INSTALLATION GUIDE
On installation of the appliance, the technical and administrative regulations of the
country in hich the vehicle ill first be used must be adhered to. Other ise the
refrigerator must be installed as described in these instructions. In some OEM applica-
tions it may not be possible for these instructions to be follo ed 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 ay as to be acces-
sible 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, liquid gas (TRF 1996)
Technical regulations, DV W Worksheet 607 (DIN 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 bet een the door and
the vents.
Rear installation
If the refrigerator is mounted at the rear of the vehicle you must ensure the lo er grille
is not covered by the bumper or rear lights.
This ould be prevent the air from circulating properly and cause problems in
arm eather.

Any installation that is not carried out by qualified persons will
jeopardize the manufacturer's guarantee.

Draught-free installation
Your refrigerator must be sealed in accordance ith EN 1949.
Illustrated belo are t o 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 ith a lipped seal
(A) of heavy-duty, nonflammable material, into the
installation recess (see Fig. 1).
Insert deflector plate (B) in such a ay that the
hot air escapes through the air vent grating into
the open air.
Affix the discharge plate to the caravan all, not
to the refrigerator!
In addition, discharge plate (B) ith 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 ith a co l
(A). The co l (A) should ideally be affixed to the caravan
all, not to the refrigerator. Insert sealing strips at the bot-
tom 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. Ho ever the chosen method must prevent
draughts entering the living space of the caravan or motorhome. Failure to seal correct
ly ill allo arm air to collect around the refrigerator and its performance ill be
affected.
If the cavity bet een the caravan all 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 ithout 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

19
In this case, for gas operation, do not use the upper winter cover!
If even ith 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 allo ed 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 t o apertures in the caravan all.
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 lo er ventilation grating should be flush with the floor of the vehicle, allo ing 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 ith ire mesh or similar,
and an angle plate to protect it from stones, mud etc., the ire mesh must not reduce
the effective area of 13cm²
The ventilation gratings must have a free cross-sectional area of at least
250 cm2.
Dometic recommends using the L100/L200 ventilation and extraction system.
Comment:
If the distance bet een the all 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 t o
rectangles (451mm x 156mm) in the outer all
of the vehicle (for position of the cuts, see
point 6.3).
Securing the refrigerator
In the side alls of the refrigerator, there are four plastic sleeves ith scre s for
securing the refrigerator. The side alls or rails attached for securing the refrigerator
must be designed in such a ay that the scre s ill remain firmly in place even hen
under increased load ( hile 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
scre s into the all of the recess.
The scre s must penetrate through the sheet metal
casing of the refrigerator.
