Page 8: Temperature Control
TEMPERATURE CONTROL The electromechanical thermostat is factory preset to 75 F/23 C. 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. PRINCIPLES OF OPERATION If electrical power to the air conditioner is interrupted and reapplied immediately, (within 3 to 5 seconds), the compressor may not restart due to the high back pressure of the compressor. - Page 9 The blower is mounted on its own bulkhead and is easily accessible by opening the front cover. Caution: Operation of the air conditioner in areas containing airborne caustics or chemicals can rapidly deteriorate filters, condenser coils, blower and motor, etc. Contact McLean Thermal for special recommendations. Refrigerant Loss Each air conditioner is thoroughly tested prior to leaving the factory to insure against refrigeration leaks.
