Control Panel
The air conditioner control panel is located on front of unit,
or behind control door on front frame.
Air conditioner controls include the vent control (not
available on all models), fan control, and temperature
control. Shown in Figure 3 are control panels for “cool
only” model air conditioners and for “heat/cool” model
units.
The following paragraphs explain the functions and
operation of each control.

Vent Control (not available on all units)
The vent control recirculates or exhausts room air by
opening or closing a damper (vent door).
When control is in
NORMAL
position, air in conditioned
area recirculates through air conditioner and back into
room. No air is exhausted (vented) outside.
NOTE: For maximum efficiency, keep vent control
in
NORMAL
position any time air conditioner is
cooling or heating.
When control is in
EXHAUST
position, room air is
exhausted (vented) outside. Use exhaust position to
remove stale or smoky air from area.
NOTE: To conserve energy, keep fan control in
FAN
ONLY
position when using exhaust feature.
Fan Control
The fan control enables the compressor and controls fan
motor operation. On heat/cool models, the control also
enables an electric heater.
The fan control settings include:
FAN ONLY
—Fan runs continuously at high speed and
compressor remains off. Use this setting to circulate air
without cooling and, with vent control in
EXHAUST
position, to vent room of stale air, odors, smoke, etc.
LOW COOL
—Fan runs continuously at low speed and
compressor cycles on and off, depending upon room
temperature. When on, compressor cools and
dehumidifies air circulating through air conditioner. Select
this setting for quiet operation.
MED COOL
—Fan runs continuously at medium speed
and compressor cycles on and off, depending upon room
temperature. When on, compressor cools and
dehumidifies air circulating through air conditioner.
HIGH COOL
—Fan runs continuously at high speed and
compressor cycles on and off, depending upon room
temperature. When on, compressor cools and
dehumidifies air circulating through air conditioner. Use
this setting for maximum air circulation and faster cool
down during initial start up.
HIGH HEAT—
(Heat/cool models only) Fan runs
continuously at high speed and electric heater cycles on
and off, depending upon room temperature. When on,
heater warms air circulating through air conditioner. Use
this setting for maximum air circulation and faster
warming during initial start up.
LOW HEAT—
(Heat/cool models only) Fan runs
continuously at low speed and electric heater cycles on
and off, depending upon room temperature. When on,
heater warms air circulating through air conditioner. Use
this setting for quiet heating operation.
OFF–
Turns air conditioner off.
CAUTION
To avoid tripping circuit breakers or blowing fuses,
wait two minutes after turning air conditioner off
before turning unit on again.
NOTE: Unplug air conditioner if it is to be turned off for an
extended period of time.
