B. Heat Gain
The ability of this 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 perfor-
mance of the air conditioner. During extremely high outdoor
temperatures, the heat gain of the RV may be reduced by:
1. Parking the RV in a shaded area
2. Using window shades (blinds and/or curtains)
3. Keeping windows and doors shut or minimizing
usage
4. Avoid the use of heat producing appliances
5. Keep return air lter clean
Operation on High Fan/Cooling mode will give optimum
or maximum efciency in high humidity or high outside
temperatures.
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.
For a more permanent solution to high heat gain, acces-
sories like Dometic outdoor patio and window awnings will
reduce heat gain by removing the direct sun. They also add
a nice area to enjoy company during the cool of the evening.
C. Unit Functions
1. Cools and circulates inside air (Spring/Sum-
mer/Fall).
2. Lowers humidity by removing excess moisture
(Spring/Summer/Fall).
3. Filters out dust, dirt, and other airborne impuri-
ties (Spring/Summer/Fall/Winter).
4. Heats and circulates inside air (Spring/Fall/
Winter).
The unit performs these functions by drawing room air
through a lter which traps dust and dirt particles. The air
then passes over the indoor conditioning coil which cools
and removes excess moisture (Spring/Summer/Fall) and
heats the air (Spring/Fall/Winter). The same air is then
returned to the living space to keep you comfortable.
D. Condensation
The manufacturer of this unit will not be responsible for
damage caused by condensation forming on ceilings,
windows, or other surfaces. Air contains water vapor which
condenses when temperature of a surface is below Dew
point. During normal operation this unit is designed to
remove a certain amount of moisture from the air, depend-
ing on the size of the space being conditioned. Keeping
doors and windows closed when this air conditioner is in
operation will greatly reduce the chance of condensation
forming on interior surfaces.
E. Drain Tube
1. The drain tube should be left unplugged during
heating operation, storage, and any time when
traveling after the unit has been operating.
F. Heat Pump Operation
1. Heat pump mode will not operate when the out-
side temperature is 30° F and below. If heating
is required switch over to furnace mode if ap-
plicable.
