INSTRUMENTS to scrape off frost or ice. Under no
circumstances should solid ice be forced off the ice box. Solid ice
should be allowed to thaw when defrosting the appliance. See
defrost instructions.

1. INTRODUCTION

Before starting to install the refrigerator, please read these
instructions carefully in order to obtain a thorough understanding of
what is required.

When operating, heat is emitted from parts of the cooling unit at the
rear and this has to be carried away by air circulating freely over the
back of the refrigerator. To ensure sufficient air circulation for

satisfactory operation. It is essential that the clearances called
for in these instructions are not reduced in any way otherwise
cooling performance will be impaired. Providing the refrigerator is

installed in accordance with these instructions, it should operate
satisfactorily in ambient temperatures up to 32°C (90°F), with some
measure of cooling up to about 35°C (95°F).

It is recommended that the refrigerator is installed by the caravan
manufacturer, the supplier or another qualified person Owners who
are competent to carry out the work themselves can do so, but, for
the sake of safety, they must take particular care in making the gas
connections, checking for leaks, and installing the electrical wiring
and fittings. All relevant regulations concerning such installations
must be complied with.

Many caravans are already provided with a recess, usually in the
form of a cupboard which has been specially designed so that it can
be adapted, by removal of its door and shelves, to house a
refrigerator. Some caravan manufacturers have also devosed kits of
parts to aid installation of refrigerators in their particular caravans.

A ventilator for fitting above the door as shown in fig. 4 is supplied
with the refrigerator. The connection pipe, gas cock, and connectors
are not supplied as the sizes of these may vary to suit particular
installations. The appropriate parts should, however, be readily
available from the refrigerator supplier or an Agent dealing in gas
fittings 9see note in item 11).

The refrigerator weighs approximately 14,5 kg (321b) and the surface
on which it is installed must be capable of carrying this weight, plus
that of the food, satisfactorily.

All surfaces above and adjacent to the flue outlet, and beside
and below the burner housing should be of, or covered with,
metal or other non-flammable material.

The appliance should be left for 2 hours after installation
before it is turned on in order to allow refrigerant to settle,
unless it is of the absorption type in which case it can be
turned on immediately.

This appliance is heavy. Care should be taken when moving
it.

Ice lollies can cause frost burns if consumed straight from the
freezer.

Frozen food must not be refrozen once it has thawed out.
Manufacturers' food storage recommendations should be

strictly adhered to. Refer to relevant instructions.
Do not place carbonated or fizzy drinks in the freezer as it

creates pressure on the container which may cause it to
explode resulting in damage to the appliance.

Under no circumstances should you attempt to repair the
appliance yourself. Repairs carried out by inexperienced
persons may cause injury or more serious malfunctioning.
Refer to your local Service Centre and always insist on
genuine spare parts.

GENERAL GUIDE TO FITTING ANY PLUG

Ensure the lengths of wire inside the plug are prepared
correctly.

Connections should be firmly made after all conductor strands
are entered into the terminal posts.

When preparing the cable ends take care not to damage the
outer sheath, or the insulation surrounding the inner
conductors.

Tighten all screws.
Replace the top cover of the plug and secure.

IMPORTANT: On motorised vehicles, the refrigerator must be
installed well away from fuel tanks, fuel filling inlets, pipes leading
from inlets to fuel tanks, and fuel tank breathers.

WARNING:
Because of the hazards associated with the use of continuous

operating bottled-gas appliances with open-flame burners in
difficult-to-ventilate confined spaces, and other considerations,
Dometic RT do not recommend the installation of their bottled-gas
caravan refrigerators on boats, and refrigerators so installed will
not be covered by the Company's guarantee.

If, however, a boat installation is planned for the refrigerator,
reference should be made to British Standard 5482 Part 3, 1979
and to the Thames Water Authority "Launch Digest" and "Launch
Specification".

Also, current Guide Lines published by local Water Authorities, or
the Ship and Boat Builders' National Federation.

It should be noted that special Marine Refrigerators are available
from Electrolux for use on boats.

2. VENTILATION

The refrigerator will always be built into a recess but to enable the
unit to operate efficiently, it is essential that air is allowed to
circulate freely over the cooling unit at the back to carry away the
heat generated during the cooling process 9see fig. 10. The
minimum free spaces called for under, behind and over the
cabinet must not, therefore, be reduced in any way. The more

space provided, particulary behind and over the cabinet, the
better the performance you can expect from the cooling unit.

IMPORTANT USER INFORMATION

It most important that this instruction book should be retained with the appliance for future reference. Should the appliance be sold or
transferred to another owner, always ensure that the book is supplied with the appliance in order that the new owner can be acquainted with
the functionning of the appliance and the relevant warnings.

These warnings are provided in the interest of safety. You must read them carefully before installing or using the appliance.

3. IMPORTANCE OF LEVELLING

The downward circulation of refrigerant within the cooling unit is by
gravity and the refrigerator has to be reasonably level, when it is
stationary, for the cooling unit to operate properly. If the refrigerator is
left operating with a sustained list in excess of about 3º in any
direction, pockets of liquid refrigerant can collect at various points
within the unit impairing or preventing normal circulation of the
refrigerant vapour until level conditions return.

It is essential, therefore, that the refrigerator is installed so that
the ice-tray shelf inside the refrigerator is level in relation to the
caravan, in both directions, so that when the caravan is level,
the ice-tray shlef is level.

4. CHANGING DOOR HINGES TO OPPOSITE SIDE

The refrigerator is manufactured with the door hinged on the right
hand side, however, it can be changed to left hand opening if
required.

Gently place the refrigerator on its back (taking care not to damage
the burner assembly0, pull off the gas control knob, then remove the
lower ventilator by taking out the screws from each end.

