INSTALLATION AND OPERATING INSTRUCTIONS

maintain an even temperature. The compressor will come on
as cooling is required to maintain the selected temperature
level.

Note: This electric heater will not replace a furnace for
heating your RV in cold weather. The intent is to remove the
chill on cool days or mornings.
A. Turn the selector switch to "OPT. HEAT".
B. The Heater will come on and begin heating.
C. When desired temperature level in RV is reached,
move the selector switch to off position or fan
position.

heating. There are three positions: HIGH FAN, MED.
FAN or LOW FAN to select from, depending upon
personal choice.

MAINTENANCE
SERVICE - Unit Does Not Operate
1. AIR FILTER:
Periodically remove the return air filter located above the
removable panel in the air box. Wash the filter with soap
and warm water, let dry and then reinstall.
Note: Never run the air conditioner without return air filter in
place. This may plug the unit evaporator coil with dirt and
may substantially affect the performance of the unit.
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 powders.
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 evapo-
rator coil. If this should occur, inspect the filter and
clean if dirty. Make sure air louvers are not obstructed.
Air conditioners have a greater tendency to frost when
the outside temperature 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.
If your unit fails to operate or operated improperly, check
the following before calling your service center.
1. If RV connected to motor generator, check to be sure
motor generator is running and producing power.
2. If RV connected to power supply by a land line, check
to be sure line is sized properly to run air conditioner
load and it is plugged into power supply.
3. Check your fuse or circuit breaker to see if it is open.
4. After the above checks, call your local service center for
further help. This unit must serviced by qualified service
personnel only.
When calling for service, always give the air conditioner
Model Number and Serial Number. This information can
be found on unit rating plate located on the base pan
near the return air opening. Return air grille must be
removed from air box to view.
