SECTION III. OPERATION UNDER USUAL CONDITIONS
2-5. OPERATING PROCEDURES.
a. General operation of controls. All controls necessary to operate the air conditioner and heater are located on
the control module. When the controls are properly set, the unit will automatically control the temperature. Do
not adjust controls unnecessarily. The temperature control thermostat on the control module operates like a
conventional room thermostat, except that the temperature scale is not marked on the control module. The
thermostat has a range of 40F to 90F (4C to 32C). A temperature sensor located on the bottom of the
control module senses the temperature.
High heat mode increases evaporator fan speed only.
High heat mode does not increase heat output.
b. Operation in HIGH HEAT or LOW HEAT. Position the mode selector switch to the HIGH HEAT or LOW HEAT
For initial operation ensure condensate drain on evaporator assembly is uncapped. Failure to uncap
condensate drain on evaporator assembly may result in equipment failure or damage.
c. Operation in HIGH COOL or LOW COOL. Position the mode selector switch to the HIGH COOL or LOW
COOL setting. Adjust the thermostat switch to select desired temperature.
d. Operation in HIGH FAN or LOW FAN. Position the mode selector switch to the HIGH FAN or LOW FAN
position. The evaporator blower will circulate air within the shelter. The evaporator blower does not exchange
shelter air with outside air.
e. Shutdown. Position the mode selector switch to the OFF position. No other action is necessary to shut down
the air conditioner.
