9. OPERATING INSTRUCTIONS
A. CONTROLS:
1. The Selector Switch has eight positions includ-
ing "OFF". This controls fan speed, heating
mode, and cooling modes. See FIG. 12
FIG. 12
2. The Thermostat controls the temperature range
o
from 65 F on the coldest side to 90
warmest side. In the cooling mode, the com-
pressor ON/OFF controlled by the thermostat
setting. See FIG. 12.
B. COOLING OPERATION:
1. Set the thermostat at the desired temperature
level.
2. Select the fan speed that best satisfi es your
needs:
a. HIGH COOL: Selected when maximum
cooling and dehumidifi cation required.
b. MED. COOL: Selected when normal or
average cooling required.
c. LOW COOL: Selected when room at
desired comfort level and needs to be
maintained. Normally this speed used for
night time operation.
Note: The blower runs continuously to circulate air and
maintain an even temperature. The compressor will come
on as cooling is required to maintain the selected tem-
perature level.
Important:
When the unit is turned on and the ther-
mostat calls for cooling, the compressor will start. After
shutting the unit down manually by either the selec-
tor switch or the thermostat, always wait 2-3 minutes
befor turning on the unit. This allows the refrigerant
pressure in the system to equalize so the compressor
may restart.

Thermostat
2. Air Box Housing:
Clean air box housing and control panel with
a soft cloth dampened with a mild detergent.
Never use furniture polish or scouring pow-
ders.
3. Fan Motor:
Factory lubricated and requires no service
under normal use.
4. Frost Formation On Cooling Coil:
Under certain conditions, frost may form on the
evaporator coil. If this should occur, inspect
the fi lter and clean if dirty. Make sure air lou-
vers are not obstructed. Units have a greater
tendency to frost when the outside tempera-
ture is relatively low. This may be prevented
by adjusting the thermostat control knob to a
warmer setting (counter clockwise). Should
frosting continue, operate on LOW, MED. or
HIGH FAN setting until the cooling coil is free
of frost.
