WATER CONNECTIONSGENERALPiping must be designed with the least possible number ofbends and head variations. If the pressure chute of theinstallation is above the useful prevalence of the pump, thewater delivery capacity is reduced as well as, as aconsequence, the thermal exchange and the yield.INTERCEPTING VALVESInstall on the input and output of the user parts(exchangers, coils, humidifiers, etc) So that it will bepossible to carry out all the service operations and possiblesubstitutions without emptying the installation.PRESSURE AND TEMPERATURE INDICATORInstall on the input and output of the user parts(exchangers, coils, humidifiers, etc) So that it will bepossible to carry out all the service operations.AUTOMATIC OR MANUAL ESCAPE VALVESInstall the highest points of tubes in a way that the air canescape form the circuit.BLEEDING COCKInstall them at the lowest points of the circuit, so as to allowemptying.LEAKAGE TESTSBefore performing the insulation of the tubes, carry out aleakage test.TUBE INSULATIONAll tubes of water must be insulated so that to avoid theformation of condensation and thermal dispersions alongthe tubes themselves. Verify that the insulation is thevapour coil type. The connections for the air escape and forthe emptying must be out of the insulating thickness toassure the accessibility.CONNECTIONS SUPPORTSThe weight of the hydraulic connections must be supportedin the exterior of the unit so as not to stress the connectionsof user devices (exchangers, coils, humidifiers, etc ) .ANTI-VIBRATION DEVICESIn case of units with anti-vibration devices, it is necessary toassemble elastic joints, even on water connections.RISK OF FREEZEIf the unit and the relevant water connections are subject totemperatures near 0°C:mix the water of the system with glycolprotect the tubes with heating cables under the tubesinsulationempty the system by verifying that:oono taps are closed so they can not trap the water,even after emptyingthere are no low points where the water canstagnate even after emptying; blow if necessaryINSTALLATION EMPTYINGThe refilling of the water present in the installation increasethe oxidation phenomena and lime deposits.If necessary empty only the interested system section andanyway empty or refill the installation if necessary .EXPANSION TANKThe installation must be kept at the right pressure by bothan expansion tank and a combined valve of pressurereduction and discharge; if the components are present onthe unit, they must be installed on the installation. Theexpansion tank must be dimensioned in function of thewater in the installation.MAX. WORKING PRESSURE10,5 bar evaporator16 bar condenserARIES EFFECTS AND AIR BUBBLES CAN PRODUCETHE OVERCOMING AND CAUSE WATER DROPS.EXCHANGER USE SIDEFILTERIt is very important for the water to be free of impurities. If itis not, the efficiency of thermal exchange is diminished. Inworst cases, the exchanger can be irreparably damaged. Ifthe filter is not present on the machine, it must beimmediately installed upstream from the unit, in a positionwhich can be easily reached for cleaning.The filter mesh must be :< 1 mm unit with 1 compressor< 1.5 mm multicompressor unit.FLOW SWITCHThe flow switch must be present as a component of thesystem, so as to ensure shutdown of the unit if water is notcirculating. It must be installed in a straight tract of thetubes, not near the elbows, which can generate harmfulturbulenceUNFREEZABLE LIQUIDSIf the unit is used when the water temperature is lower than+ 4°C, avoid the formation of ice by using unfreezableliquids (ex. Ethilenic Glycol) in the necessary percentage.The use must also be determined for ambient temperaturesnear 0°C .ANTIFREEZE RESISTANCESIf the unit is equipped with antifreeze resistances on theexchanger side (standard or optional according to themodels), verify that they are electrically fed during periodsthat the machine is stopped (night, weekends, long stops)WASHING THE SYSTEMCarefully wash the system by using clean water anddischarge it before connecting the unit.M03Y40D9-01 09/04/10 page 12

In the worst cases, the exchanger can beirreparably damaged. The filter, if not present on-boardthe machine, must be installed immediately upstreamfrom the unit, in a position that is easily accessible forcleaning.FLOW SWITCHSince it is a system component, it must always beincluded, in order to ensure unit shutdown in the event offailure of water circulation. It is to be installed in astraight section of the pipes, and not near curves whichgenerate harmful turbulence.ANTI-FREEZE SOLUTIONSFor use of the unit with ambient temperatures near 0°C,use antifreeze solutions such as ethylene glycol toprevent the formation of ice. Its use is also requiredwhen geothermal probes are used.SYSTEM WASHINGBefore connecting the unit, carefully wash the system by fillingit and emptying it several times with clean water.CUT-OFF VALVEThis allows cut-off of water on the source side whenever thecompressor is not running.It is therefore advisable for systems with disposable water, ifthere is no modulating valve.PR8C1M03Y40D9-01 09/04/10 page 13

REVERSAL ON WATER CIRCUIT - OPTIONThe hydraulic system must be plan to allow the inversion use-evaporator / use-condenser:in cooling modality the use is connected to the outlet water from the evaporatorin heating modality the use is connected to the outlet water from the condenserThe diagram is to be considered merely approximate.

