- RESIDUAL RISKS -- RESIDUAL RISKS -GENERALThis section lists some of the more common situations which, being beyond the control of the manufacturer, could be asource of risk to persons or property.DEFINITION OF DANGER AREAThe figure below highlights the area in which only authorised personnel may operate.- External danger zone, identified by a precise area around the unit and its vertical projection on the ground in the case ofhanging unit.- Internal danger zone, identified by the area that can be entered only after having intentionally removed the protectingpanels or parts of these.HANDLING- If handling operations are undertaken without adopting all the necessary safety procedures and exercising due care,the unit can fall or topple, causing damage — possibly extremely serious — to persons and/or property, and to the unititself. Ensure the unit is handled and manoeuvred as directed on the packing and in the present manual, and inaccordance with local regulations. In the event of refrigerant gas escaping, refer to the “Safety datasheet” for theparticular refrigerant.INSTALLATION- Incorrect installation of the unit can result in water leaks, accumulation of condensate, escape of refrigerant, electricshocks, fire, as well as irregular operation or damage to the unit itself. Make certain that the installation is carried out onlyby a qualified technician, also that the directions contained in this manual are followed and local statutory regulationsobserved.- In the event of the unit being installed in a site where there is even the slightest risk of inflammable gas escapes andconsequently the possibility of such gases accumulating in area around the unit, the risk of explosion and fire cannot bediscounted. Take every care and precaution when selecting the installation site.- Installation on a structure not able to bear the weight and/or afford a secure anchorage of the equipment may cause theunit to fall and/or topple, resulting in damage to persons or property, or to the unit itself. Make certain that every care andprecaution is taken when positioning and securing the unit.- If the unit is easily accessible to children, unauthorized persons or animals, this is a situation that can give riseaccidents and injuries, perhaps serious. Install the unit in a place where access is allowed only to authorized persons, orinstall barriers or guards preventing unauthorized entry.GENERAL RISKS- A smell of burning, smoke or other indications of serious irregularity could signal the onset of situations liable to causedamage to persons or property or to the unit itself. Isolate the unit from the electrical power supply (red-and-yellowswitch), and contact an authorized service centre so that the source of the problem can be identified and remedied.- Accidental contact with heat exchange coils, compressors, pressure pipelines or other components can result inwounding or burns, or both. Always wear suitable clothing, including protective gloves, when working in the danger area.- Maintenance or repairs carried out by unskilled operatives can result in harm or damage to persons and property, or tothe unit itself. Always contact an authorized service centre.- Failure to close the panels of the unit, or to check that all the fixing screws of the panels are properly tightened, canresult in harm or damage to persons or property, or to the unit itself. Verify periodically that all panels are closed andmade properly secure.- In the event of fire, the temperature of the refrigerant can rise to the point that pressure will exceed safety levels andperhaps cause fluid to be projected. It may also happen that parts of the circuit isolated by closed valves will explode. Donot stand near safety valves, and never leave the valves of the refrigerant circuit closed.ELECTRICAL SYSTEM- If the power line connecting the unit to the a.c. supply is incomplete, or if the connection is made with cables of incorrectcross section and/or with insufficiently rated protective devices, this can result in electric shock, toxicity hazard, damageto the unit or fire. All work on the electrical system should be carried out referring to the wiring diagram and to thedirections given in this manual, and the system itself must be dedicated.6 MSAT-SC M49W40L5

