OPERATING INS TR UCTIONS
CONTROLS
The refrigerator can be run on either 230 V, 12 V or LP gas.
Changing between these modes of operation is carried out
by means of the controls of the control panel shown in fig 3.
Two rocker switches are used to select the electric power
supply, one for 230 V
(B) and one for 12 V (A).
Refrigerator temperature
is controlled by a thermostat (C)
when the unit runs on 230 V. The gas supply is turned
on/off
by means of the knob (0). When lighting the gas, one
must press
in the knob as explained further on.
Refrigerator temperature
is controlled by a thermostat (E)
when the refrigerator runs on LP gas. Please note that the
thermostat has
no position.
In model RM 4271 , the gas flame is electronically lit, moni-
tored and relit
if necessary. For this the toggle switch (F)
should on" during gas operation.
An indicator lamp in the switch flashes when the automatic
igniter attempts
to light the burner. Otherwise this lamp is
off.
In model RM 4270 a manual piezo-eletric igniter is used.
When the button
(G) is pressed, sparks are generated at
the burner.
Inside the refrigerator at bottom left is a sight glass for the
burner. A blue light can
be seen through it when the flame
is alight. (RM 4270)
STARTING THE RE FRIGERATOR
Caution!
Only use one source of energy at a time
The position numbers refer to fig. 3.
LP Gas operation
After initial installation, servicing, or changing gas cylinders
etc., the gas pipes may contain some air which should
be
allowed to escape by briefly turning on the refrigerator or
other appliances. This will ensure that the flame lights
immediately.
To start gas operation:
1. Open the shut-off valve of the gas bottle (check that there
is enough gas). Open anyon-board shut-off valve.
2. Check that the switches for mains and 12 V operation are
off.
If you have Model RM 4271 proceed as follows:
3. Turn on the gas supply by pressing the (0) knob and
turning
it to the position
4. Set the thermostat knob (E) to the highest setting.
5. Depress switch (F). A light in the switch should now start
to flash, indicating that sparks are being generated at the
burner.
6. Press the (0) button. This opens the flame failure device
and allows gas
to flow to the burner.
7. When the flame lights, the sparking stops automatically
and the switch stops flashing.
8. Keep the (0) button pressed for a further 10 to 15 secon-
ds
to active the fl a me failure device, then release it.
If you have Model RM 4270 proceed as follows:
3. Turn on the gas supply by pressing the (0) knob and
turning
it to the position
4. Set the thermostat knob (E) to the highest setting.
5. Keeping the flame failure device buttom (0) pressed,
operate the igniter
(G) until the flame lights.
6. Keep the (0) buttom pressed for a further 10 to 15 se-
conds then release
it.
The flame can be observed in a wiewing glass inside the
refrigerator at the bottom left (RM4270).
To terminate gas operation, turn knob (0) to and (when
applicable) set switch
(F) to
230 V Operation
e Turn off gas or 12 V operation when applicable.
e Turn the knob (C) of the thermostat to its highest (col-
dest) position.
e Set switch (B) to position I. The switch will light up green
when the power supply
is connected.
12 V Operation
Only operate your refrigerator on 12 V when the engine of
the vehicle
is running -otherwise your battery will soon be
discharged.
e If applicable, turn off the gas operation.
e Set the 12 V rocker switch (A) to I. The switch will light
up red when the power supply is connected.
WINTER OPERATION
Please check th at the ventilation grilles or the flue outlet are
not blocked by snow, leaves etc.
ELECTROLUX ventilation grilles A 1620 (fig 2), can be
fitted with winter covers, model WA 120, to protect the
cooling unit against cold air. The covers may
be fitted when
the outside temperature
is below approx. and should
be fitted when the temperature is below the freezing point.
We suggest that you fit the winter covers also
in the case
that the vehicle
is laid up during the winter months.
REGULATING THE TEMPERATURE
The position number refers to fig. 3.
It will take a few hours for the refrigerator to reach normal
operating temperature. So
we suggest you start it well in
advance of a trip and if possible store it with precooled
foodstuffs.
On 230 V operation the refrigerator is controlled by a ther-
mostat and the thermostat knob (C) should
be set at 3-5. If
a lower (colder) temperature
is desired, set the thermostat
to a higher figure.
On 12 V operation the refrigerator works continuously.
On LP gas operation the refrigerator temperature is regula-
ted
by the gas thermostat (E), which should be set at 3-5 If
a lower (colder) temperature
is desired, set the thermostat
to a higher figure.

TRAVEL CATCH
Make sure that the travel catch is engaged when the cara-
van
is on the move, (fig 1) .
The travel catch
at the top of the door can be set in two
different positions.
In one position the door is held tightly
shut.
