A. THIS AIR CONDITIONER IS DESIGNED FOR:
1. Installation on a recreational vehicle during the time the vehicle
is manufactured.
2. Mounting on the roof of a recreational vehicle.
3. Roof construction with rafters/joists on minimum of 16 inch
centers.
4. Minimum of 2.00 inches and maximum of 4.00 inches distance
between roof to ceiling of recreational vehicle. Alternate in-
stallation methods will allow for roofs more than 4.00 inches
thick.
B. 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. During extremely
high outdoor temperatures, the heat gain of the vehicle
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. Avoiding the use of heat producing appliances
Operation on High Fan/Cooling mode will give optimum
ormaximumefciencyinhighhumidityorhighoutside
temperature.
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 a high heat gain,
accessories like A&E outdoor patio and window aw-
nings will reduce heat gain by removing the direct
exposure to the sun. They also add a nice area to enjoy
company during the cool of the evening.
C. Condensation
Note: The manufacturer of this air conditioner will not be
responsible for damage caused by condensed moisture on
ceilings or other surfaces. Air contains moisture and this
moisture tends to condense on cold surfaces. When air
enters the RV, condensed moisture 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 operation will minimize condensed moisture on cold
surfaces.