- RESIDUAL RISKS -- Failure to secure the cover enclosing electrical components can lead to the infiltration of dust and water, ultimatelycausing electric shocks, damage to the unit, or fire. Always fasten the cover securely to the unit.- If live metal parts of the unit are not connected properly to the earth system, they can cause electric shock or evendeath by electrocution. Make absolutely certain that the connection to the earth system is made in accordance withcorrect practice.- Contact with live parts rendered accessible internally of the unit when the guards are removed can result in electricshock, burns or death by electrocution. Before exposing these parts, make certain the isolating switch on the power lineto the unit is set to the OFF position and padlocked, and post a warning sign.- Contact with parts that could become live when the unit is started up can result in electric shock, burns or death byelectrocution. When there is no need for circuits to be powered up, set the isolating switch on the power line to the OFFposition, padlock it and post a warning sign.MOVING PARTS- Contact with the fan rotors can cause injury. Before removing the protective grilles or the fans themselves, make certainthe isolating switch on the power line to the unit is set to the OFF position and padlocked, and post a warning sign.- Contact with the fan rotors can cause injury. Before removing the protective grilles or the fans themselves, make certainthe isolating switch on the power line to the unit is set to the OFF position and padlocked, and post a warning sign.REFRIGERANT- In the event of safety valves coming into operation and releasing refrigerant gas, persons in the vicinity can be injuredor suffer toxic effects. Always wear suitable clothing and protective goggles when working in potential hazard areas. Inthe event of refrigerant gas escaping, refer to the “Safety datasheet” for the particular refrigerant.- If an open flame or heat source is brought into contact with the refrigerant, or the pressurized gas circuit shouldoverheat (e.g. during welding operations), this can cause explosion or fire. Do not position any heat source within thehazard area. Maintenance or repair operations involving welding must be carried out with the system emptied ofrefrigerant.WATER SYSTEM- Defects affecting pipelines, connections or valves and other control componentry can result in water being leaked orsprayed from the system, occasioning damage to property or causing short circuits in the unit. Make certain all hydraulicconnections are securely made, following the directions given in the present manual.REFRIGERANT SAFETY CHARTS01 Identifying elements forthe substance02 Information concerningcomposition ofcomponentsProduct name: forane 407CN°SDS 01965/1Supplier: ELF ATOCHEM ITALIAVia G.Murat 17, 20159 Milano tel. 02/668111Chemical nature of the compoundMixture based on:Forane 32(difluoromethane) (N° CAS: 75-10-5)Forane 125 (pentafluoroethan) (N° CAS: 354-33-6)Forane 134a (1.1.1.2 tetrafluoroethan) (N° CAS: 811-97-2)03 Identification of risk Greatest physical and chemical dangers:Thermal decomposition in toxic and corrosive products04 First-aid measures General information:Inhalation: Carry the victim into the open air.

- RECEPTION/POSITIONING -INSPECTION UPON RECEPTION- RECEPTION/POSITIONING -Check on arrival that the unit has not suffered damage during transit and that it is complete in every part as specified inthe order. In the event of visible damage/deficiencies being discovered, make a note immediately on the deliverydocument with the comment: "CONDITIONAL ACCEPTANCE — CLEAR EVIDENCE OF DEFICIENCIES/DAMAGEDURING TRANSIT", then inform both the supplier and the carrier of the details by fax and by registered mail with adviceof receipt not later than 8 days after taking consignment. Notifications sent after 8 days have elapsed will be ignored.STORAGEShelter from: direct sunlight, rain, sand and windTemperature: maximum 60°C minimum -10°CMaximum humidity: 90%The respect of the instructions on the exterior side of the packaging assures the physical and functional integrity of theunit for the final user’s advantage.It is recommended to:Handle carefullyKeep in a dry placeAvoid putting other objects on top of the unit (respect the limits of levels of superimposition shown in the package)Avoid placing the unit with thermoretractable protection under the sun since the pressure of the circuits can assumevalues which activate the safety valves.HANDLINGThe operation of handling the unit must be carried out respecting the instructions of the safety norms in force (LegislativeDecree 626/94 and following modifications)Before starting the handling operations:Verify that the lifting capacity of the means used is adequate to the unit weightConsider that the barycentre could be moved with respect to the center of the unit.REMOVING THE PACKINGFor removing the packaging, use specific personal protection for the operator (gloves, glasses, etc.).Remove the polystyrene packaging making sure not to damage the unit..Check for any visible damage.Dispose of the packaging by taking it to specialist collection or recycling centres, in accordance with local regulations.HOISTING USING A CRANE OR SIMILARAttach the slings to the yellow lifting brackets provided.When lifting, it isabsolutely essential that a beam or other rigid spacer should be used sothat no pressure will be applied to the top part of the unit by the slingswhen under tension.Gradually bring the lifting belts under tension, making sure they arepositioned correctly. Make sure the unit is always in steady equilibrium.(refer to “Weight Distribution” for the position of the centre of gravity).Commence lifting.FUNCTIONAL CLEARANCESWhen placing the unit, please make sure that the functional clearances indicated on DIMENSIONS chapter, allow allmaintenance operations to be performed. this is required for optimum unit operation and particularly for the safety ofauthorised personnel and exposed persons.In the event of multiple units, the functional clearances must be doubled.14 MSAT-SC M49W40L5

