The refrigerator must be operated using liquid gas (propane, butane) (no natu­ral gas or town gas).

When using LPG gas, please consider that the burner needs cleaning at

shorter intervals due to the gas combustion method (2 - 3 times per year

recommended.
In Europe, gas operation is permitted while travelling only on the condition that

the gas system of the vehicle is equipped with a hose rupture protection. The
national regulations of the respective country must be observed.

For physical reasons, gas ignition faults could occur starting from an altitude
above sea level of approx. 3280 ft. / 1000 m (No malfunction!)

AUTO”-operation

RM7XX5 L - models are equipped with an “AUTO”-MATIC function.

Explanations:

Upon switching on, the electronics automatically select one of the three
possible energy types: 230V - 12V - liquid gas. The control electronics
automatically ensure that the refrigerator is supplied with the optimum
source of energy in each respective case.

Priority 1.) Solar (12V DC)

2.) 230V AC

3.) 12V DC

4.) Liquid gas

The selected energy is displayed by the corresponding LED (i.e. 230V)

.

230 V - operation

If sufficient supply voltage is available (more than 200V), this power source is

selected as the first option ( no solar-system installed).

12 V - operation

12V operation should only be selected while the vehicle motor is running or there
is sufficient voltage available from the solar system. This can be detected from
the D+ connection of the alternator to the electronics, or from the respective sig­nal on the solar charge regulator.

Gas operation

Gas operation is selected in the following circumstances:

 No supply voltage available.
 The vehicle engine is not running.
 Supply voltage less than 200V

Gasfaults at “AUTO” - mode see “5.2.4”

Manual operation is possible at any time.

5.2.5

The use of naked flames is prohibited in petrol station environments. If the
refuelling stop lasts longer than 15 mins., the refrigerator should be swit­ched off at the main switch (A), or switched over to another energy type.

In order to prevent unintended switching to gas operation during refuel­ling, the electronic system starts gas operation of the refrigerator, after the
motor has been turned off for 15 mins. During this time the appliance is in
stand-by operation mode and only the "AUTO" LED lights up.

TIP

medium setting

The cooling unit’s performance is influenced by ambient temperatures.
Please select the medium setting for ambient temperatures between +15°C

and +25°C. The unit operates within its optimum performance range..

5.3

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.

Storing food

General advices

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") .

Making ice cubes

Ice cubes are best frozen overnight. At night, the refrigerator has less work to do and
the unit has more reserves.

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 5.8 - "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.

5.3.2 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.

Maintenance

 Works on gas components and electrical installation may only be carried out

by authorised personnel. We recommend to contact your Dometic Service
Centre.

 EN 1949 stipulates that the appliance´s gas equipment and it’s associated fume

system must be inspected after installation and a certificate issued.
Afterwards a qualified technician must inspect according to EN 1949 every two

years and a certificate issued.

It is the user’s responsibily to arrange for inspections after purchase.

 It is recommended that the gas burner be inspected and cleaned as necessary at

least once a year.

We recommend maintenance following an extended shutdown of the vehicle.

Product liability

Product liability of Dometic GmbH does not include damages which may arise from
faulty operation, improper alterations or intervention in the equipment, adverse
effects from the environment such as changes in temperature and air humidity, which
may impact the equipment itself or the direct vicinity of the equipment or persons in
the area.

Environmental hints

Refrigerators manufactured by Dometic GmbH are free of CFC/HCFC and HFC.
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.

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.

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:



The electrical installation must comply with national regulations.



Technical regulations EN 60335-1, EN 60335-2-24, EN 1648-1, EN 1648-2



The gas installation must comply with national regulations.



Technical regulations EN 1949



Technical regulations EN 732



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 (fig. 1, gap between
door and vent grille min. 25 mm). Otherwise ventilation could be impaired which cau
ses 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 venti
lation grilles (loss in cooling performance)!

6.1.1

(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 per-

formance in high ambient temperatures.

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

Side installation with floor-roof ventilation6.1.2

6.1.3

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.

The maximum cooling performance is not
available!
Please assure at all the installation varia­tions correct ventilation and extraction, as
described in item 6.3!

Fig.4

Fig.5

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.

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.

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.

Draught free installation

Refrigerators in motorhomes, caravans or other vehicles must be installed in a
draftproof manner (EN 1949). This means that the combustion air for the burner is
not taken from the living area and that exhaust fumes are prevented from entering the
living area .

In no case, use sealing material or foam, in order to build in the fridge
draught-free.

Proposal 1:

Using sealing lips

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 heavy­duty, non- flammable material,
into the installation recess (see
Fig. 4).

Insert deflector plate (B) in such a way that the hot
air escapes through the air vent grille into the open
air. Affix the discharge plate to the caravan wall, not

to the refrigerator !

Ensure that the refrigerator is
installed level in the recess.

Proposal 2:

Using a frame

Another option is to provide the refrigerator with a frame
(A). The frame (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 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 cara
van 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 (LS 200), and that the T-piece
of the flue pipe is turned 45 degrees towards the outer wall.

6.2

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.

WARNING !

21

In this case, for gas operation, do not use the upper winter covering!

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 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.
Should this arrangement prove impossible, a ventilation aperture must be introduced
by the manufacturer of the vehicle into the recess floor intended for the unit's installa­tion, in order to avoid the accumulation, on this floor, of any non-combusted gas which
might escape.

The ventilation grilles must have an open cross-section of at least 250cm².
This is reached using the Dometic Absorber Ventilation and Air Extraction
System LS 100 / LS 200 that has been tested and approved for this purpose.

Comment:

If the distance between the wall and the refrigerator is greater than 20mm the gap
can be reduced to 20mm by fitting a suitable baffle piece.

6.3

Deviations shall require the consent of the manu­facturer.

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

Installation recess

The refrigerator must be installed draught-free in a recess (see point “6.2”).
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.

Recess measurements:

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.
