TEMPERATURE CONTROL The electromechanical thermostat is factory preset to 75 F/23 C. To change the temperature setting, remove the nylon plug from the front face of the unit. Use a standard screwdriver to adjust thermostat. For cooler temperatures turn clockwise, for warmer temperatures turn counterclockwise. Setpoint differential is 6 F. Units With heat With a dial setting of 75 F, heat will turn on @ 70 F and turn off @ 75 F. Cooling will turn on @ 85 F and turn off at 80 F.
MAINTENANCE Compressor The compressor requires no maintenance. It is hermetically sealed, properly lubricated at the factory and should provide years of satisfactory operating service. Should the refrigerant charge be lost, recharging ports (access fittings) on the suction and discharge sides of the compressor are provided for recharging and/or checking suction and discharge pressures. Under no circumstances should the access fitting covers be loosened, removed or tampered with.
Condenser and Evaporator Air Movers Fan motors require no maintenance. All bearings, shafts, etc. are lubricated during manufacturing for the life of the fan. CAUTION Operation of the air conditioner in areas containing airborne caustics or chemicals can rapidly deteriorate filters, condenser coils, blowers and motors, etc. Contact Pentair Technical Products for special recommendations.
TROUBLE SHOOTING Basic Air Conditioning Trouble Shooting Check List 1. Check manufacturer’s nameplate located on the unit for correct power supply. 2. Turn on power to the unit. The evaporator (Enclosure or “COLD” air) fan should come on. Is there airflow? YES, proceed to step 3. NO, possible problem: • • • Open motor winding Stuck fan motor Obstructed blades Repair or Replace defective part 3. Check thermostat setting and adjust thermostat to the lowest setting.
Symptoms and Possible Causes: SYMPTOM POSSIBLE CAUSE Clogged fins on coil(s) Dirty filter Unit won’t cool fans not running Compressor not running Compressor runs, but has bad valves Loss of refrigerant Low line voltage at start. Should be +/-10% rated voltage.
