•The recommended maximum distance between the refrigerator and the rear wall
is 25 mm. A distance of more than 25 mm between the refrigerator and rear wall
leads to poor performance and increases the power consumption of the
refrigerator. Reduce the space behind the refrigerator to maximum 25 mm to
create adequate air inlet and outlet ventilation corridor (fig. 4and fig. 5). Use
a ventilation plate, for example, to do this.

•If the minimum distance between the air inlet and outlet vents cannot be met, a
roof vent must be installed instead of the air outlet vent.
– The roof vent should be installed directly above the back of the refrigerator as
far as this is possible. Use an air duct if you need to install the roof vent
(fig. 66) offset, otherwise heat will accumulate there.
– If a roof air conditioner is installed, the distance between the roof vent
(fig. 71) and the air outlet of the roof air conditioner (fig. 72) must be at
least 300 mm.
•The refrigerator must not be installed at the side of the air inlet and outlet vents as
this leads to poor performance and increases the power consumption of the
refrigerator.
•The air inlet and outlet vents must not be covered by vehicle parts (such as an
open door or by installing accessories such as bicycle racks) while operating.
•A separate flue duct must be installed under the air outlet vent, see chapter
“Installing the flue duct” on page 19.

•Install the refrigerator so that it is protected from excessive heat, as this leads to
poor performance and increases the power consumption of the refrigerator.
•The electrical installation must comply with national and local regulations.
•The gas installation must comply with national and local regulations.
– AS/NZS 5601.2 – Gas installations – LP Gas installations in caravans and boats
– AS/NZS 5601.1 – Gas Installations – General Installations
•The refrigerator must be installed in a draught-proof location, see chapter “Install-
ing the refrigerator in a sealed location separate to the living space” on page 13.
6.2 Installing the refrigerator in a sealed location
separate to the living space
Gas-powered refrigerators in caravans or motorhomes must be installed in a sealed
location. This means that the combustion air can not be extracted from the interior
and exhaust fumes are prevented from directly entering the living space.
A suitable seal must be provided and fitted between the rear wall of the refrigerator
cabinet and the interior of the vehicle. The purpose is to provide a seal between the
interior of the vehicle and the cooling unit and ventilation area behind the
refrigerator.
!
The manufacturer has applied a sealing strip to the rear surface of the front frame.
WARNING! Fire hazard!
Do not use flammable materials such as silicone sealants, foam or similar
for the draught-proof installation.

If you have to use a roof vent instead of an upper wall vent:
➤Cut out a section in the roof. Refer to the roof vent instruction manual for the
required dimensions. When doing so, observe the information, see chapter “Pre-
paring the installation” on page 6.
6.4 Installing the drain water hose
➤To avoid damage on the drain water hose, position the hole for the drain water
hose in a way, that the hose does not touch the boiler casing.
➤Drill a hole through the floor at the rear of the refrigerator.
➤Install the drain water hose through the drilled hole. Ensure, that the drain water
hose is long enough in order to drain the water outside of the vehicle.
➤Ensure that the drain water hose is not kinked.
➤Seal the area around the drain water hose.
