TEST FOR FUNCTIONALITY BEFORE MOUNTING THE AIR CONDITIONER TO THE ENCLOSURE. Refer to nameplate for proper electrical current requirements, then connect power cord to a properly grounded power supply. Minimum circuit ampacity should be at least 125% of the amperage shown in the design data section for the appropriate model. No other equipment should be connected to this circuit to prevent overloading. Operate the air conditioner for five (5) to ten (10) minutes.

TEMPERATURE CONTROL The electromechanical thermostat is factory preset to 75oF/24oC. To change the temperature setting, remove the nylon plug (if applicable) from the back face of the unit. Use a standard screwdriver to adjust thermostat. For cooler temperatures turn clockwise, for warmer temperatures turn counterclockwise. The set point of the thermostat equals the off temperature. The on temperature is 10°F/5oC above the set point. UNITS WITH HEAT The heating thermostat is factory preset to 55°F/13oC.
Inlet Air Filter Proper maintenance of the inlet air filter, located behind the front cover, will assure normal operation of the air conditioner. If filter maintenance is delayed or ignored, the maximum ambient temperatures under which the unit is designed to operate will be decreased.
Condenser and Evaporator Air Movers Impeller motors require no maintenance. All bearings, shafts, etc. are lubricated during manufacturing for the life of the motor. If the condenser impeller motor (ambient impeller) should fail, it is not necessary to remove the air conditioner from the cabinet or enclosure to replace the blower. The condenser blower is mounted on its own bulkhead and is easily accessible by removing the lower access panel.
TROUBLE SHOOTING Basic Air Conditioning Trouble Shooting Check List 1. Check manufacturer’s nameplate located on the unit for correct power supply. 2. Turn the power to the unit on. The evaporator (Enclosure or “COLD” air) impeller should come on. Is there airflow? YES, proceed to step # 3. NO, possible: 3. Repair or Replace defective part Open motor winding Stuck impeller motor Obstructed wheel Check thermostat setting? Adjust thermostat to the lowest setting.
Symptoms and Possible Causes: SYMPTOM POSSIBLE CAUSE Unit won’t cool * Clogged fins on coil(s) * Dirty filter * Impellers not running * Compressor not running * Compressor runs, but has bad valves * Loss of refrigerant Compressor tries to start but won’t run * Low line voltage at start.