- RECEPTION/POSITIONING -POSITIONINGThe units are designed for the exterior installation in a fixed position and in areas which can be easily reached byqualified and specialized personnel.The choice of where to position the unit is of fundamental importance for its use and working.Obstacles to the air flow , difficulties of air circulation , Leaves or other objects which can obstruct the exchange coils,winds which contrast or favor too much air flow, phenomena’s of stratification or of air circulation, sources of heat in thenearby vicinity, are cause working anomalies or stop the machine.During SUMMER usage, the increase of the condensate pressure with a drop of performances can cause blocksbecause of high pressure .In WINTER operation decrease of the evaporation pressure and increase of the number of defrosting increases with thedecay of performances and possible stops due to low pressure.Installations below ground level or near very high walls must be carefully assessed.Avoid installation in areas that may be subject to flooding.Install the unit raised from the ground, also considering the maximum level that can be reached in case of snow.During the WINTER operation, the heat pump produces a great quantity of condensation water..Verify that the condensation drain tube does not cause any problems to people or things (for example, dropping fromterraces, walking places, etc.)Check that the fastening/support points are in level and can bear the weight of the unit (see weights and weightdistribution).Place a layer of rubber between the base of the unit and the support to prevent noise and vibrations.It is recommended the use of spring antivibration mounts if steel wire netting structure are installed. The assembly onantivibration mounts, spring or rubber, requires flexible joints on all the unit connections (hydraulic, aeraulic orrefrigerant).Fasten the unit to the ground; when placing the unit where there are strong winds, foresee windbreak barriers.15 MSAT-SC M49W40L5

- REFRIGERANT PIPES -- REFRIGERANT PIPES -The sizing of the refrigerant connection lines is of extreme importance for the system operating and reliability.The diameter of the connection between the two units is function of distances, differences in level and curve number; ithas so to be calculated by a qualified technician. Incorrect sizing may damage the compressor or affect cooling capacity.The installation of the pipes may affect the level of noise in the system.install flexible joints between the unit and the pipes.• The operations must be performed by an expert refrigerator technician• Use only a copper pipe for chiller operating• Pipes must not to be too much long and with too much curves• For a good efficiency do not perform curves with a radium too much short and avoid the pipe crushing• To allow the vacuum and charge operations install service fittings on pipes (if the unit is not fitted with taps withservice fittings)• The pipe weight has not to weigh on units but it has to be sustained by anchorage brackets• Brackets must allow the pipe thermal expansion• Install antivibration material between the brackets and the pipes so as to prevent the transmission of vibrations• Pipes must be perfectly clean (perform a cleaning with nitrogen or dry air before connecting the pipes to the twounits) and without humidity to allow a good vacuum operation.SUCTION LINEThe pipe must be always insulated.In the horizontal sections, the incline must be to the compressor to allow the oil return also at the min. charge conditions.COMPRESSOR IN THE BOTTOMIf the condensing unit is lower than the evaporating unit:• make a drain tap at the same height as evaporating coil toprevent, when the machine is off, liquid from returning tothe compressor (to avoid the drain tap, fit on the liquid linea solenoid valve, always recommended)• install a tap near the evaporating unit (to avoid that thethermostatic bulb is into contact with some liquid when theunit is off)COMPRESSOR IN THE TOPIf the condensing unit is higher than the evaporating unit:• make a tap as near as possible to the evaporating unit• make an oil tap every 6 metres of vertical riseLIQUID LINEThe liquid line must be insulated if it is exposed to the sunlight or it crosses zones with a temperature higher than theexternal one, otherwise it can be free. Avoid excessive diameters to not cause an excessive refrigerant charge.The solenoid valve avoids dangerous gas leaks when the unit is off; the installation is always recommended, above allwith pipes particularly long. It has to be positioned near the thermostatic valve.19 MSAT-SC M49W40L5

