A. INSTALLATION INSTRUCTIONS11. GENERALPolar Cat Junior air coolers are suitable for small cold and subzero rooms or cabinets usingrefrigerants and liquids, which do not corrode copper.The Manual also concerns E-model, where applicable (E=non-standard model). In these cases youalways have to check from delivery documents, in which way the difference has to be taken intonotice in installation, service and use.Wall mounting is possible with a drip tray A (without electric defrost) as accessory. The drip tray isattached on the air cooler, drip water connection is placed on the drip tray and the original hole isplugged. The model equipped with electric defrost (SSA) is ready-fitted at factory.Ceiling mountingPCJWall mounting with drip trayas accessoryPCJ A / SSAPCLPCL (AK)Fig 1.PCL, using the same construction, is a condenser suitable for indoor spaces and for roofedoutdoor spaces. Wall mounting is possible by using a fitting support (AK).

2. TRANSPORT AND STORAGEPolar Cat Junior air coolers are delivered in individual carton packages. When the air coolers arestored one upon the other, please note the light construction of the packing (max. 4 packings oneach other).Products may not be stored in humid outdoor spaces.3. PLACINGPolar Cat Junior air coolers shall be mounted so that their air flow is not obstructed and there isnothing to prevent the air flow in front of the equipment.In models equipped with electric defrost space is needed for changing the defrost theaters of the coilblock (fig. 2).Fig. 2.4.

19. ADDITIONAL REMARKSNOTE!Venting/draining valve of Polar Cat Junior G standard units are not adapted for refrigerant based onpotassium formiate; DANGER OF LEAKAGE!When using a refrigerant, which is based on potassium formiate, it has to be checked from thedocuments if the heat transfer section’s piping system and the venting/draining valves are adaptedfor the refrigerant.Instructions from refrigerant supplier have to be followed at installation, pressure test, use as well asin maintenance.NOTE!Applicability of the material of fins and heat transfer tubes to ambient conditions shall always bechecked to avoid external corrosion.In the air there should be no particles, which - together with water or other solvent condensing onthe surface of the heat transfer section - might form corrosive combinations. These combinationscan corrode the fins and tubes of the heat transfer section.

B. SERVICE INSTRUCTIONS2Trouble free operation of Polar Cat Junior air coolers and PCL condensers requires regular service.WARNING: Before starting service operations make sure that the circuit is reliably switched off.In service please check:• Outward condition of the equipment• Fixing of the equipment and of fans• Fan function• Defrost system• Cleanness of the coil block• Drainage1. COIL BLOCK AND DRIP TRAYThe coil block needs regular cleaning, if the air cooler is in use in dirty conditions or if the runningconditions require special cleanness.For cleaning the coil block open the fan plate, which the fan units are fixed on, very carefully(NOTE! The fan plate may not be hung on the jumpers only).The coil block can be vacuum-cleaned or washed (please do not use any strong alkaline detergentsor acids!). Recommendable detergent is e.g. ENVIRO-COIL.It is easy to clean the drip tray construction (PCJ) after opening the fan plate.2. FANSPolar Cat Junior air coolers and PCL condensers have 1-phase shaded-pole motors, fan blade diam.178 mm.Should the fan make any rattling or scratchy noise, stop it immediately and check its fixing points. Ifnecessary, replace the motor.

3. REPLACING A DAMAGED ELECTRIC COMPONENTPlease note, that an authorized person may only replace the damaged electric component.WARNING:Before changing the damaged component make sure that the circuit is reliably switched off!A new motor, defrost heater or thermostat:• Open the fan plate• Open the cover plate of the junction box• Release the cables of the damaged component• Replace the damaged component• Connect the new component• Check the earthing• Close the cover plate of the junction box• Close the fan plate• Make a test-runFig. 7