Remove upper hinge blade and travel catch blade from top of
cabinet. Fit the upper hinge blade and travel catch blade to their new
positions on the top of the cabinet and transfer the lower hinge blade
to the opposite side. Refit the ventilator by means of the screws, then
push the gas control knob onto its spindle so that the flat on the
spindle engages the flat in the recess of the knob.

5. CHANGING OUTER DOOR PANEL

If required, the outer door panel can be removed and replaced by one
of a different material or colour to match other fitments.

I can be of rust proof metal or plastic laminate.
To do this lay the refrigerator on its back, and remove the bottom

section of the door frame held by 3 screws. The existing panel can
then be slid out and a new panel slid in, and the bottom section
refitted to retain the new panel.

The replacement panel should be from 0,5 mm to 3 mm thick, and
350 mm wide x 485 mm high.

6. DIMENSIONS OF REFRIGERATOR

The exterior dimensions of the refrigerator are given in fig. 3.
For dimensions of the recess to house the refrigerator when building-

in, refer to item 7.

7. BUILDING-IN

While the refrigerator is built-in, adequate space must be left
under, over and behind it to allow a sufficient circulation of air over
the cooling unit at the back for satisfactory operation. The
recommended method of building-in is shown in fig. 5, with the
upper ventilator at the front. However, where space limitations do
not permit the upper ventilator to be fitted at the front, the
alternative arrangement shown in fig. 6 may be adopted and the
height of the recess reduced accordingly. A work-surface can
then be fitted over the top front of the refrigerator, but it must not
over-hang the door where it could interfere with the operation of
the travel catch.

Securing in the Recess

The refrigerator must be secured in the recess to prevent
movement. A suggested method of securing is by means of metal
brackets about 20 mm (3/4") wide, (which should be made to suit
the particular installation), screwed to the rear of the refrigerator
by means of the two existing cooling unit fixing screws (fig. 2) and
to the rear wall of the caravan

9. FLUE ARRANGEMENT

Flue Baffle

The flue baffle (4, fig. 10) must be in position in the central tube
of the boiler, suspended on its support wire so that the lower end
of the baffle is 75 mm (3") above the bottom of the central tube
over the burner. The top end of the baffle support wire is bent into
the shape of an "O" and rests horizontally on the tp of the central
tube. The baffle is correctly positioned during the manufacture
ans should not become displaced during normal use. If the flue
baffle is missins or is incorrectly located, the cooling unit will not
operate properly on gas. Any strapping tape used to retain the
baffle support wire to the top of the boiler casing during transit
should be removed before installation.

Flue Venting Kit

The flue gasses must be vented directly to the outside air. Only
the flue venting kit (supplied with the refrigerator in the United
Kingdom) is recommended for this purpose. It consists of the
following parts:

Flue Top Complete-G
Flue Outlet Cover Plate-B
Exhaust Gas Pipe Complete-F
Screw-sELF tAPPING. nO. 6 X 1/4in-H
The flue top (G) is in the form of a lazy "T" and incorporates an

air-break to minimise the possibility of flame extinction due to
draughts.

Leading from the flue-top, the extension tube (F) has to pass
through the wall of the vehicle to direct the flue gasses to the
outside. Care must be taken in determining the positions of the
centres of the holes in the inner and outer skins of the caravan
wall to accept the extension tube. As the amount of space
between the back of the refrigerator and the inside wall og the
vehicle as well as the thickness of the wall, may vary for each
type of caravan, it is not possible to give actual dimensions
therefore each case must be considered carefully before starting
to make the opening. Take particular care to ensure that the angle
is correct so that when in position, the extension tube will line up
accurately with the sloping part of the flue-top.

The opening mus be large enough to allow the insertion of a layer
of non-combustible material around the extension tube as shown
in fig. 7, but the opening in the outer skin must not exceed 70 mm
(2 3/4") in diameter, otherwise the flange on the flue outlet may
not cover it completely.

4

Alternatively, wooden battens may be screwed to the sides of the
recess, from front to back, bearing down on the top of the cabinet to
hold it firmly, as shown at A, fig. 4. Whichever method is used, it must
be possible to remove the refrigerator easily for subsequent servicing
purposes. The brackets or battens must be in a position where they
will not restrict the air circulation over the cooling unit; they must not
be positioned across the cabinet over the fins of the condenser of the
cooling unit at the rear, otherwise air-flow will be impaired and
performance affected.

Fitting the Upper Ventilator

To fit the upper ventilator, screw a block of wood approx. 25 mm (1")
square x 66 mm (2 5/8) long. to each side of the recess, 16 mm (5/8")
back from the front edge, as shown at B, fig. 4. Secure the ventilator
to the blocks with a screw through the hole provided at each end.

Additionnal Ventilator

To reduce the amount of heat entering the caravan, particularly when
used in warner climates, an additionnal ventilator (A, fig. 5), may be
fitted in the wall of the vehicle, preferably above the level of the top
of the refrigerator. (The exterior flue venting kit must still be used).

All surfaces above and adjacent to the flue outlet, and beside and
below the burner housing should be of, or protected by, metal or
other inflammable material.

8. VENT HOLE UNDER REFRIGERATOR

A ventilation hole of not less than 13 cm2 (2in2) effective area (40
mm or 1 5/8" diameter) must be provided in the floor below the
refrigerator as shown in fig. 5. The hole should lead directly to the
outside air through the floor or wall so that, in the event of a gas leak,
it would provide an escape outlet for the heavier-than air gas. It
should not be too close to the burner where draught could affect the
flame.

On mobile installations, the vent hole should be shielded against
entry of mud etc., by a deflector as shown in fig. 5a, fitted underneath
with its "closed" end facing the front of the vehicle. The deflector
should be made from a suitable piece of metal, to suit the particular
installation.