- REFRIGERANT PIPES -LIQUID RECEIVERThe liquid receiver installation is always recommended, above all when:• the connecting pipes are longer than 10 metres• the installation operates in variable climatic conditions (for example external air temperature with rangesday/night, summer/winter).The receiver must have a capacity adequate to the installation and it must be positioned near the evaporating unit.If the distance is greater than 15 metres and the compressor is located in the lower part of the system, position thereceiver near the unit with the compressor.The liquid receiver can absolve the above described functions:• it avoids the presence of gaseous freon in the expansion device.• It compensates for the charge variations in the installation when changing the operating conditions• It avoids an excessive condenser flooding with consequent condensing temperature/pressure raising if theinstallation charge is performed in anomalous climatic conditions.CHECKING FOR LEAKS• Check carefully that the condensing unit taps are closed.• Connect the pressure gauges with the service fittings (on the taps or on the connection pipes).• Pressurise with refrigerant to 250KPa.• Close the valves on the pressure gauge assembly, then disconnect the refrigerant freon bottle andsubsequently connect the nitrogen bottle.• Open the valves on the pressure gauge.• Pressurise the system with nitrogen to 1200KPa.• Carefully check all the pipes using a leak detector or other electronic instrument, with special attention to thewelds and joints in general.• If the necessary equipment is not available, make sure any parts that may give rise to refrigerant leaks (welds,joints etc.) are accessible.EXTERNAL UNITINTERNAL UNITGas tapLiquid tap20 MSAT-SC M49W40L5

- START-UP -- START-UP -ALL THE EQUIPMENT MUST BE COMMISSIONED BY AUTHORISED SERVICE CENTRES.THIS SERVICE IS LIMITED TO START-UP OF THE UNIT ONLY AND NOT THE CONNECTIONS OR INSTALLATIONOF THE SYSTEM.ONLY QUALIFIED TECHNICIANS MUST PERFORM THE FOLLOWING OPERATIONS.PRELIMINARY CHECKSBefore checking, please verify the following:• the unit should be installed properly and in conformity with this manual.• the electrical power supply line should be sectioned at the beginning.• the sectioning device is locked and the proper warning “not to operate” sign is placed on the handle.• using a Voltmeter or a tension finder, make sure no tension is present.EMPTYING OPERATIONSCarefully check the refrigerating circuit: the presence of oil stains can mean leakage caused by transportation,movements or other.Make sure that all the service outlets are closed with proper caps; if caps are not present a leak of refrigerant can bepossible.Empty the system, with taps on the unit always closed.With the help of a pressure gauge connect the vacuum pump to both the service fittings, making sure that any shut-offdevices (solenoid valves or intermediate taps) are open, and then empty the system.Stop the pump when the pressure is around 100Pa, and then let the system stand for a few hours; a small initial rise inpressure is normal, after which it will stabilise definitively. If the pressure continues to rise, there may be small leaks ormoisture in the system. In the case of the former, repeat the operations described in the paragraph on CHECKING FORLEAKS. In the latter case refill the system with refrigerant gas until 100KPa and then empty the system as describedabove. When the pressure has stabilised definitively, move on to the subsequent filling phase.REFRIGERANT CHARGEThe units are shipped with a minimum charge with the only sealed function, to complete in the start-up phase followingthe internal terminal unit type and the pipe development.With the vacuum system, close the pressure gauge taps and disconnect the vacuum pump.Connect the refrigerant gas bottle, venting the air in the connection rubber with the pressure gauge.Open the liquid line tap.Open the pressure gauge taps and leave entering refrigerant (liquid status) by through a fitting pump.Once finished the charge, open the gas tap to allow the unit start-up.GASLIQUIDO24 MSAT-SC M49W40L5

OPERATE SAFELY) verify the following:• power supply tension• unbalancing of the phases• total absorption of the unit• absorption of the single electrical charges (compressor, fans, electric heaters and pumps if present).25 MSAT-SC M49W40L5

- START-UP -UNIT EQUIPPED WITH SCROLL COMPRESSORS.The general technical data table refers the type of compressor the unit is equipped with.Scroll compressors have a unique rotation direction.In the event it is inverted, it does not damage the compressor, but increases its noisiness and negatively affectspumping. after a few minutes, the compressors get blocked because of the thermal protection. in this event, unplug theunit and invert the two phases on the machine power supply.Prevent the compressor from working in a reverse rotation: more than 2 or 3 anomalous starts can damage thecompressor.Make sure that the rotation direction is correct and measure the condensation and suction pressure. Pressures must bevery different: at the start, the suction pressure increases whilst the condensation pressure increases.The optional phase monitor, than controls the phase sequence, can be in case installed also later.REFRIGERANT CIRCUIT PARAMETER CHECK PDCWhen the unit works in stable conditions and according to the operating limits, take note of the following data:- compressor discharge temperature (WARNING – BURN DANGERI)- condensing pressure- liquid temperature- dehydrator filter upstream and downstream temperature- inlet pressure- inlet temperature- input water temperature- output water temperature- external air temperature (battery input)- air temperature coming out from fansCheck the refrigerant charge correctness using the values of superheating, subcooling and the compressor dischargetemperature.THE CHARGE COMPLETION MUST BE PERFORMED IN GASEOUS PHASE DOWNSTREAM THE THERMOSTATICVALVE.Check after a short operating period, le oil level of every compressor.The data will be useful to check the unit in the future; therefore, it is important that the data are kept carefully and areavailable when maintenance is performed.26 MSAT-SC M49W40L5

