GENERAL INFORMATION
Product features or specications as described or il-
A.
lustrated are subject to change without notice.
This Air Conditioner/Heat Pump (hereinafter referred
B.
to as the "unit" Is Designed For:
1. Installation on a Caravan or Motor Home during or
after the time the vehicle is manufactured.
2. Mounting on the roof of a Caravan or Motor Home.
3. Roof construction with rafters/joists support frames
on minimum of 406 mm centers.
4. Minimum of 25 mm and maximum of 140 mm
distance between roof to ceiling of Caravan.
C. Basic Requirements
1. Installation opening. Cut through the roof and ceiling.
2. 220-240 VAC, 50 Hz. 10 Amp.
3. Power when the unit starts must be above 198 VAC
and the frequency must be 50 Hz at all times.
D. The ability of the air conditioner to maintain the de-
sired inside temperature depends on the heat gain of
the Vehicle.
Some preventative measures taken by the occupants
of the Vehicle can reduce the heat gain and improve
the ability of the air conditioner to cool the Caravan.
During extremely high outdoor temperatures, the heat
gain of the Vehicle may be reduced by:
1. Parking the Vehicle 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, ac-
cessories 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.
E. 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
Vehicle, 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.

altitudes and from lack of maintenance.

B. Choosing Proper Location For The Unit
This unit is specically designed for installation on the roof
of a Caravan. When determining your cooling requirements,
the following should be considered:
• Size of Caravan or Motor Home;
• Window area (increases heat gain);
• Amount of insulation in walls and roof;
• Geographical location where the Caravan or Motor
Home will be used;
• Personal comfort level required.
1. Normal location-The unit is designed to t over an
existing roof vent opening.
2. Other locations - When no roof vent is available or
another location is desired, the following is recommended:
a. For one unit installation: The unit should be
mounted slightly forward of center (front to
back) and centered from side to side.
b. For two unit installations: Install one unit 1/3
and one unit 2/3’s from front of Caravan or
Motor Home and centered from side to side.

INSTALLATION INSTRUCTIONS
A. Precautions
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. The manufacturer will not be liable for any damages or injury incurred due to failure in following
these instructions.
3. The equipment shall be installed in accordance
with national wiring regulation per IEC 335-2-40, CI,
7.12.1. Installation must comply with all applicable
codes and/or regulations.
4. DO NOT add any devices or accessories to this
unit except those specically authorized in writing
by Dometic Mobicool.
5. This equipment must be serviced by qualied
personnel and some localities require these people
to be licensed.
It is preferred that the unit be installed on a relatively at
and level roof section measured with the Vehicle 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. 2.

b. The roof must be designed to support 65
Kg. when the Vehicle is in motion. Normally
a 100 Kg. static load design will meet this
requirement.
It is the responsibility of the installer of this
system to ensure structural integrity of the
Vehicle 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 Vehicle.
c. Check inside the Vehicle for air distribution
box obstructions (i.e. door openings, room
dividers, curtains, ceiling xtures, etc.). See
FIG. 3.
C. Roof Preparation
1. Opening requirements - Before preparing the ceiling opening, read all of the following instructions
before beginning the installation.
If an existing roof vent opening will not be used
a 362 mm x 362 mm (± 3 mm) opening must be
cut through the roof and ceiling of the Vehicle.
This opening must be located between the roof
reinforcing members.
There may be electrical wiring between the
roof and the ceiling. Disconnect 220 - 240
VAC power cord and the positive (+) 12 VDC
terminal at the supply battery. Failure to follow
this instruction may create a shock hazard
causing death or severe personal injury.

The 362 mm x 362 mm (± 3 mm) opening is part
of the return air system of the unit and must be
nished in accordance with all applicable national
and local codes and/or regulations.
2. Roof vent removal
a. Unscrew and remove the roof vent.
b. Remove all caulking compound around open-
ing.
c. Seal all screw holes and seams where the roof
gasket will be located. Use a good grade of all
weather sealant. See FIG. 4
FIG. 4
d. If the opening exceeds 365 mm x 365 mm, it
will be necessary to re-size the opening to 362
mm x 362 mm (± 3 mm).
e. If the opening is less than 359 mm x 359 mm,
it must be enlarged to 362 mm x 362 mm (± 3
mm).
3. New opening - (Installation other than vent opening)
a. Mark a 362 mm x 362 mm (± 3 mm) square
on the roof and carefully cut the opening.
b. Using the roof opening as a guide, cut the
matching hole in the ceiling.
c. The opening created must be framed to provide
adequate support and prevent air from being
drawn from the roof cavity. Framing stock 19
mm or more in thickness must be used. Remember to provide an entrance hole for power
supplies at the front of the opening. See FIG.
