GENERAL INFORMATION

A.
Product features or specifi cations as described or il-
lustrated are subject to change without notice.
B.
This "Air Conditionr" /"Heat Pump" (hereinafter referred
to as the "unit") 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 recre-
ational vehicle. Alternate installation methods will
allow for roofs more than 4.00 inches thick.
C.
The ability of the unit 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 unit. During extremely high out-
door 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.
5. Operation on High Fan/Cooling mode will give
optimum or maximum effi ciency in high humidity
or high outside temperatures.
6. Starting the unit early in the morning and giving it
a "head start" on the expected high outdoor ambi-
ent will greatly improve its ability to maintain the
desired indoor temperature.
7. For a more permanent solution to high heat gain,
accessories like A&E 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.
D. Condensation
Note: The manufacturer of this unit 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 unit removes this moisture
from the air during normal operation. Keeping doors and
windows closed when this unit is in operation will minimize
condensed moisture on cold surfaces.
