SAFETY INSTRUCTIONS

GENERAL INFORMATION

This manual has safety information and instruc­tions to help users eliminate or reduce the risk of
accidents and injuries.

RECOGNIZE SAFETY INFORMATION

!

This is the safety-alert symbol. When you see this
symbol in this manual, be alert to the potential
for personal injury.

Follow recommended precautions and safe op­erating instructions.

UNDERSTAND SIGNAL WORDS

A signal word , WARNING OR CAUTION is used
with the safety-alert symbol. They give the level
of risk for potential injury .

A. Product features or specifications as described or

illustrated are subject to change without notice.

B. This Air Conditioner Is Designed For:

1. Installation on a Caravan during the timethe Cara­van is manufactured.

2. Mounting on the roof of a Caravan.

3. Roof construction with rafters/joists on minimum of
406mm centers.

4. Minimum of 25mm and maximum of 100mm dis­tance between roof to ceiling of Caravan. Alternate
installation methods will allow for roofs more than
100mm thick.

C. The ability of the air conditioner to maintain the desired

inside temperature depends on the heat gain of the
Caravan.
Some preventative measures taken by the occupants of
the Caravan can reduce the heat gain and improve the
performance of the air conditioner. During extremely
high outdoor temperatures, the heat gain of the Caravan
may be reduced by:

1. Parking the Caravan 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 efficiency in high humidity or high outside
temperatures.

WARNING

!

indicates a potentially hazard­ous situation which, if not avoided, could result
in death or serious injury .

CAUTION

!

indicates a potentially hazard­ous situation which, if not avoided may result in
minor or moderate injury .

CAUTION

used without the safety alert
symbol indicates, a potentially hazardous situa­tion which, if not avoided may result in property
damage.

Read and follow all safety information and in­structions.

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,
accessories like an outdoor patio and window awning 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 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 Caravan, 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.

the roof of a Caravan. When determining your cooling
requirements, the following should be considered:

• Size of Caravan;

• Window area (increases heat gain);

• Amount of insulation in walls and roof;

• Geographical location where the Caravan will be used;

• Personal comfort level required.

1. Normal Location-The air conditioner is designed to
fit over an existing roof vent opening.

When sizing the generator, the total power usage of your
Caravan must be considered. Keep in mind generators lose
power at high altitudes and from lack of maintenance.
