INSTALLATION AND OPERATING INSTRUCTIONS

GENERAL INFORMATION

A. This air conditioner is designed for:

1. Installation on a recreational vehicle during or after

the time the vehicle is manufactured.

2. Mounting on the roof of a recreational vehicle.

3. Roof construction with rafters/joists on minimum of

400mm centers.

4. Minimum of 25mm and maximum of 100mm dis-

tance between roof to ceiling of recreational vehicle.

Alternate installation methods will allow for roofs

more than 100mm 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 cur tains)

3. Keeping windows and doors shut or minimizing

usage

4. Avoiding the use of heat producing appli ances.

5. Operation on High Fan/Cooling mode will give opti-

mum or maximum efficiency in high humidity or high

outside temperature.

6. 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.

7. For a more permanent solution to a high heat gain,

accessories like outdoor patio and window awnings

will reduce heat gain by removing the direct expo-

sure 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.