In the other position the door is secured ajar so that
the refrigerator can
be aired when not in use.
FOOD STORAGE
Always keep food in closed containers. Never put hot food
in the refrigerator; allow it to cool first.
Never keep items in the refrigerator which might give
off flammable gases.
The 2-star (**) frozen food compartment is intended for the
storage of frozen food and for making ice.
It is not suitable
for freezing items of food.
Never put bottles or cans of fizzy drinks
in the frozen food
storage compartment as they may burst when freezing. Also
don't give children ice lollies straight from the frozen food as
they could cause frost burns.
Most kinds of frozen food can
be stored in the frozen food
compartment for about a month. This period of time may
vary, however, and
it is important to follow the instructions
on the individual packets.
ICE MAKING
It is practical to make ice during the night -then the refrige-
rator
is less demanded and the cooling unit has more reser-
ves. Fill the ice tray
to just below the brim with drinking
water and place
it on the freezer shelf.
To speed up the ice making, one can spill one or two
spoonfuls of water
on the freezer shelf to improve the con-
tact
to the ice tray. If you have more than one ice tray it is a
good idea
to make ice in advance and save the frozen trays
in the frozen food compartment.
DEFROSTING
Frost will gradually accumulate on the refrigerating sur-
faces.
It must not be allowed to grow too thick as it acts as
an insulator and adversely affects refrigerator perfor-mance.
Check the formation of frost regularly every week and when
it gets about 3
mm thick, defrost the refrigerator.
To defrost the 'fridge, turn
it off and remove the ice tray and
all food items. Warning: normally the temperature of items
of fozen foods would rise unduly during defrosting and so
they should
be consumed within 24 h or discarded.
Do not try to accelerate defrosting by using any kind of
heating appliance, as this might damage the plastic sur-
faces of the refrigerator. Neither should any sharp objects
be used
to scrape off the ice.
The defrost water runs from a collector channel
to a recep-
tacle at the rear of the refrigerator where
it evaporates.
Defrost water
in the freezer compartment should be mop-
ped up with a cloth.
When the ice has melted, wipe the refrigerator dry and
restart
it. Place the food items back inside but wait until the
refrigerator
is cold before making ice cubes.
CLEANING THE REFRIGERATOR
Clean the inside of the refrigerator regularly to keep it fresh
and hygienic.
Soak a cloth
in a solution consisting of a teaspoon of bicar-
bonate of soda
to half a litre of warm water. Wring out the
cloth and use
it to clean the interior of the refrigerator and
its fittings.
Never use detergents, scouring powder, strongly scented
products or wax polish
to clean the interior of the refrigera-
tor as they may damage the surfaces and leave a strong
odour.
The exterior of the refrigerator should
be wiped clean now
and again, using a damp cloth and a small quantity of deter-
gent. But not the door gasket, which should only
be cleaned
with soap and water and then thoroughly dried.
TURNING OFF THE REFRIGERATOR
If the refrigerator is not to be used for some time:
1. Set any switches
to O.
2. Set the gas valve (D) to •.
3. Shut off anyon-board valve in the gas line to the refrige-
rator.
4. Empty the refrigerator. Defrost and clean
it as described
earlier. Leave the doors of the refrigerator and the frozen
food compartment ajar. Use the travel catch
to hold in
this position.
5. When the vehicle is laid up for a long period of time
(e.g. during the winter months),
we suggest fitting the
winter covers WA 120, fig.
2, onto the vent grills.
IF FRIDGE FAILS TO WORK
Check the following points before calling a service
technician:
1. That the STARTING THE REFRIGERATOR instructions
have been followed.
2. The refrigerator is level.
3. If it is possible to start the refrigerator on any of the
connected sources of energy.
4. If the refrigerator fails to work on gas, check:
• That the gas bottle
is not empty.
• That all Lp-gas valves are open.
5. If the refrigerator fails to work on 12 V, check:
• That the
12 V supply is connected to the refrigerator.
• That the fuse
on the 12 V supply is intact.
• That the 12 V switch
is on.
6. If the refrigerator fails to work on 230 V, check:
• That the 230 V supply
is connected to the refrigerator.
• That the fuse
is intact.
If the refrigerator is not cold enough it may be because:
1. The ventilation is inadequate owing to reduced area of
the ventilation passages (partial blockage of grilles from
wire mesh etc).
9

2. The evaporator is frosted up.
3. The temperature control setting is incorrect.
4. The gas pressure is incorrect check the pressure regu-
lator at the gas container.
5. The ambient temperature
is too high.
6. To much food
is loaded at one time.
7 . The door
is not properly closed or the magnetic sealing
strip
is defective.
8. More than one source of energy is used at the same
time.
If the refrigerator still does not work properly, call a
service technician.
