Preparing the installation
NOTICE!
- The refrigerator may not be installed in the rear of mobile homes with the door pointing in the direction of travel.
- Use exclusively original Dometic ventilation grills to ensure safe operation.
When installing the refrigerator, note the following:
- To enable the refrigerant to circulate properly, the refrigerator may not exceed an angle of 3°.
Park the vehicle horizontally for this purpose. - The refrigerator must be installed so that
– it is easily accessible for service work
– easy to de-install and install
– can be easily removed from the vehicle - The refrigerator must be installed in a recess so that it stands firm when the vehicle is in motion. Note the dimensions in fig. 1, page 3 for this purpose.
- The outer wall must be fitted with an air inlet vent (fig. 2 1, page 3) and an outlet vent (fig. 2 2, page 3) with ventilation grills so that the heat generated can be easily released to the outside:
– Air inlet vent: Fit ventilation grill as flush as possible with the base of the installation niche.
– Outlet vent: fit as far above the refrigerator as possible.
– The distance between the air inlet and outlet vents must be at least 1050 mm (fig. 3, page 4).
- Fit a heat conduction plate (fig. 3 1, page 4) above the refrigerator so that the heat does not accumulate in the vehicle.
- The distance between the refrigerator and the rear wall must be at least 15 mm but no more than 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 create adequate air inlet and outlet ventilation (fig. 4, page 4). 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 (fig. 5 1, page 5) if you need to install the roof vent offset; otherwise, heat will accumulate there.
– The distance between the air inlet vent and the roof vent must be at least 1350 mm (fig. 5, page 5).
– If a roof air conditioner is provided, the distance between the roof vent
(fig. 6 1, page 5) and the air outlet of the roof air conditioner (fig. 6 2, page 5) 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.
- 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 refrigerator must be installed in a draft-proof location.
Installing the refrigerator in a draft-proof location
WARNING! Fire hazard!
- Do not use flammable materials such as silicone sealants, foam or similar for the draft-proof installation.
- Position the device so that no connection cable is damaged or pinched.
- Do not use multiple sockets or portable power adapters behind the device.
Gas-powered refrigerators in camper vans or mobile homes must be installed in a draft-free location. This means that the combustion air is not extracted from the inte-rior and the exhaust fumes are prevented from directly entering the living space.
A suitable seal must be fitted between the rear panel of the refrigerator and the interior of the vehicle.
The manufacturer recommends using a flexible seal to ease removal and installation for maintenance purposes.
Select one of the three versions for draft-proof installation (fig. 7, page 6):
Stop bar behind the fridge (A)
- Glue a flexible sealing lip (1) to a stop bar (2) behind the refrigerator (3).
- Push the refrigerator-oven combination against the stop bar with the flexible sealing lips.
- The space behind the refrigerator is sealed to the interior of the vehicle.
Side gap distance of up to 5 mm between refrigerator and furniture (B)
- Glue the sealing lips (see chapter “Accessories” on page 13) on the side of the furniture (4).
- Push the refrigerator-oven combination against the flexible sealing lips on furniture.
- The space behind the refrigerator is sealed to the interior of the vehicle.
Side gap distance of 5 mm to 10 mm between refrigerator and furniture (C)
- Glue the double lipped sealing (see chapter “Accessories” on page 13) on the side of the furniture (4).
- Push the refrigerator-oven combination against the double lipped sealing on furniture.
- The space behind the refrigerator is sealed to the interior of the vehicle.
Making air inlet and outlet vents
- Deviations from the inlet and outlet variations shown here must be approved by the manufacturer.
- At high ambient temperatures, the refrigerator can only provide its maximum cooling capacity if the optimum ventilation has been pro-vided.
- Make an air inlet vent and an air outlet vent in the outer wall with the size of
– LS230: 315 mm x 373 mm
– LS330: 249mm x 410mm
When doing so, observe the information, see chapter “Preparing the installation” on page 15.
If the ventilation grill of the air inlet vent cannot be installed flush with the floor of the niche, install an inlet vent in the floor. Any leaking gas can thus flow downwards.
- Make an air inlet vent of at least Ø 40 mm in the floor (fig. 8 1, page 7) behind the refrigerator near the gas burner.
- Shield the outside of the opening with a deflector to prevent sludge or dirt from getting inside while driving (fig. 8 2, page 7).
If you have to use a roof vent instead of the air outlet 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 in chapter “Preparing the installation” on page 15.
Installing the ventilation grill
NOTE Use exclusively original Dometic ventilation grills to ensure safe operation. 
- Seal the installation frame to make the connection waterproof (fig. 0, page 7).
- Insert the installation frame and screw it down tightly (fig. a, page 7). Use all the fixing holes for this.
- Insert the ventilation grill as shown (fig. b, page 8).
Installing condensation drain
- Condensation can form inside the refrigerator due to frequent door opening, incorrectly stored food or food that is stored when it is too warm.
- Condensation must be drained with a constant slope.
Install the condensation drain as follows:
Variant 1 : Run the condensation hose from the refrigerator through an opening in the floor which goes outside under the vehicle.
Variant 2:
- Seal the installation frame to make the connection waterproof (fig. e, page 8).
- Insert the installation frame and screw it down tightly (fig. f, page 8). Use all the fixing holes for this.
- Insert the hood and screw it down tightly (fig. g, page 8).
Securing the refrigerator
CAUTION!
Only screw through the receptacles provided, otherwise foamed components, such as cables, can be damaged.
NOTE
Attach the side walls or the attached strips so that the screws are tight, even when under increased loads (while driving).
- Move the refrigerator into its final location.
- Fasten the six screws (fig. h 1, page 9) through the six plastic washers in the sides of the refrigerator, and further into the wall.
- Put the caps (fig. h 2, page 9) onto the screw heads.
