Gas operation
The refrigerator should only be operated using liquid gas
(Propane, Butane). Do not use Autogas, town gas or natural gas.
If the refrigerator is operated during travel using gas, the precautions
stipulated by the legislation in the respective country must be taken (in
conformity with the European standard EN 732).
Due to physical reasons, ignition faults could occur starting from an
altitude above sea level of approx. 1000 m /3280 ft. (No malfunction!)
As a basic rule, operation using gas is prohibited in petrol stations.
All refrigerators, whether manual or automatic ignition, are equipped
with automatic flame protection, which automatically cuts off the supply of gas approximately 30 seconds after the flame goes out.
When using for the first time, and after changing the gas cylinder, the
gas pipes may contain air. By means of brief operation of the refrigerator and any other gas appliances (e.g. cookers), air is removed from
the gas pipes. The gas will ignite without delay

Dometic refrigerators work according to the absorption principle.
Due to physical reasons, an absorption system responds slowly to changes
made on the thermostat controller, or a loss in cooling through opening the
door, or storing food. The devices fulfill the cooling performance requirements of the Climatic Class SN acc. to EN/ISO 7371 in the temperature
range of +10°C to 32°C ambient temperature
5.2.5
Exchange of the igniter’s battery
Unlock the battery by depressing and turning the button (C) approx. 90° clockwise.

5.3.1
Storing food
General advices
5.3.2
Switch the refrigerator on approx. 12 hours before filling it.
Always store pre-cooled foods in the refrigerator. Make sure that the food is well
cooled when it is bought and also when transporting it. Use insulated cooling bags.
When taking food out of the refrigerator only open the refrigerator door very briefly.
Foods must be packed - best of all in closed containers - and stored separately from
each other.
Allow foods that have been warmed up to cool down before storing.
Products that could emit volatile, flammable gases must not be stored in the refrigerator.
Store quickly perishable foods directly next to the cooling fins.
The refrigerator must not be exposed to direct sunlight. Please bear in mind that the
tem- perature inside a closed vehicle increases sharply if exposed to sunlight and that
this can reduce the efficiency of the refrigerator..
The air around the cooling unit MUST be able to circulate freely without any hindrance
(see also section 6.3 "Ventilation and air extraction") .
Freezer compartment
Do not keep carbonated drinks in the freezer.
The freezer compartment is suitable for making ice cubes and for short-term
storage of frozen food. It is not suitable as a means of freezing foods.
When ambient temperatures are lower than +10°C an even regulation of freezer
temperature cannot be guaranteed, if the refrigerator is exposed to these temperatures for a long period of time. This can cause the temperature in the freezer to rise and the stored goods to defrost.
9
5.4
Making ice cubes
Ice cubes are best frozen overnight. At night, the refrigerator has less work to do and
the unit has more reserves.
1. Fill the ice
cube tray with
drinking water.
2. Place the ice cube tray
in the freezer
compartment.
Only use drinking water!
5.5
Defrosting
As time goes by, frost builds up on the fins.
When the layer of frost is about 3mm thick, the refrigerator should be defrosted.
1. Switch off the refrigerator, as described in Section 5.7 - "Switching off".
2. Remove the ice cube tray and food.
3. Leave the refrigerator door open.
4. After defrosting (freezer compartment and fins free of frost), wipe the cabinet dry
with a cloth.
5. Use a cloth to mop up the water from the freezer compartment.
6. Switch the refrigerator back on again.
The layer of ice must never be removed forcibly, nor may defrosting be
accelerated using a heat source.
Note:
Water thawing in the main compartment of the refrigerator runs into an appropriate
container at the back of the refrigerator. From there, the water evaporates.
5.6
Positioning the storage rack
Dismantling:
2.
1.
1. Loosen the front
and back securing
brackets.

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
EN 1949 for liquid gas units in vehicles.
6.1
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:
European Standard EN 1949
European Standard EN 732
The electrical installation must comply with national regulations
( EN 1648-1 , EN 1648-2 , EN 60335-1, EN 60335-2-24 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.
Any installation that is not carried out by qualified persons will
jeopardize the manufacturer's guarantee.
6.1.1
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. 1, gap between door
and vent grille min. 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 discharge of combustion gases and heat through the ventilation grilles (loss in cooling performance)!

OK!
(Fig.1) Air vent grille 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 25mm and 45 mm, we recommend installing a
Dometic ventilation kit (spare part no. 241 2985 - 00/0) to achieve an optimal cooling performance in high ambient temperatures.