The sealed cooling system must not be opened, since
it is under high pressure.
MAINTENANCE
Concerning gas- and electric installations, only authorized
experts are allowed
to carry out maintenance and repair
works. Besides,
it is recommendable to contact an authori-
zed service
if it comes to repair works.
According
to the valid regulations G607 of DVGW, the gas
installation as well as the connect flue oulets are
to be
checked every two years by an expert (this has to be
arranged by the person responsible).
SOME USEFUL HINTS
Make sure that:
• The refrigerator is not operating on 12 V when the ve-
hicle
is parked, otherwise you will drain the car battery in
a short time.
• Defrosting is carried out periodically.
• The refrigerator is left with the door(s) ajar when
it is not
to be used for some time.
• Liquids or items with a strong odour are well packaged.
• The ventilation openings are unobstructed.
• The door
is secured by means of the travel catch when
the caravan
is on the move.
• Only one mode of operation at a time
is used to run the
refrigerator.

-
• Remove the lower trim moulding and then withdraw the
panel by sliding
it downwards.
• Fit new panel
in place and slide it up as far as possible.
• Fit the trim moulding back
in place.
BUILDING-IN
The refrigerator is intended for in stallation in a caravan or
motorhome, and the description relates to this application.
The refrigerator must not
be exposed to radiated heat from
hot objects (e.g. below a cooker without proper heat shiel-
ding).
Excessive heat irradiation impairs performance and leads to
increased energy consumption. For this reason the refrige-
rator should
be installed if possible not at the entrance side
of the vehicle -normally orientated south and often with an
awning which would impair the dispersion of heat and
combustion gases from the ventilation openings.
It is not a good practice to install the refrigerator so that the
vent openings are covered
by the vehicle's entrance door
when this is open. This would reduce the ventilation air
fl ow
to the cooling unit and reduce refrigeration performance.
The enclosure
The refrigerator must be installed in an enclosure, the
dimensions of which are shown
in TECHNICAL DATA.
The bottom of the enclosure must be horizontal and even
so that the refrigerator can be easily pushed into place. It
must be sturdy enough to carry the wieght of the refrigera-
tor.
Battens must
be installed at the enclosure and fitted with
sealing strips, as shown
in fig. 4.
Slide
in the refrigerator until it is flush with the front of the
recess. There must
be 10-20 mm free space behind the
refrigerator.
Four fasteners are fitted
in plastic bushings in the side walls
of the fridge, fig.
7. They are used for securing the refrigera-
tor
in the enclosure.
The side walls of the enclosure and/or any wooden braces
installed to hold the refrigerator must
be dimensioned to
seat the screws secure
ly, also considering the forces due to
the movement of the vehicle.
With the refrigerator
in place, drive the screws through the
bushings
in the lining of the refrigerator into the walls of the
enclosure (fig.7). There must not
be more than 3mm of
clearance between refrigerator and enclosure
on each side.
If necessa ry, wooden strips or similar should be fitted.
Note: This is the only approved means of securing the
refrigerator
to the enclosure and to the vehicle. Fasteners
penetrating other parts of the insulation (PU) foam of the
refrigerator might damage components like electric wiring
etc.
VENTILATION OF THE UNIT
At high ambient temperatures the refrigeration unit will only
perform adequately when properly ventilated.
The refrigeration unit is ventilated via two openings
in the
wall of the caravan (see fig. 5). Fresh air enters through the
lower opening and warm air is discharged through the upper
one.
Locate the lower opening immediately above the floor of the
recess, and the upper one as high
as possible above the
condenser (C) of the refrigeration unit, at least as shown
in
fig. 6b but preferably as shown in fig. 6a.
Ventilation grilles Fig. 2
The openings in the caravan wall must be fitted with the
Electrolux ventilation systems.
Fitting the grilles, model A 1620, which were specially
developed by Electrolux for this purpose (shown as D
in fig.
6). It
is a good idea, to install the frame R 1640 (A in the
same figure),
at the same time. Then the grilles can be
easily removed which permits inspection and small repairs
to be carried out without the necessity for removing the
refrigerator from the recess.
If there is no outer grille at floor level where leaking gas can
escape, a 40 mm hole to the outside should
be made in the
floor of the recess to drain any unburnt gas to the outside
gas.
Fit the hole with wire mesh and
an angled plate to protect
from stones, mud etc.
Removal of flue gases
The ventilation passage at the rear of the recess, between
the outer wall of the vehicle and the refrigerator (fig.
6) , is
sealed off against the living space, and so cold draughts are
excluded (winter camping) and no flue gases can penetrate
into the vehicle. Thus a special flue outlet is no longer
necessary -the gases are dispersed through the upper vent
grille.
