Sheeting casingThe units are made of galvanized steel sheeting andanticorrosion nuts and bolts. Panels can be removed for ac-cess to internal components. The casing parts are paintedwith white RAL9001 oven-baked polymerized enamel.
CompressorsTwo hermetic Scroll compressors mounted in tandem on railsand antivibratory supports are used. Both compressors areconnected for operation with one single cooling circuit. Start-up is carried out by two independent starters. These com-pressors are equipped with electronic modules that protectthem against high operating temperatures. The sump heat-ers operate only when the compressor is inoperative.
Indoor heat exchangerComprises a stainless steel plate exchanger, adequately in-sulated by a layer of closed-cell elastomer foam. Includes anantifreeze heater monitored by the controller and a differen-tial pressure switch acting as a flow control switch. The re-frigerant side of said exchanger accepts an operating pres-sure of 30 bar, whereas the water side accepts 10 bar. Whenthe unit includes a Hydro Kit, maximum admissible pressureon the water side is 6 bar (adjustment of the tank relief valve).
Outdoor heat exchangerMade up of two notched aluminium fin coils and grooved cop-per tubing mechanically expanded within the fin assembly.
FansOf the axial and low sound level type. Equipped with single-phase motors with IP54 protection. These motors allow speedcontrol by means of a phase cut-out shifter controlled by theunit controller. This allows unit operation at low ambient tem-peratures (-10°C).On cool only units, an optional low ambient temperature kitcan reach -18°C. On heat pumps, the fan will remain inop-erative during defrosts.
Electric and control panelLocated at the front of the unit, and with IP44 protection. Theoperating and control components are factory mounted, wiredand tested. The door of this control panel is equipped with alocking isolator that turns power supply off. Inside we find thecontactors for compressors and the pump, the transformer,magneto-thermal protectors, controller electronic plates,speed control, connecting strip and the keyboard-display withthe unit controls.
Control keyboard-displayThis device is accessible through an external leak-tight plas-tic cover. This is an easy-to-use control with three accesslevels: Direct, User (password) and Factory (password). Forfurther information, please see Operating Instructions.
Cooling circuitThe cool only unit cooling circuit includes: expansion valve,filter-dryer, liquid sight glass, high and low pressure switches,service valves for isolating the condensing unit, and Schradervalves on the high and low sides. The heat pump model also
includes the four-way valve (powered in the summer cycleand during defrosts), the check valve and a liquid tank. Thesuction tubing is coated with closed-cell elastomer.
Hydro Kit (Pack)These units include a Pack assembled with the componentsof a Hydro Kit. This assembly is located within the unit frameand does not increase the footprint of same. It includes thefollowing components: Lined buffer tank with an antifreezeheater, centrifugal pump, expansion vessel charged with ni-trogen at 1.5 bar, relief valve set to 6 bar, water circuit pres-sure gauge, two air bleed valves, filling valve and drain valve.Also includes a mesh filter for the water circuit. This filter issupplied loose for installation at the most convenient point.

Heat exchange takes place between the heat transfer liquid(water or glycol water) and the refrigerant in the plate heatexchanger. Water is cooled, and refrigerant is evaporated andreheated. Then the Scroll compressor condenses the refrig-erant (gas) until the condensing pressure is reached, and therefrigerant goes to the air cooled condensing unit. In the aircooled condensing unit, heat is exchanged between the air
and the refrigerant. The air is heated and evacuated from thechiller (heat rejection). The refrigerant is condensed and sub-cooled. Then the refrigerant (liquid) goes on to the expansionvalve, where it is expanded until the evaporating pressure isreached, at which time it goes to the evaporating unit to starta new cooling cycle.

Cooling cycleThe 4-way valve is activated. Heat exchange takes placebetween the heat transfer liquid (water or glycol water) andthe refrigerant in the plate heat exchanger. Water is cooled,and refrigerant is evaporated and reheated. Then the Scrolltype compressor condenses the refrigerant (gas) until thecondensing pressure is reached, and the refrigerant goes tothe air cooled condensing unit. In the air cooled condensingunit, heat is exchanged between the air and the refrigerant.The air is heated and evacuated from the chiller (heat rejec-tion). The refrigerant is condensed and sub-cooled. Then the
refrigerant (liquid) goes on to the expansion valve, where it isexpanded until the evaporating pressure is reached, at whichtime it goes to the evaporating unit to start a new coolingcycle.
Heating cycleThe cycle is reversed to heating mode. The 4-way valve isnot activated. The condensing unit becomes the evaporatingunit, and the evaporating unit becomes the condensing unit.The water in the heat exchanger is heated.

