Instructions for storing food in a refrigerator:

No refrigerator of any kind can improve the quality of the food; refrigerators can only maintain the food's quality for a short

duration as from the time of storing it.

Please observe the following particular conditions for storing food in a refrigerator that is built into a vehicle:

- A change in the climatic conditions such as temperature fluctuations

- High temperatures inside the vehicle when it is closed and parked in direct sunlight (temperatures are possible

up to 50°C)

- Use of the refrigerator whilst travelling with the power supply of 12V--DC

- A refrigerator built in behind a window and exposed to direct sunlight

- Storing the goods too soon, i.e. shortly after switching the device on for use

Under these particular conditions the refrigerator cannot guarantee having the temperature needed for food that perishes quik-

kly.

Foods that perish quickly include: all the products with a stipulated use-by date and a minimum storage temperature of +4°C

or less, especially for meat, poultry, fish, sausage, pre-packed foods.

Instructions

- Pack raw and cooked foods separately (e.g. in containers, aluminium foil, etc.)

- Only remove the outside packaging of single packs if all the necessary data, such as the use-by date, for

example, can also be read on the single packs.

- Do not leave cooled goods outside the refrigerator for too long.

- Place the foods with the next use-by date at the front, accordingly.

- Pack away any left-over food again and eat at the first opportunity.

- Wash your hands before and after touching any food.

main refrigerator compartment.

Gas faults

Remedies:

Set the energy selector switch (A) to position “OFF”.

1. Is there any gas in the gas bottle?

2. Is the gas bottle valve open?

3. Is the on-board shut-off valve open?

4. Set the main switch (A) to “on”

The reignition starts again.

If after about 30 seconds the operating display (C) starts flashing

again, the gas fault has not been cleared (e.g. air in the gas pipe).

5. Briefly switch the refrigerator off and then on again using main switch (A).

To remove air from the gas pipes, repeat this procedure 3-4 times.

If these actions do not help, please call the Dometic Service Centre.

5.2.3

5.2.4

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.

1. Set energy selector switch (A) to gas

2. Set rotary switch (B) to “MAX” postion.

the operating display (C) flashes yellow.

WARNING

Temperature setting cooling compartment

As shown, you are able to regulate the temperature of

the cooling compartment, if necessary, by turning

rotary knob (B) .

5.2.5

TTIIPP

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 require-

ments of the Climatic Class SN acc. to EN/ISO 7371 in the temperature range

of +10°C to 32°C ambient temperature.

5.3.1

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 tem-

peratures for a long period of time. This can cause the temperature in the free-

zer to rise and the stored goods to defrost.

WARNING

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 refrige-

rator.

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 hindran-

ce (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.

Positioning the storage rack

6.1.2

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 bur-

ner. Compared to side ventilation, this ven-

tilation 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.

Side installation with floor-roof ventilation

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.

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

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.5

Rear installation often causes an unfavou-

rable 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 performan-

ce of the aggregate is actually not availa-

ble.

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 exchan-

gers (condenser, absorber) cannot be ade-

quately cooled. The variant with an addi-

tional ventilation grille mounted in the floor

also has a bad airflow duct.

OK!!

Draught-free installation

The refrigerator must be sealed in such a way, that no air from the living area

can get to the gas burner and no draughts counter enter the living aera as well.

Proposal 1:

(Illustrated below are two typical approved methods of sealing.)

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, non- flammable material, into the

installation recess.

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 !

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 remo-

val 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 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

WARNING! DO NOT use any easily inflammable materials (in particular sili-

cone sealing agent or similar) for sealing! The device manufacturer's pro-

duct liability and guarantee shall lapse if such materials are used.

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 incorpor-

te 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.

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[2inch²]. 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 [2inch²] .

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 L100 / L 200 that has been tested and approved for this purpose.

Comment:

If the distance between the wall and the refrigerator is greater than 20mm [3/4”] the

gap can be reduced to 20mm [3/4”] by fitting a suitable baffle piece.

6.3

3/4”

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.
