C. Louvers – The louvers are located at both ends of the
ceiling assembly shroud and are used in directing the
discharge air from the unit.
I. For Cooling (Refer to Figure 1, page 3).
A. Turn the selector switch to the "LOW COOL" or
"HIGH COOL" position.
B. Rotate the thermostat (temperature control) to the
position that is the most comfortable to you. The
thermostat will turn the compressor on when the
temperature of the air entering the air conditioner
rises a few degrees above the setting you have
selected. The temperature of the air
entering continues to cycle the compressor on and
off in the above mentioned fashion until the
selector switch is turned to another mode of
operation.
C. Position the louvers to the desired direction the
discharge air is to flow.
Note: The fan operation is constant, only the
compressor cycles on the thermostat.
II. Operation During Cooler Nights (Cooling
Operation).
It is important, when the outdoor temperature drops in the
evening or during the night to below 75 degrees F., that the
thermostat (temperature control) be set at a midpoint between
"Warmer" and "Cooler". If the setting is at "Cooler", the

evaporator coil may become iced-up and stop cooling. During
the day when the temperatures have risen above 75 degrees F.,
reset the thermostat switch to the desired setting.
Should icing-up occur, it is necessary to let the cooling
(evaporator) coil defrost before normal cooling operation is
resumed. During this time, operate the unit in the "HIGH
FAN" position with the system at maximum air flow. When
increased or full air flow is observed, the cooling coil should
be clear of ice.
III.
When an air conditioner is in operation, its compressor
circulates refrigerant under high pressure. Once off, it will
take two to three minutes for this high pressure to equalize.
The air conditioning compressor is unable to start against high
pressure. Therefore, once the air conditioner is turned off, it is
important to leave it off for two to three minutes before
restarting.
Short cycling the compressor (or starting it before pressures
have equalized), will in some instances, kick the circuit
breaker or overload.
