Environmental hints
Refrigerators manufactured by Dometic GmbH are CFC-free. Ammonia (a natural compound of hydrogen and nitrogen) is used in the cooling unit as a coolant. The non-ozone-hazardous cyclopentan is used as a propellant in the manufacture of the PU foam insulation.
Disposal
In order to ensure that the recyclable packaging materials are re-used, these should be sent to the usual local collection system. The appliance should be transferred to a suitable waste disposal company that will ensure re-use of the recyclable components and proper disposal of the rest. For eco-friendly draining of the coolant from all absorber refrigeration units, a suitable disposal plant should be used
Energy-saving tips
At an average ambient temperature of approx. 25°C, it is sufficient to operate the
refrigerator at the middle thermostat setting (for both gas and mains voltage).
Where possible, always store goods that have previously been cooled. Do not position the refrigerator in direct sunlight. Constant circulation of air must be supplied to the refrigerator unit. Defrost regularly. Open the door only for a short time when removing goods from the refrigerator. Run the refrigerator for about 12 hours before filling it.

INSTALLATION GUIDE
On installation of the appliance, the technical and administrative regulations of the country in which the vehicle will first be used must be adhered to. Otherwise the refrigerator must be installed as described in these instructions. In some OEM applica­tions it may not be possible for these instructions to be followed exactly. In this case an authorised Dometic representative may issue supplementary instruction
In Europe, for example, gas appliances, cable laying, installation of gas cylinders, as well as approval and checking for leaks must comply with DIN EN 1949 for liquid gas units in vehicles.
Installation
The appliance and its fume extraction shall be installed in such a way as to be acces­sible for servicing at all times and must be capable of easy removal and installation.
The appliance may only be installed by authorised personnel. Installation and connection of the appliance must comply with the latest technical regulations, as follows:
Technical regulations, EN 1949
Technical regulations, EN 732
The electrical installation must comply with national regulations ( EN 60335-1 for Europe).
The gas installation must comply with national regulations.
Local and building control department requirements
The appliance shall be installed in such a way that it is shielded from excessive heat radiation.
Excessive heat impairs performance and raises the energy consumption of the refrigerator.
Side Installation
If the appliance is installed on the same side of the vehicle as the entrance door, it is desirable that the door does not cover the refrigerators vents.
If this cannot be avoided there must be a gap of at least 25mm between the door and the vents.
Rear installation
If the refrigerator is mounted at the rear of the vehicle you must ensure the lower grille is not covered by the bumper or rear lights. This would be prevent the air from circulating properly and cause problems in warm weather.

Any installation that is not carried out by qualified persons will jeopardize the manufacturer's guarantee.
17
Draught-free installation
Your refrigerator must be sealed in accordance with EN 1949. Illustrated below are two typical approved methods of sealing.
Proposal 1:
Insert lipped seals (A) into the installation recesses at the bottom and at each side.
Insert deflector plate (B), fitted with a lipped seal (A) of heavy-duty, nonflammable material, into the installation recess (see Fig. 1).
Insert deflector plate (B) in such a way that the hot air escapes through the air vent grating into the open air.
Affix the discharge plate to the caravan wall, not to the refrigerator!
In addition, discharge plate (B) with its lipped seal (A) must seal the refrigerator off from the living area (see Fig. 1).
Ensure that the refrigerator is installed level in the recess.
Proposal 2:
Another option is to provide the refrigerator with a cowl (A). The cowl (A) should ideally be affixed to the caravan wall, not to the refrigerator. Insert sealing strips at the bot­tom and sides of the cover.
Finally, push the refrigerator into the cover from the front. Both of these installation options facilitate the removal and
installation of the appliance for servicing.
Comment:
Other methods of sealing may be approved. However the chosen method must prevent draughts entering the living space of the caravan or motorhome. Failure to seal correct­ly will allow warm air to collect around the refrigerator and its performance will be affected. If the cavity between the caravan wall and the refrigerator is sealed so that fumes cannot penetrate the living area it is possible to vent the flue gas directly through the upper grille without using the aluminium flue pipe. For this installation method, it is recommended that the same air vent grille should be used at the top and at the bottom (L200), and that the T-piece of the flue pipe is turned 45 degrees.
6.2
Fig.1
18
In this case, for gas operation, do not use the upper winter cover!
If even with draught-free installation a fume chimney is desirable, you must incorporte the L100 ventilation and extraction system into the upper air vent opening.
Installation of fume chimney: please refer to point 6.7.
Ventilation and extraction
A correct installation is important for correct operation of the appliance to ensure, there is no a build-up of heat at the back of the appliance; this heat must be allowed to escape into the open air.
In the event of high ambient temperatures, full performance of the cooling unit can only be achieved by means of adequate ventilation and extraction.
Ventilation is provided for the unit by means of two apertures in the caravan wall. Fresh air enters at the bottom, extracts the heat and exits through the upper grille.
The upper ventilation grille should be positioned as high as possible above condenser (A).
The lower ventilation grating should be flush with the floor of the vehicle, allowing any gas leakages (heavier than air) to escape directly into the open air.
If such an arrangement is not possible a hole must be provided under the refrigerator (not close to the burner) so that any leaking LP gas can escape. This must have an effictive area of at least 13cm². It is desirable to fit the hole with wire mesh or similar, and an angle plate to protect it from stones, mud etc., the wire mesh must not reduce the effective area of 13cm²
The ventilation gratings must have a free cross-sectional area of at least 250 cm

.
Dometic recommends using the L100/L200 ventilation and extraction system.
Comment:
If the distance between the wall and the refrigerator is greater than 20 mm the gap can be reduced to 20 mm by fitting a suitable baffle piece.

Installing the ventilation system
To install the ventilation grilles, cut two rectangles (451mm x 156mm) in the outer wall of the vehicle (for position of the cuts, see point 6.3).
Securing the refrigerator
In the sidewalls of the refrigerator, there are four plastic sleeves with screws for securing the refrigerator. The sidewalls or rails attached for securing the refrigerator must be designed in such a way that the screws will remain firmly in place even when
under increased load (while the vehicle is moving).
Always insert screws through the sleeves provided; otherwise, structural parts embedded in the foam, such as cables, etc., may be damaged.
Once the refrigerator is in its final position, secure the screws into the wall of the recess.
The screws must penetrate through the sheet metal casing of the refrigerator.

1. Seal the mounting frame, making it waterproof.
2. Insert the frame and screw into position.
3. Insert the ventilation grilles.
4. Lock the ventilation grilles.
5. Clip the extractor insert in position (only for upper ventilation system)
20
Installation recess
The refrigerator must be installed draught-free in a recess. The measurements of the recess are given in the table below. Step (A) is only required for cabinets with a step. Push the appliance far enough into the recess until the front edge of the refrigerator casing is flush with the front of the recess. Allow a gap of 15-20 mm between the back wall of the recess and the refrigeration unit. The floor of the recess must be level, allowing the appliance to be pushed easily into its correct position. The floor must be substantial enough to bear the weight of the appliance.
Ensure that the refrigerator is installed level in the recess.
