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. It is used to alert
you to personal injury hazards. Obey all safety
messages that follow this symbol to avoid possible 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 hazardous situation which, if not avoided, could result
in death or serious injury.
CAUTION, used with the safety 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.
A. Product features or specications 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 at 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 inches and maximum of 5-1/2 inches
distance between roof to ceiling of recreational
vehicle. Alternate installation methods will allow
for roofs more than 5-1/2 inches thick.
C. The ability of this 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 efciency in high humidity or high outside
temperatures.
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 Dometic 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. During normal operation this unit
removes moisture from the air. Keeping doors and windows
closed when this air conditioner is in operation will minimize
condensed moisture on cold surfaces.

INSTALLATION INSTRUCTIONS
A. Precautions
FIG. 1
9-1/2"
Improper installation may damage equipment,
could endanger life, cause serious injury and/
or property damage.
1. Read Installation and Operating Instructions carefully before attempting to start this unit installation.
2. Dometic, LLC will not be liable for any damages
or injury incurred due to failure in following these
instructions.
3. Installation must comply with the National Electrical Code ANSI/NFPA-70 and CSA Standard C22.1
(latest edition) and any State or Local Codes or
regulations.
4. DO NOT add any devices or accessories to this
unit except those specically authorized in writing
by Dometic, LLC.
5. This equipment must be serviced by qualied
personnel and some states require these people
to be licensed.
B. Choosing Proper Location For The Unit
This unit is specically designed for installation on the
roof of a recreational vehicle (RV). When determining
your cooling requirements, the following should be
considered:
• Size of RV;
• Window area (increases heat gain);
• Amount of insulation in walls and roof;
• Geographical location where the RV will be used;
• Personal comfort level required.
1. For one unit installation: The unit should be mounted
slightly forward of center (front to back) and centered from side to side.
2. For two unit installations: Install one unit 1/3 and
one unit 2/3’s from front of RV and centered from
side to side.
It is preferred that the unit be installed on a relatively at
and level roof section measured with the RV parked on a
level surface, but up to a 8° tilt is acceptable.
3. After Location Has Been Selected:
a. Check for obstructions in the area where unit
will be installed. See FIG. 1.

b. The roof must be designed to support 130
pounds when the RV is in motion. Normally a
200 lb. static load design will meet this requirement.
It is the responsibility of the installer of this
system to ensure structural integrity of the
RV roof. Never create a low spot on the roof
where water will collect. Water standing
around the unit may leak into the interior
causing damage to the product and the RV.
c. Check inside the RV for return air grill ob-
structions (i.e. door openings, room dividers,
curtains, ceiling xtures, etc.) See FIG. 2.
