SAFETY INSTRUCTIONS

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

RECOGNIZE SAFETY INFORMATION

This is the safety alert symbol. It is used to alert
you to personal injury hazards. Obey all safety
messages that follow this symbol to avoid pos-
sible injury or death.

UNDERSTAND SIGNAL WORDS

A signal word, when used with the safety alert
symbol, will identify a safety hazard and its level
of risk for personal injury. A signal word, without
the safety alert symbol, will be used for property
damage messages only.
WARNING indicates a hazard-
ous situation which, if not avoided, could result
in death or serious injury.
CAUTION, used with the safe-
ty alert symbol, indicates a hazardous situation
which, if not avoided, could result in minor or
moderate injury.
NOTICE is used to address
practices not related to personal injury.
Read and follow all safety information and
instructions to avoid personal injury.

GENERAL INFORMATION

A.
Product features or specifications as described or il-
lustrated are subject to change without notice.
B.
This air conditioner/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 inch and maximum of 4 inches dis-
tance between roof to ceiling of recreational ve-
hicle.
C.
The ability of the air conditioner to maintain the de-
sired 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 ve-
hicle 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 opti-
mum or maximum efficiency 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, ac-
cessories like Dometic outdoor patio and window awnings
will reduce heat gain by removing the direct exposure to
the sun. They also add a nice area to enjoy company dur-
ing 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, win-
dows, metal parts, etc. During normal operation this unit
removes moisture from the air. Keeping doors and win-
dows closed when this air conditioner is in operation will
minimize condensed moisture on cold surfaces.