In the hydraulic system the deviation members indicated in the previous scheme are not required.The control system manages as well the heating set point, with the relatedlogics of thermoregulation and security.RECOVERY EXCHANGER (OPTIONAL)The unit can be equipped with exchangers to recover the condensation heat.with 20% recoveryThe customer is responsible for the management of the circulation pump,valves, thermostats, etc.The recovery input water must not be below 25°C, in the event that, wrongfuloperations and breakages of the unit can occur.Water connections must be performed carefully as for the evaporator (filter, circuitwashing, etc).Perform all necessary interventions to avoid the RISK OF FREEZING (tubesinsulation, emptying of circuit, addition of glycol, anti-freeze resistances).Water temperature can reach high temperatures (up to 100°C), therefore:avoid the RISK OF BURNS by adopting the necessary precautions(insulation of tubes, temperature detecting station on water if the sanitaryuse is foreseen, etc.)Install safety valves and specifically dimensioned expansion tanks in thehydraulic circuit.OUTINM03Y40D9-01 09/04/10 page 14

HYDROPACK - OPTIONALOPTIONALThe equipment of refrigerant groups with the Hydropackaccessory allows the supply of the necessary rate/headwith different solutions:HYDROPACK with 1 pumpfor low-power units you can choose the basic solution with1 pump.HYDROPACK with 1 pump + 1 standbyalso for low-power units you can include a second pumpfor complete reliability. If one pump shuts down, the otherone automatically starts up and the unit control signals theshutdown of the pump that is out of order. The microprocessorautomatically balances the hours of operationof both pumpsHYDROPACK with 2 pumpsPer less power units, the standard solution with 2 pumpscan be chosen. If a pump gets blocked, the unit will go onworking till about 80% of the charge. This solution is morereliable than the traditional ones with a single great powerpump.HYDROPACK with 2 pumps + 1 stand-by,2 reserve pump can be foreseen for assuring a totalreliability.So the design water rate is assured (in fact, in the event ofa failure, the reserve pump is automatically activated andthe unit control signals if the broken pump is blocked).HYDROPACK with 3 pumpsfor units of greater power; with the solution of 3 pumpswhich are always activated, the possible blocking of apump always assures the regular working up to 80% ofthe charge (always with the signalization of the blocking).In this case, it is possible, upon request, to supply areserve pump (not connected). The replacement isperformed in few minutes time, thanks to the simpleforeseen connections.The modular pumping system allows for the automaticreduction of the water rate, in case the temperature isabove the operating limit.This device is very useful during starts-up, weekendpauses, and after a long period of inactivity.When the water temperature of the hydronic circuit is veryhigh, possible blocks for overcharging are avoided, as wellas the consequent interventions of specialized personnelfor the assisted start-up.Multi pump hydronic group including:R = shut-off valvesF = steel mesh filter(optional)M = manometersVS = safety valve (6 Bar)P = high efficiency single-structure and single-rotor electricpumpsVR = check valvesPRS = safety pressure switch (avoids pumps operation in case ofwater absence)PHE = evaporator-kit including two blind plugs needed in case ofpump removal for maintenance operationsOPTIONAL1 – 3 pompePHEPRS MRMR FRVRPVSVICTAULIC CONNECTIONS1.

When the unit is on, the ―ON‖ message isdisplayed; when the unit is off, the ―OFF‖ message is displayed.It is also possible to access the different menus when the unit is in the ―OFF‖ mode.It is possible to check the ON/OFF condition at a distance, using a remote device (see the ELECTRICAL CONNECTIONSchapter).THERMOREGULATIONThe thermal regulation is based on the INLET temperature.The unit is set for a specific TOTAL DIFFERENCE between the inlet and outlet water temperatures.Usually the designed difference is 5°C, in the event that a different value is foreseen, the 17 and 18 parameters must be setagain by the assistance center.According to the total difference, the system defines the level of difference that each compressor can give : the STEPDIFFERENCE.The regulations tend to gradually insert the compressors when the inlet temperature is over the set-point + the step difference.The compressors are activated one per time at the end of the SCANNING TIME.This time varies according to the gap between the water inlet temperature and the Set-point value. The higher the gap value is(both negative and positive), the shorter the interval among the scanning points will be.The value of the scanning time is displayed at the status 6; when the status 7 has reached the value of the status 6, therequest of operation of the compressor is activated.The counting of the scanning time starts together with the activation of the compressor.The compressor to be activated is chosen to make the shut circuits operate in order to minimize the wear of the entirerefrigerating circuit, as well as the single compressor.At the end of the counting, if the inlet temperature is higher than the step difference, another compressor is inserted.temp.