6.1.2
Side installation with floor-roof ventilation
It is also possible to perform ventilation of
the refrigerator via an aperture in the floor
and a roof ventilation (see fig. 3). A flue
has to be provided between the top edge
of the refrigerator and the roof ventilation
which directs the hot air and the exhausts
straight to the air vent in the roof.
hot air
The opening in the floor must have a cross
section of at least 250cm². Protect the
opening, e.g. with a baffle plate and a net,
to prevent dirt from entering the gas burner. Compared to side ventilation, this ventilation method can allow more dirt to enter
the rear area of the refrigerator, which
makes regular maintenance of the gas
burner, at least once a year, necessary.
condenser

floor opening:
at least 50 mm wide
at least 520 mm long
With this method of installation regular maintenance of the gas burner is only
possible once the device has been dismantled. The refrigerator has to be
installed in a way allowing easy dismantling.
6.1.3
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!)
(Fig. 4). The maximum cooling performance of the aggregate is actually not available.
Another variant of the rear installation is
the side installation of the ventilation grilles
(fig. 5). The air-heat recirculation is very
restricted which means the heat exchangers (condenser, absorber) cannot be adequately cooled. The variant with an additional ventilation grille mounted in the floor
also has a bad airflow duct.

Please assure at all the installation
variations correct ventilation and

6.2
Draught-free installation
The refrigerator must be sealed in accordance with EN 1949.
Illustrated below are two typical approved methods of sealing.
Do NOT use any easily inflammable materials (in particular silicone sealing
agent or similar) for sealing! The device manufacturer's product liability
and guarantee shall lapse if such materials are used.
Proposal 1:
Using the Installation Sealing Kit from Dometic
(SP.No. 241 2559-00, available from Dometic)
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.
Fig.1
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 refrigera
tor 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.
20
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.
Deviations shall require the consent of the
manufacturer.
6.3
Ventilation and air 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
vent grille.
The upper ventilation grille should be positioned as
high as possible above condenser (A).
The lower ventilation grille 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 ( EN
1949).
The ventilation grilles must have an open crosssection of at least 250 cm². This is reached using
the Dometic Absorber Ventilation and Air
Extraction System L100 / L 200 that has been
tested and approved for this purpose.

Installing the ventilation 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.
Correct mounting of the lower ventilation grille facilitates the access
to the electrical and gas connections during maintenance work.

6.5
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.

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.
23
6.7
Fume extraction
Fume extraction must be arranged in such a way as to provide complete
extraction of all products of combustion to an area outside the living area.
The flue system must slope in an upward direction in order to avoid a
build-up of condensation.
An installation that is not carried out by qualified persons causes a
reduction in the cooling capacity and will jeopardize the
manufacturer's guarantee.

6.8
Gas installation
The rules in point 6.1 must be adhered to.
When running on gas, these appliances are intended exclusively to use
liquid gas (propane/butane) - under no circumstances should town gas or
natural gas be used (EN 27418).
A fixed, pre-set pressure regulator complying with EN 12864 must be
connected to the liquid gas cylinder.
The pressure regulator must concur with the operating pressure specified
on the data plate of the appliance. The operating pressure corresponds to
the standard pressure of the country of specification (EN 1949, EN 732).
Only one connection pressure is permissible for any one vehicle. A plate
showing the permanent, clearly legible notice must be displayed in full view
at the point where the gas cylinder is installed.
The gas connection to the appliance must be installed securely and at
zero potential using tube connectors and must be securely connected to the
vehicle (a hose connection is not permissible) (EN 1949).
Inflamable material should not be in immediate proximity to the burner.
25
The gas connection to the appliance is effected by means of a suitable
coupling tube fitting L8, DIN 2353-ST, complying with European Standard
EN 1949 (e.g. Ermeto).
The gas connection may only be carried out by a qualified personnel.
SW 14
SW 17
Following proper installation, a testing for
leakage and a flame test must be carried
out by *qualified personnel in compliance
with EN1949 .
A certificate of testing must be issued.
* qualified personnel
Qualified personnel are accredited experts who
are able, by virtue of their training and knowledge,
to vouch for the correct implementation of the leakage test.
The refrigerator must be equipped with a
gas cock (C) in the supply line to allow the
supply to be disconnected. Such a cutout
device must be readily accessible to the user.
