Operate the air conditioner for five (5) to ten (10) minutes. No excessive noise or vibration should be evident during this run period. The condenser blower (ambient air), the evaporator blower (enclosure air), and the compressor should be running. Condenser air temperatures should be warmer than normal room temperatures within a few minutes. The compressor is provided with automatic reset thermal overload protection.

NOTE: For voltage, hertz, and options not shown in this manual, refer to the wiring diagram attached to the unit. CR43 Wire Diagram, Level II & III 8 317-257-6811 www.McLeanParts.net 10-1008-130 rev.
TEMPERATURE CONTROL The electromechanical thermostat is factory preset to 75oF/23oC. To change the temperature setting, remove the nylon plug from the back face of the unit. Use a standard screwdriver to adjust thermostat. For cooler temperatures turn clockwise, for warmer temperatures turn counterclockwise.
Do not run the air conditioner for extended periods of time with the filter removed. Particles of dust, lint, etc., can plug the fins of the condenser coil which will give the same reaction as a plugged filter. The condenser coil is not visible through the filter opening, so protect it with a filter. Continued operation under the above conditions can and will damage and shorten compressor life. The air conditioner is available with an easily removable inlet filter to facilitate necessary cleaning.
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) blower should come on. Is there airflow? YES, proceed to step # 3. NO, possible: Repair or Replace defective parts. Open motor winding Stuck blower motor Obstructed wheels/blades 3. Check thermostat setting? Adjust thermostat to the lowest setting.
Symptoms and Possible Causes: SYMPTOM POSSIBLE CAUSE Unit won’t cool * Blowers 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.
