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 compres-
sor will come on as cooling is required to maintain the
selected temperature level.
AFTERSHUTTING THE AIR CONDITIONERDOWN
WITH EITHER SELECTOR SWITCH OR THERMO-
STAT, WAIT AT LEAST TWO (2) MINUTES BE-
FORE RESTARTING. THIS ALLOWS THE RE-
FRIGERANTPRESSURETO EQUALIZEANDCOM-
PRESSOR TO RESTART EASILY.
C. FAN OPERATION:
This will circulate the air in your RV without cooling or
heating. There are three positions: HIGH FAN, MED.
FAN or LOW FAN to select from, depending upon
personal choice.
D. HEATING OPERATION:
(With Optional Heat Kit Installed)
NOTE: This electric heater will not replace a fur-
nace for heating your RV in cold weather. The intent
is to remove the chill on cool days or mornings.
1. Turn the selector switch to "OPT. HEAT".
2. The Heater will come on and begin heating.
3. When desired temperature level in RV is
reached, move the selector switch to off posi-
tion or fan position. (NOTE: Thermostat does
not control heater ON/OFF cycle.)
E. "OFF" POSITION: This is to turn Unit off.
4. MAINTENANCE
A. 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 the reinstall.
NOTE: Never run the air conditioner without re-
turn air filter in place. This may plug the unit evapora-
tor coil with dirt and may substantially affect the
performance of the unit.
B. 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.
C. FAN MOTOR:
Factory lubricated and requires no service under
normal use.
D. 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.
5. GENERAL INFORMATION
The ability of the air conditioner to maintain the desired
inside temperature depends on the heat gain of the
RV. Some preventative measures taken by the
occupants of the RV can reduce the heat gain and
improve the performance of the air conditioner. Dur-
ing extremely high outdoor temperatures, the heat
gain of the vehicle may be reduced by:
a. Parking the RV in a shaded area
b. Using window shades (blinds and/or curtains)
c. Keeping windows and doors shut or minimizing
usage
d. Avoiding the use of heat producing appliances
Starting the air conditioner early in the morning and
giving it a "head start" on the expected high outdoor
ambient will greatly improve its ability to maintain the
desired indoor temperature.
NOTE
The manufacturer of this air conditioner will not be
responsible for damage caused by condensed mois-
ture on ceilings or other surfaces. Air contains mois-
ture and this moisture tends to condense on cold
surfaces. When air enters the RV, condensed mois-
ture may appear on the ceiling, windows, metal parts,
etc. The air conditioner removes this moisture from
the air during normal operation. Keeping doors and
windows closed when this air conditioner is in opera-
tion will minimize condensed moisture on cold sur-
faces.
6. SERVICE - Unit Does Not Operate
If your unit fails to operate or operated improperly,
check the following before calling your service center.
A. If RV connected to motor generator, check to be sure
motor generator is running and producing power.
B. 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.
C. Check your fuse or circuit breaker to see if it is open.
D. 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 condi-
tioner Model Number and Serial Number. This infor-
mation 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.