SET-POINT COMPENSATIONSThe compensations are evolved functions that aim at protecting the compressors and fit as much as possible, the operation ofthe unit to the characteristics of the system and its use.The compensations make the time of the compressors’ operation longer and limit the number of starts-up, to make them delaythe insertion time by adding an offset.The compensation on the DURATION is useful when the water contained in the system is limited.The compensation on the CHARGE is useful when a variable charge is present.Optional components are necessary; the modifications of the parameters performed by the assistance centers have to beperformed to enable and configure. In industrial applications, where a precise control of the temperature is necessary, it ispossible to deactivate the COMPENSATIONS. The Status menu displays the value of the compensations on ext. temp. (status9) and WR (status 10).SET-POINT CORRECTIONSThe correction aim at optimising the energetic efficiency of the unit.To do this, the corrections dynamically modify the set-point according to some variables. For example, in the summertime withvery low external temperatures, therefore with a reduced load, it is possible to obtain the internal comfort even with set-pointshigher that the standard with a consequent higher energetic efficiency.The static set-point can therefore be modified dynamically with two CORRECTIONS based on two factors external to the unit:Correction based on the External temp. / enthalpyCorrection based on the Water reset (4-20 mA signal supplied by the Customer)The correct set-point, to which all corrections have been added or detracted, is called PRESENT set-point and is visible atstatus 2.For further details, see the ELECTRICAL CONNECTIONS chapter.MAINTENANCE SET POINTIt can be used to maintain the installation inside the working limits, even if the unit is deactivated.The MAINTENANCE Set Point checks the water temperature when the unit is put on OFF or Stand-by.To do this, it periodically activates the circulation pump, tests the water temperature and even activates one or morecompressors.

This will make fixing upbreakdowns easier.Take note of the date, type of control (autonomousmaintenance, inspection or fixing up), description of thecontrol, actions taken and so on.SERVICESParts subject to interventionSTRUCTURECheck the condition of the parts making up the structure.Paint so as to eliminate or reduce oxidation at the points in the unit where this problem may occur. Check that the panelling isfastened correctly. Poor fastening may give rise to malfunctions and abnormal noise and vibration.WATER EXCHANGERIt is very important for the exchanger to be able to provide the maximum thermal exchange. Therefore, it is essential for theinner surfaces to be clean of dirt and incrustations.Periodically check the difference between the temperature of the supply water and the condensation temperature. If thedifference is greater than 8°C–10°C it is advisable to clean the exchanger.M03Y40D9-01 09/04/10 page 37

MAINTENANCE INSPECTIONSForesee inspection assistance carried out by authorizedcenters or by qualified personnel.The inspections should be carried out at least:- Every year for only the cooling units- Every six months for the cooling and warmingunitsThe frequency, however, depends on the use: in the eventof frequent use (continuous or very intermittent use, nearthe operating limits, etc) or critical use (service necessary)it is recommended to plan inspections at close intervals.For units equipped with safety valves, follow theManufacturer’s instructions.Verify periodically the cleaning of the safety valves andthat oxidative / corrosive phenomena are not present, inparticular for installations near the sea, in industrial areasor in rooms with a corrosive atmosphere.The inspections to be performed are as follows:verify the power supply tension (when emptied or filled)inspect the electrical board (status of solenoid startercontacts, terminal closings, the status of wiring andrelevant insulations)inspect the absorption of the single electrical loadsverify the cleaning and the efficiency of the exchangersinspect the cleaning of the filters (air/water)verify the leakage from the refrigerating circuitVerify the protection devices (safety valves, pressureswitches, thermostats, etc.), the adjustment systems,the control devices (alarm signalizations, probes,manometers, etc)check the operating parameters of the refrigeratingcircuit (see the following REFRIGERANT TABLES andthe START-UP section)97/23 CE PED DIRECTIVE97/23 CE PED DIRECTIVE gives instructions for installers, users and maintenance technicians as well. Refer to localactuation norms; briefly and as an example, see the following :COMPULSORY VERIFICATION OF THE FIRST INSTALLATION only for units assembled on the installer’s building site(for ex. Condensing circuit + direct expansion unit)CERTIFICATION OF SETTING IN SERVICE for all the unitsPERIODICAL VERIFICATIONS to be executed with the frequency indicated by the Manufacturer (see the MAINTENANCEINSPECTIONS section)PUT AT RESTIf a long period of inactivity is foreseen, for example thewinter for the cooling unit, the following is recommended:to turn the power off in order to avoid electrical risks ordamages by lightning striketo avoid the risk of frosts as shown in the HYDRAULICCONNECTIONS section, and, in particular- to empty or add glycole in the plant sectionssubjected to temperatures below zero- to empty or add glycole in the water heating coils,also in summer- to power antifreeze resistances if presentIf the period of inactivity is particularly long or in the eventof extremely low temperatures, the external fans can beblocked temporarily; therefore, it is recommended toswitch them on every month in order to avoid seizures orelectrical overloads when the unit will be switched on.The restarting of the unit has to be carried out by qualifiedpersonnel, in particular, after the winter break for coolingunits or when seasonal switching should be performed.When restarting, refer to the SWITCHING ON section.Schedule technical assistance in advance to avoidhitches and be able to use the installation whennecessary.M03Y40D9-01 09/04/10 page 38