Note: With this mode of installation the same type of grilles
(without
an integrated flue outlet), should be installed at the
upper as well as at the lower vent open-ning. The angled
T-piece for the flue tube (when delivered) should not
be
used in this case.
The top of the enclosure above the flue tube (I), fig
6,
should be covered with aluminum sheet metal, as indicated
in (B), to facilitate the heat dispersion.

CAUTION! CHECK THAT THE GAS SUPPLIED TO
THE REFRIGERATOR IS AT THE CORRECT
PRESSURE. SEE THE REDUCING VALVE ON THE

.,
-=-
Check that this is stated on the data plate. The refrigerator
is not designed for operation on town gas or natural gas.
The gas installation should only be carried out
by an
authorized
gas fitter.
T
he supply pipe should preferably be of copper. If any other
material is used, it
must be of a type approved for use with
continuously operating bottled-
gas appliances, and have
th readed compression connections th roughout. PUSH-ON
CONNECTIONS
MUST NOT BE USED (We do not appro-
ve the use of rubber" type flexible tubing for connecting
permanently operating appliances of this type in the United
Kingdom). All connectors etc. should be of a type specifical-
ly designed for the type and
diameter of the connection pipe
used, and screwed joints should be sealed with a joining
compound approved for use with bottled gas.
The gas supply pipe should be connected to the gas inlet
p
ip e on the right hand side of the gas control valve by
means of a suitable
th readed compression coupling.
In making the connection to the refrigerator, a gas cock of
an approved type for use on LPG must be incorporated
in
the supply line in a position which is readily accessible to
the user. For eventual servicing purposes, the union should
be on the outlet side of the cock and the pipework should
be positioned so as not to prevent the refr
ig erator from
being readily withdrawn.
ELECTRICAL CONNECTI ON
The electrical installation must be carried out in a proper
and durable manner, taking into account all relevant regula-
tions and codes of practice. For mains voltage operation, it
is important that the circuit to and in the caravan is effec-
tively earthed. ALL
MAINS VOL T AGE WIRING IN THE
CARA-VAN MUST BE INSTALLED IN ACCORDANCE
WITH CURRENT REGULATIONS INCLUDING THE
USE OF AN OUTLET AND COUPLER TO BS 4343/-
CEE17.
For connection to a 230 V electricity supply, the refrigerator
has a 3-core mains lead which is intended for connection to
a properly earthed plug and socket outlet or fused spur.
IMPORTANT: The wires
in the mains lead of this appliance
are coloured in accordance with the following code:
GREEN-AND-YELLOW = EARTH
BLUE = NEUTRAL
BROWN = LIVE
As the colours of the wires
may not correspond wi th the
coloured markings identifying the terminals
in your plug, in
the United Kingdom, proceed as follow s:
The wire which is coloured GREEN-AND-YELLOW must be
connected to the terminal
in the plug which is marked with
the letter E or by the earth symbol or coloured green
or
green-and-yellow.
The wire which is coloured
BLUE must be connected to the
terminal which is marked with the letter N
or coloured black.
The wire which
is coloured BROWN must be connected to
the terminal which is marked with the letter L or coloured
red.
3 amp. fuse.
In other countries, the fuse rating will depend
upon the voltage and local practice.
230 V S upp lies.
Check that the voltage stated on the data plate is the same
as the mains voltage in use (230 V).
Electrical lea ds must be routed and secured so that
t hey cannot come into con t act wi th hot or sharp par ts
of
the re fri ge r ato r.
12 V Supplies
Connect the refrigerator to the vehicle battery by a direct
cable. To avoid a voltage drop, the cross sectional area of
the connecting
cab le between battery and refrigerat or must
be at least 2.5 mm2 if the distance is less than 9 meter s,
and at least 4 mm2 if the distance is more than 9 meters
To ensure satisfactory operation, the positive lead must be
fitted with a fuse rated at max. 16 A.
To prevent the refrigerator from draining the battery,
make
sure that the current supplied to the caravan is cut off when
the vehicle engine is not running, for example by fitting an
ignition control relay.

fed via two wires (1) and (2) at terminal block (L).
It
is advisable to feed the reigniter and the lighting from a
separate 12 V source. To do this: remove the wires (1) and
(2) and connect the supply
as is shown in fig. 11 .
In some executions there in an extra terminal block (J), of
fig. 12. In this case one disconnects the wires as said above
but connects the separate supply to (J).
The reigniter should not be connected directly
to a battery
charger but only
over a battery.
WARNING! THIS
APPLIANCE MUST BE EARTHED!
In the United Kingdom, the plug or circuit to the refrigerator
must be fitted with a fuse not greater than 5 amps. If a 13
amp.(B.S.1363) fused plug
is used, it should be fitted with a
12
