4.0 Installation instructions
The unit and the exhaust duct system must be
in principle installed so that it is accessible for
maintenance work, can be easily installed and
dismantled and removed from the vehicle without great effort.
Installation and connection of the appliance
must comply with the latest technical regulations, as follows:
The electrical installation must comply
with national and local regulations.
The gas installation must comply with
national and local regulations.
European Standards EN 1949
European Standards EN 60335-1,
EN 60335-2-24, EN 1648-1 , EN 1648-2
The appliance must 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!
4.1 Installation
Deviations from these installation instructions without prior notification of Dometic
result in Dometic GmbH's warranty obligations becoming void!
The appliance may be installed by authorised personnel only!
WARNING!
(Fig. 4 )The air vent grilles offer an unobstructed dissipation of heat and exhaust gas even
when the door is opened.
4.1.1 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. (Fig. 3, Clearance door/ventilation grille
at least 25 mm). Otherwise ventilation could
be impaired which causes a loss in cooling
performance. Awnings are often placed at the
door side of a caravan. This complicates evacuation of combustion gases and heat through
the ventilation grilles (loss in cooling performance)!
(Fig. 3) The air vent grilles are blocked. There
must be a distance between the door and the
air vents of at least 25 mm!
If the door/grille distance is between 25 mm
and 45 mm, we recommend installing a
Dometic ventilation kit
(item no. 241 2985 -
00/0)
to achieve an optimal cooling perfor-
mance in high ambient temperatures.
10
Installation
Another unfavourable method of rear installation is to install the air intake and exhaust grilles (Fig. 6) at the side wall of the recreation
vehicle. The air-heat recirculation is very
restricted which means that heat exchangers
(condenser, absorber) cannot be adequately
cooled. The optional method of an additional
air vent grille installed in the floor also exhibits
an insufficient air flow duct.
Fig. 5
Air vent grille
not blocked!
OK!
4.1.2 Rear installation
Rear installation often causes an unfavourable
installation arrangement, as ideal ventilation
cannot always be assured (e.g. the lower ventilation grille is covered by the bumper or the
rear lights of the vehicle!). The maximum cooling performance of the aggregate is actually
not available.
The maximum cooling performance is not
available! Do not apply this installation
method, as it does not provide proper ventilation! Please refer to the description in
section 4.2.
CAUTION!
Fig. 6
4.1.3 Draught-proof installation
Refrigerators in motorhomes, caravans or
other vehicles must be installed in a draughtproof manner (EN 1949). This means that the
combustion air for the burner is not taken from
the living space and that exhaust fumes are
prevented from entering the living space.
Adequate sealing between the back of the
refrigerator and the vehicle interior has to be
provided.
Dometic strongly recommend using a flexible
sealing for this purpose (temperature-resi-
stant up to 200 °C in the area of the oven),
in order to facilitate future removal or installation of the appliance during maintenance
By no means use durable sealing compounds, fitting foam or similar material to
realise draught-proof installation of the
refrigerator ! Do NOT use any easily
inflammable materials for sealing (in particular silicon sealing compound or similar).
Risk of fire! The device manufacturer's
product liability and warranty shall lapse if
such materials are used.
WARNING!
The lip seals (1) are installed at the bottom and
on each side in the installation recess (Fig. 7-
9). A heat deflector plate (2) is installed in the
installation recess above the refrigerator. Affix
this plate to the caravan wall, do NOT
attach to the refrigerator !
11
Installation
Deviations shall require the consent of the
manufacturer.
Fig. 8
Fig. 7
Fig. 9
Fig. 10
Attach the deflector plate so that the heated
air escapes through the top ventilation grill into
the open air and no heat build-up can be produced.
The refrigerator is later pushed into the installation recess from the front. Ensure that the
seals abut the case evenly.
This installation option facilitates the removal
and installation of the appliance for servicing.
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. The
waste gases escape to the outside through
the upper grill of the ventilation. Do not use
any kind of aluminium flue pipe to lead the flue
gas out.
Fasten the sealing lips to a stop bar on the
rear side (1), e.g. by gluing.

The refrigerator must be installed draughtproof in a recess (also refer to Section "4.1.3").
The measurements of the recess are stated in
the table below. Push the appliance far
enough into the recess until the front edge of
the refrigerator casing is aligned 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. Install a removable screen / grill
above the oven (for fixing and removing of flue
outlet).
Ensure that the refrigerator is installed level
in the recess.

Installation

In the event of high ambient temperatures,
full performance of the cooling unit can
only be achieved by means of adequate
ventilation and extraction.
A correct installation of the refrigerator is
essential for its correct operation, as due to
physical reasons heat builds up at the back of
the appliance which must be allowed to escape into the open air.
If ventilation and exhaust duct into the vehicle
is intended, fresh air supply must not be
obstructed. The room in which the device is
installed must have one or several openings
allowing fresh air to enter (safety ventilation
according to EN 721). These openings must
have a total cross section of at least 100
cm². There must be one or several ventilation openings above the device with minimum cross sections of 150 cm². These have
to be checked and if necessary cleaned regularly. Roof and wall outlet openings can be
combined. Lower ventilation openings must
be no more than 100 mm above the inside
floor. The ventilation openings must by no
means be shut. Grilles and covers must be
kept clean and free of dust.

4.3.2.1 Ventilation to vehicle's interior
(special equipment, model without

(for ventilation to the vehicle’s interior)
Ventilation is provided for the unit by means of
two apertures (ventilation grilles) in the caravan wall. Fresh air enters at the bottom,
extracts the heat and exits through the upper
vent grille (chimney effect). The upper venti-
lation grille should be positioned as high as
possible above the cooling unit (Fig. 11).
Install the lower ventilation grille at floor
level of the recess floor (Fig. 16), allowing
unburnt gas (heavier than air) to escape directly into the open air. The gas burner must be
located above the edge (1) ..
Should this arrangement prove impossible,
a ventilation aperture must be introduced
by the manufacturer of the vehicle into the
recess floor in order to avoid the accumulation of unburnt gas on the floor.
The ventilation grilles must have an open
cross-section of at least 400 cm². This is
achieved by using the Dometic LS 300 absorber ventilation and air extraction system
which has been tested and approved for this
purpose.