- ROUTINE MAINTENANCE -- ROUTINE MAINTENANCE -PREVENTIVE MAINTENANCEAll equipment is subjected to wear out.The maintenance allows to reduce the deterioration speed, maintain the unit efficiency and prevent possible faults.Therefore, it is fundamental to perform periodical checks: I SERVIZI they are mainly cleaning activities, theINSPECTIONS foreseen the unit status and operating check.The machine should have a log book used to keep track of the performed controls. This will make fixing up breakdownseasier. Take note of the date, type of control (autonomous maintenance, inspection or fixing up), description of thecontrol, actions taken and so on.AUTONOMOUS MAINTENANCEThis section is dedicated to the user and is extremely important to help make the unit work properly in the future.A few operations performed carefully and periodically can avoid the interventions of specialized personnel.These operations do not need special technical skills and concern the following parts:• EXTERNAL AIR COIL• STRUCTUREBEFORE PERFORMING ANY MAINTENANCE OR CLEANING OPERATIONS, CUT THE POWER TO THE UNIT ANDMAKE SURE THAT NO ONE ELSE CAN SUPPLY POWER.EXTERNAL AIR COILATTENTION: contact with the exchanger fins can cause cuts. Wear protective gloves to perform the above describedoperations.It is extremely important that the battery gives the maximum thermal exchange; therefore, its surface must be cleanedfrom dust and deposits. Remove all impurities from the surface.Using an air pressure gun, clean the aluminum surface of the battery. Be careful to direct the air in the opposite directionof the fan air movement. Hold the gun parallel to the fins to avoid damages. As an alternative, an aspirator can be usedto suck impurities from the air input side.Verify that the aluminum fins are not bent or damaged. In the event of damages, contact the authorized assistancecenter and get the battery “ironed out” in order to restore the initial condition for an optimal air flow.STRUCTURECheck 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 thepanelling is fastened correctly. Poor fastening may give rise to malfunctions and abnormal noise and vibrations.MAINTENANCE INSPECTIONSForesee inspection assistance carried out by authorized centers 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 warming unitsThe frequency, however, depends on the use: in the event of frequent use (continuous or very intermittent use, near theoperating limits, etc) or critical use (service necessary) it is recommended to plan inspections at close intervals.The inspections to be performed are as follows:• verify the power supply tension when emptied or filled• inspect the electrical board (status of solenoid starter contacts, terminal closings, the status of wiring andrelevant insulations)• inspect the absorption of the single electrical loads (compressors, carter heaters, electric heaters, fans)• verify the cleaning and the efficiency of the exchangers• verify the leakage from the refrigerating circuit31 MSAT-SC M49W40L5

- ROUTINE MAINTENANCE -• check the operating parameters of the refrigerating circuitoWhen the unit works in stable conditions and according to the operating limits, take note of thefollowing data:- compressor diacharge temperature- condensing pressure- liquid temperature- dehydrator filter upstream and downstream temperature- inlet pressure- inlet temperature- external air temperature (battery input)- air temperature coming out from fansPUT AT RESTIf a long period of inactivity is reccomended, ad esempio la fermata invernale per unità di solo raffreddamento, èopportuno:• to turn the power off in order to avoid electrical risks or damages by lightning strikeIf the period of inactivity is particularly long or in the event of extremely low temperatures, the external fans can beblocked temporarily; therefore, it is recommended to switch them on every month in order to avoid seizures or electricaloverloads when the unit will be switched on.The restarting of the unit has to be carried out by qualified personnel, in particular, after the winter break for cooling unitsor when seasonal switching should be performed.When restarting, refer to the START-UP section.Schedule technical assistance in advance to avoid hitches and be able to use the installation when necessary.32 MSAT-SC M49W40L5