Environmental protectionPackingPacking is made of recyclable material. Its eliminate shouldbe carried out in accordance with the existing local regula-tions on selective collection of residual material.
Elimination of the unitUpon disassembly of the unit, its components should be re-cuperated ecologically. The cooling circuit contains refriger-ant which should be recovered and returned to the gas manu-facturer for recycling.Oil will remain in the sealed compressor and, therefore, itmust be returned with its circuit sealed.The air conditioning unit will be deposited in an area estab-lished by the local authorities, for its selective recuperation.
SafetyInstallation and maintenance operations of this air condition-ing system should be carried out only by qualified and expertpersonnel. Periodical maintenance operations, such as clean-ing the coils and air filters, should be carried out so as tokeep unit performance at an optimum.
This unit should be installed and used in accordance with:- Low Voltage Electrotechnical Regulations.- Safety Regulations for Cooling Plants and Installations.- Regulations on Pressure Equipment.- Basic Construction Standards.- Local ordinances
TransportationThe units should always be transported in a vertical positionso as to avoid oil leaking out of the compressor. If, for anyreason, this position need be changed sporadically, they willremain in that position a strictly necessary period of time.
HandlingThis unit should be handled by using the metal rails suppliedfor fastening and transportation.
Warning signsThe following signs indicate the presence of possible dan-gerous conditions for the users or maintenance personnel.When found on the unit, their meaning should be taken intoaccount.
CAUTION
This symbol indicates an electrical riskor hazard.
Caution: The unit is equipped with a re-mote control system and can start auto-matically. Before having access to theinterior of the unit, disconnect the powersupply so as to avoid any contact withthe fan turbine in motion.
Caution: Fan in operation.
Caution: It is obligatory to read the in-structions prior to any handling.
Caution: Do not touch hot surfaces.
Attention: Possible gas leaks due to in-adequate handling.

LocationBefore locating the unit in place, check the specificationsdescribed on same to be sure you have received the ad-equate product.The unit should be placed on a perfectly horizontal plane,making sure the base can support the weight of the unit.If you want to insure the absence of vibration, the unit can beplaced on a cork or similar antivibratory base, or fastened toits base with antivibratory plates or supports.Figure 11 indicates the clearances and fastening points foreach model.
Fastening the unitBefore installing the unit, make sure the structure can with-stand the weight of same.If the unit is placed on the floor, a concrete base should beprepared so as to distribute its weight evenly. See Fig. 7.
ClearancesThe installation of each unit should have clearances for:a) Air intake and discharge.b) Maintenance servicing.c) Power supply connection.For correct operation, always respect the minimum distancesindicated in the general dimensions diagrams with regard topossible obstructions of free air circulation or maintenanceservicing.
WiringElectrical connectionsThe established national regulations should be followedin all cases.Each unit is supplied with a control box to which the powersupply will be connected through a fused main switch or anautomatic switch.
Loose cables can produce overheating of the terminals or an incor-rect operation of the unit. A fire hazard may also exist. Therefore,make sure all cables are connected tightly.
WARNING
Scroll compressors, rotational directionThe Scroll compressors, just like the fans, operate correctlyin one single rotational direction. When starting the equip-ment up, make sure this rotational direction is correct.If it is not correct:- The compressor does not compress.- It makes an unusual noise.- Amp consumption is lower.- It overheats.
Hydraulic connectionsThe hydraulic connections of the water intake and outlet ofthe chiller should be carried out respecting the intake andoutlet directions indicated.Galvanised iron or copper tubing can be use, with dimen-sions no lower than those indicated, and keeping in mind thepressure drops of said connections and of the internal ex-changer of the installation.Pump dimensioning should be carried out considering a nomi-nal flow that allows an ∆t within the operating limits.In all cases, a flow switch should be installed so as to avoidthe possibility of operation without water circulation.An expansion vessel should be installed in the water returntubing.This vessel must be adequate for the total water volume ofthe installation.During the winter season, with outdoor temperatures below0°C, precautions should be taken to avoid the water fromfreezing in the tubing networks.Usual application is to fill the circuit with an antifreeze mix-ture (glycol).
