
Normally the reference water temperature is the value detected at the chiller leaving water.
The starting procedure as cooling demand increases is as follows:
- the first step of the first compressor is energised, then the first step of the second compressor, then the first
compressor operates at full load and finally the second compressor operates at full load.
As the cooling demand reduces, the capacity steps are unloaded in reverse to the load procedure: all compressors
capacity steps reduced and the compressors are stopped.
Shutdown and start-up of each compressor are always carried out at the minimum of the compressor cooling
capacity.
7.2.12 High and low pressure alarms
Discharge pressure (high pressure) and suction pressure (low pressure) are managed by the microprocessor controller
through the relevant sensors.
When a compressor is running, the controller checks that:
- Discharge pressure is always lower than the safety value set for cooling or heating mode operation.
- The suction pressure is always higher than the safety value set for operation in cooling or heating mode.
Blue Box 42

7.2.13 Low ambient temperature kit (option - condensing control with fan speed
regulator)
As the ambient air temperature decreases the necessary condensing pressure for correct operation of the chiller
cycle is maintained, within the machine operating range, by adjusting the cooling air-flow through the condenser.
Condensing pressure control is only active when the machine is operating in chiller mode.
When the unit is operating in heat pump mode this function is inhibited and the fans are forced to their maximum
speed.
The controller checks the condensing pressure and adjusts fan speed on the basis of the circuit with the highest
pressure reading. The speed regulator adjusts fan speed with a phase control system that minimises problems
related to electromagnetic compatibility.
Speed control is available over a 20-100% range. At the time of start-up the fans always run at 40% nominal
speed.
7.2.14 Changeover from chiller to heat pump and vice versa
The changeover from chiller to heat pump and back can be performed at any time, either by means of an
external signal on a digital input, from the keypad, or via the serial line. The operating mode changeover must be
only seasonal and only with the unit off.
After a mode changeover, the controller re-starts the unit in the new mode with a factory set minimum delay
time.
Blue Box 43

7.2.15 Defrosting (heat pump units only)
During winter heat pump mode operation the finned coil of the air cooled condenser functions as an evaporator,
cooling and dehumidifying ambient air.
During heat pump operation, the evaporation pressure is monitored to prevent it from falling below a preset
value. The evaporation control is active only during heating mode operation.
Depending on the ambient air temperature and humidity conditions, condensate or frost will tend to form,
consequently obstructing the free passage of air and causing thermal insulation. The frost that builds up on the
coil obstructs the passage of air and reduces the available heat exchange surface area (and thus the thermal
efficiency) and can damage the heat exchanger.
Defrosting is the procedure that eliminates the ice that has formed on the evaporator coil during heat pump mode
operation of an air/water unit.
Defrosting is performed simultaneously for the entire unit.
All heat pump versions are equipped with a control that activates an automatic coil defrost cycle when necessary.
After starting however, the first defrost cycle will be started after a preset minimum operating time to allow the
formation of sufficient thermal inertia to allow the cycle to be completed successfully.
Defrost cycle activation is based on the detection of a low suction pressure value due to insufficient heat exchange
between the evaporator and the air due to the formation of a layer of ice, which exerts a thermal insulation
effect. For a defrost cycle to be able to start a suction pressure of at least one of the currently operating compressors
must remain below the pressure set for the defrost cycle trip signal for a preset time interval.
Before starting to defrost the coils, all the compressors are started, after which the unit reverses its operation from
heat pump to chiller mode.
When the cycle is reversed the fans stop and the compressors force hot gas into the coil.
A pressure switch on the high pressure circuit maintains the discharge gas pressure below the defrost end value.
To maintain the pressure lower than the defrost end pressure the pressure switch activates the fans.
To reduce the air flow and obtain more efficient heating of the outer part of the coil, the pressure switch signal
causes the fans to rotate in reverse.
When the defrost end temperature is reached, as measured by a thermostat with a probe located in the lower
part of the coil, the pressure switch allows the discharge pressure to reach the defrost end pressure.
When the defrost end pressure has been reached, the controller reverses the unit from chiller mode to heat pump
mode, thereby terminating the defrost procedure.
Even though in certain conditions the surface temperature of the coil and the condensation pressure fail to reach
the defrost values within the preset time limit, the defrost cycle is forcibly terminated as though the defrost end
signal were present. The controller restarts the fans, and when the pressure lowers again to the preset value, it
reverses the unit’s operating mode again.
If the defrost cycle is forcibly interrupted, with the timeout signal, a message is displayed on the controller,
although no controller functions are activated.
The defrost timeout alarm is automatically cleared from the active alarms menus when a defrost cycle terminates
normally because the defrost end pressure has been reached. In any event, the alarms historical file will contain
a record of all defrost cycles that were terminated forcibly due to a timeout intervention.
Consecutive defrost cycles must be at least 30 minutes apart. If the forced defrost signal persists, inform the
Service organisation.
7.2.16 Total heat recovery (option)
Heat recovery is the function where all the energy that would normally be rejected to the air cooled condenser is
recovered at a refrigerant to water condenser installed in series with the air-cooled condenser.
The heat recovery process is managed by the microprocessor controller.
During energy recovery the fans are stopped and the condensing coil is by-passed via solenoid valves connected
downstream of the thermostat valve. The machine is equipped with a liquid receiver.
Heat recovery can only occur when the water temperature at the recovery exchanger inlet is lower than the
recovery set-point. Heat recovery is terminated when the temperature increases by the recovery differential
value.
It is mandatory to use a condensing pressure control valve (one for each hydraulic circuit) or three-way valve,
fitted by the installer, to avoid condensation values that are incompatible with operation of the machine.
Blue Box 44

