TEMPERATURE CONTROL

The electromechanical thermostat is factory preset to 75 F/23 C for cooling (Top thermostat) and 55 F/13 C for 

heating (Bottom thermostat). 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. Standard units have a factory installed lower limit of 70 F for cooling and a 

upper limit of 60 F for heating.

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. It takes a minimum of one (1) 

minute after shutdown for the compressor suction and discharge pressures to equalize in order for the air 

conditioner to restart.
Operating the air conditioner below the minimum ambient temperature or above the maximum ambient 

temperatures indicated on the nameplate voids all warranties.
It is recommended that the warranty section of this manual be read in order to familiarize yourself with 

parameters of restricted operation.
The moisture that the enclosure air can contain is limited. If moisture flows from the drain tube continuously this 

can only mean that ambient air is entering the enclosure. Be aware that frequent opening of the enclosure’s door 

admits humid air, which the air conditioner must then dehumidify.

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.
Breaking of seals on compressor access fittings during warranty period will void warranty on hermetic system.
Recharging ports are provided for the ease and convenience of reputable refrigeration repair service personnel 

for recharging the air conditioner.

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.
If the compressor’s operating temperature increases above designed conditions due to a dirty or clogged filter 

(or plugged condenser coil), the air conditioner’s compressor will stop operating due to actuation of the thermal 

overload cut-out switch located on the compressor housing. As soon as the compressor temperature has dropped 

to within the switch’s cut-in setting, the compressor will restart automatically. However, the above condition will 

continue to take place until the filter or coil has been cleaned. It is recommended that power to the air conditioner 

be interrupted intentionally when abnormally high compressor operating temperature causes automatic shut-

down of the unit. The above described shutdown is symptomatic of a clogged or dirty filter, thus causing a 

reduction in cooling air flow across the surface of the compressor and condenser coil.
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. There should be no 

reason to neglect this necessary maintenance.