7.2.17 Dual set-point (option)
Operation with a dual set-point is possible only in chiller mode.
With double thermostatic valves and solenoid valves that are automatically switched according to the required
expansion temperature. Two set-point values can be programmed on the microprocessor controller via the keypad
or a digital input. Switching of the thermostatic valves is always automatic, in accordance with the water temperature.
The valves are sized on the basis of the temperature values specified at the time of the order. The machine
operating limits shown in the catalogue are not affected. If the hydraulic circuit contains glycol in sufficient
quantities to eliminate the risk of freezing, the lower limit is extended to a minimum of -5 °C leaving water
temperature.
7.3 STARTING THE UNIT
Fixed protections
- The protections are positioned and fixed in a solid manner.
- Their opening requires the use of specific tools. They do not stay in place without the fixing devices.
It is absolutely forbidden to switch on and start the unit without the
fixed protection devices.
For the start-up procedure refer also to the microprocessor controller manual.
- Close the external enabling contacts
- Press the "ON" button on the microprocessor controller
- If all the controls are enabled the display will show the message "UNIT ON"
After having performed the above procedures the unit will start automatically after a delay of approximately 5
minutes, assuming that the enabling signals of the microprocessor, the flow switches, and the water pumps
continue to be present.
Blue Box 45

If the unit fails to start: do not change internal electrical
connections on penalty of immediate invalidation of the
warranty.
Important: on heat pump versions the operating cycle must be
reversed at the start and end of the season. Frequent switching
from summer to winter mode, and vice versa, should be avoided
at all costs because it can lead to malfunctions and subsequent
breakdown of the compressors.
During idle periods do not disconnect the unit from the power
supply (the compressor crankcase heaters must remain
switched on in these intervals). Disconnect the unit from the
power supply only in the event of prolonged disuse (e.g.
seasonal shutdowns). For temporary shutdown of the unit refer
to the guide lines given in paragraph 7.4.
Blue Box 46

7.4 STOPPING THE UNIT
7.4.1 Temporary stop:
- To stop the unit press the "OFF" button on the front panel.
7.4.2 Seasonal stop:
- Disconnect the power supply
- Drain the system circuit (unless it contains a water/glycol solution)
- When the unit is to be restarted repeat the initial start-up procedure
7.5 EMERGENCY STOP
Figure 12
Warning: do not use the machine main power switch to stop the unit:
this switch must be used to disconnect the electrical supply when no
current is flowing on the circuit, i.e. only when the unit is in OFF status.
Note also that if power is disconnected from the unit, the crankcase
heaters will be switched off with the resulting risk of compressor
damage at the time of restarting.
Emergency stops are obtained by turning the red colour main disconnect switch on the electrical panel to position
0. (figure 13).
Turning the main disconnect switch to position 0, the entire unit is disconnected from the powert.

8 CHECKS DURING OPERATION
8.1 INTRODUCTION
- Check that the water temperature at the evaporator inlet is close to the set-point value of the service thermostat.
- For units equipped with pump units, if the pump runs noisily, close the relative delivery cock until the pump starts
running smoothly again. This situation can occur when system pressure drops deviate significantly from the
pump available pressure.
8.1.1 Checking the refrigerant charge
- After a few hours of unit operation check that the sight glass moisture indicator has a green coloured core. if the
core is yellow, moisture is present in the circuit. In such a situation the circuit must be dehydrated by a qualified
technician.
- Check the sight glass for bubbles. A constant passage of bubbles through the sight glass could indicate that the
refrigerant must be replenished. Occasional bubbles are considered normal.
- A few minutes after the start of the compressors, check that the condensing temperature, equivalent to the
pressure read on the pressure gauge, is approximately 18 °C higher than condenser inlet air temperature. Also
check that the evaporating temperature, equivalent to the pressure read on the pressure gauge, is 5 °C lower
than the evaporator outlet temperature.
- Check that refrigerant liquid superheating is between 5 and 7 °C; to do this:
1) measure the temperature using a contact thermometer placed on the compressor suction pipeline;
2) read the temperature, equivalent to the pressure read on the pressure gauge connected to the compressor
suction side (saturation temperature corresponding to suction pressure); for units charged with R407C
refrigerant, refer to the D.P. (Dew Point) pressure gauge scale.
The difference between the temperatures measured in this manner is equivalent to the superheating value.
- Check that refrigerant subcooling is between 5 and 7 °C; to do this:
1) measure the temperature using a contact thermometer placed on the compressor discharge pipeline;
2) read the temperature, equivalent to the pressure read on the pressure gauge connected to the liquid
connection at the condenser outlet (saturation temperature corresponding to condenser delivery pressure);
for units charged with R407C refrigerant, refer to the B.P. (Bubble Point) pressure gauge scale.
The difference between the temperature values measured in this manner is equivalent to the subcooling value.

10. MAINTENANCE AND PERIODIC CHECKS
10. 1 WARNINGS
10.2 INTRODUCTION
All operations described in this chapter MUST BE PERFORMED
EXCLUSIVELY BY QUALIFIED PERSONNEL.
Make sure that the unit has been disconnected from the power supply
before carrying out any work or accessing internal parts.
The compressor head and discharge pipeline can reach high
temperatures. Always exert caution when working in the vicinity of
the compressor.
Adopt the maximum caution when working in the vicinity of the finned
coils because of the sharp edges of the aluminium fins.
Carry out the following periodic checks to ensure the unit is operating correctly:
CHECK PERIOD
Check that safety and control devices work correctly as previously described monthly
Check that all the terminals within the electric panel and compressor are tight The
sliding terminals of the contactors should be periodically cleaned: if any damage is
found, replace the contactors
monthly
Check the sight glass to verify the refrigerant charge. monthly
Check that there is no oil leakage from the compressor monthly
Check that there is no water leakage in the hydraulic system monthly
If the unit is to be stopped for a long period the hydraulic circuit, including all pipes and seasonal
heat exchangers, should be drained. This is compulsory if the ambient temperature is
expected to fall below the freezing point of the liquid employed.
operation
Check process water levels monthly
Check that the flow switch is operating correctly. monthly
Check that the crankcase heater is operating correctly and there is a power supply. monthly
Clean metallic filters on water piping monthly
Clean the finned coil or the filter coils, if present, by means of compressed air, which
should be directed in the opposite direction to the normal direction of air flow. If the
coil is completely clogged clean with a jet of water.
monthly
Execute a defrost test (heat pump units only) monthly
Check the condition, anchorage, and balancing of fans every 4 months
Check the colour of the sight glass core (green = no moisture, yellow = moisture
present): if it is yellow change the refrigerant filter
every 4 months
Check that the noise level has not increased. every 4 months
Blue Box 50

10.3 REPAIRING THE REFRIGERANT CIRCUIT
If repairs have been made to the refrigerant circuit, perform the following steps:
- leak test;
- vacuum and dehydration of refrigerant circuit;
- refrigerant charge.
10.3.1 Leak test
If the circuit is to be emptied, use the appropriate equipment to collect
the refrigerant.
Charge the refrigerant circuit to a pressure of 15 bar with dry nitrogen gas by means of a cylinder fitted with a
pressure reducer. Check the circuit for leaks with a leak detector. The formation of bubbles or foam indicates the
presence of leaks.
If leaks are found during the test, empty the refrigerant circuit and then repair the point of leakage by welding
with appropriate alloys.
Do not use oxygen instead of nitrogen: explosion hazard.
10.3.2 High vacuum and dehydration of the refrigerant circuit
To generate a high vacuum in the refrigerant circuit use a high vacuum pump able to reach 0.1 mbar of absolute
pressure with a flow rate of 10 m 3 /h. With this type of pump, a single vacuum cycle is normally sufficient to reach
an absolute pressure of 0.1 mbar.
If this type of pump is not available, or in the event that the circuit has been left open for a long period of time,
you are strongly advised to use the triple evacuation method. This procedure is also prescribed in the event of
moisture in the refrigerant circuit.
Connect the vacuum pump to the charge connector.
Proceed as follows:
- Evacuate the circuit to a pressure of at least 34 mbar absolute. Charge the circuit with nitrogen to a relative
pressure of approx. 1 bar.
- Repeat the operation described above.
- Repeat the operation described above for the third time in order to reach the highest degree of vacuum possible.
This procedure should guarantee the elimination of up to 99% of contaminants.
Blue Box 51

10.3.3 Refrigerant charge
- Connect the refrigerant gas cylinder to the male 1/4 SAE charge connector on the liquid line and allow a small
amount of gas to escape in order to purge the connection hose of air.
- The circuit must be charged exclusively with liquid; therefore, if the cylinder is not equipped with a dip pipe it
must be turned upside-down.
10.4 ENVIRONMENTAL CONSIDERATIONS
Units operating with R407C must be charged exclusively with liquid
refrigerant by way of the charge connection on the liquid line.
A unit that was originally factory charged with R407C cannot be
charged with R22 (and vice versa)!
Laws governing the use of substances detrimental to the ozone layer prohibit the dispersal of refrigerant gases in
the environment, obliging users to recover refrigerants at the end of their useful life and consign them to the
dealer or to specific collection centres.
Refrigerant R407C IS mentioned among substances subject to special monitoring regimes established by law, and
as such they are subject to the prescriptions indicated above.
11. TROUBLESHOOTING
Use special care during maintenance work in order to limit the risk of
refrigerant leakage as far as possible.
The following pages contain a list of the most common causes that can result in the shutdown or anomalous
operation of the chiller. Faults are arranged in accordance with easily identifiable symptoms.
In relation to possible corrective action, adopt the maximum attention
in the operations you intend to perform as overconfidence coupled
with insufficient attention due to lack of expertise can lead to serious
accidents. We therefore recommend that Blue Box or other skilled
HVAC engineers are contacted to identify and correct the problem.

12. DECOMMISSIONING THE UNIT
When the unit has reached the end of its useful life and must therefore be removed and replaced, adhere to the
following rules:
- the refrigerant must be recovered by a qualified technician and sent to an authorised collection centre;
- also the compressor lubrication oil must be recovered and sent to a collection centre;
- the structure and components, if unusable, must be stripped down and separated according to the material
type; this is particularly important for copper and aluminium, which are fairly abundant on the machine.
This procedure is designed to assist the work of collection, disposal, and recovery specialists and to reduce the
associated environmental impact.
