be allowed to escape by briefly turning on the refrigerator
or other appliances. This will ensure that the flame lights
immediately.
If the flame goes out (by gust of wind etc.), the igniter is
immediately activated and reignites the gas.
Note: The control electronics and the igniter must have
12 V DC supply to operate.

FIG. 1
This refrigerator is equipped with an Automatic Energy
Selector (AES) which controls its operation and energy
supply.
The system selects the available energy source in the
order:
230-240 V - 12 V - LP gas
No manual operation is necessary for selecting the
energy source.
The control panel is shown in fig.1.
The refrigerator is set into operation by pushing button
(A) (main switch). The AES LED (C) lights green showing: AES system working. Push- button (B) is used for
setting the electronic thermostat. The thermostat LEDs
(D) shows the chosen temperature position. When there
is a demand for refrigeration, AES will connect the most
favourable of the available energy sources.
Note: 12 V must always be available to supply the
electronics.
STARTING THE REFRIGERATOR
All references are to fig. 1.
LP Gas operation
AES will select LP gas operation under the following
conditions:
• No AC (230-240 V) available
• Engine not running (no high current at 12 V DC
available)
• AC available but too low
• Engine running but DC supply too low
(condition three and four are briefly described in
item Undervoltage operation)
When the system chooses LP Gas operation, the flame
failure device is automatically opened, allowing the gas
to flow to the burner. At the same time, the electronic
igniter is energized.
After initial installation, servicing, or changing gas cylinders etc., the gas pipes may contain some air that should
Gas trouble-shooting
If the AES LED (C) is flashing red, the system was not
able to start or continue gas operation. Set the switch
(A) to "OFF" and check that there is enough gas in the
gas bottle, that its valve is open and that any valves in
the gas line to the refrigerator are open.
Then push button (A) to "ON" again. After 10 sec. AES
will repeat the ignition sequence. When the AES LED
(C) again starts flashing red after 30 sec., the trouble
persists (air in the line, no gas?). Switch (A) briefly off
and then on again. It might be necessary to repeat this
operation 2-3 times if the tubing contains air (after
changing gas bottles, repairs etc.).
If this does not help, you should consult a service
technician.
230-240 V Operation
When a mains connection is available, AES will select
this. Please note, that even being in AC mode, 12 V DC
is necessary for the internal supply of the electronics.
12 V Operation
AES will select the 12 V mode of operation only when
the vehicle engine is running (detected by the alternator
connection of the fridge D+).
SWITCHING BETWEEN ENERGY
SOURCES
When switching from one energy source to another,
there are some delays implemented in the AES system.
The 15 min. delay between switching off the engine and
starting gas mode is intended to delay the starting of gas
mode e.g. when stopping at a filling station.
WARNING: It is not allowed to have a naked
flame at a gas filling station. If you are not sure,
that your stop is shorter than 15 min., you are
advised to switch off the main switch (A), fig. 1,
when stopping at a filling station.
Undervoltage operation
The AES system is designed to guarantee the maximum
cooling efficiency under any circumstances. Therefore,
the system monitors continuously the voltage level while
being in either 12 V DC or 230-240 V AC mode. If the
voltage is too low, the system switches to Gas mode
shown by the yellow LED (E in fig. 1.). The system stays
in Gas mode, until the electrical supply voltage has
recovered to normal level.
REGULATING THE TEMPERATURE
The position number refers to fig.1.
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
13
foodstuffs.
The temperature of the refrigerator main compartment
is set for all three sources of energy, by means of the
thermostat knob (B). After turning on the refrigerator the
system automatically chooses the mid- position. With
some experience you will soon find a suitable setting.
This normally does not need resetting because the
same thermostat controls the main compartment temperature for any of the three sources of energy.
TRAVEL CATCH
The refrigerator is equipped with two travel catches.
Make sure that both are engaged when the motorhome
is on the move.
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 that might give
off flammable gases.
The 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.
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 packages.
ICE MAKING
Fill the ice tray to just below the brim with drinking water
and place it on the freezer shelf.
Ice will be made more rapidly if the thermostat is set at
its highest position, but be sure to move the thermostat
back to normal setting when the ice is formed, the
refrigerator might otherwise become too cold.
DEFROSTING
Frost will gradually accumulate on the refrigerating
surfaces. It must not be allowed to grow too thick as it
acts as an insulator and adversely affects refrigerator
performance. Check the formation of frost regularly
every week and when it gets about 3 mm thick, defrost
the refrigerator.
To defrost the refrigerator, turn it off and remove the ice
trays and the food item, leave the cabinet and freezer
doors open.
Do not try to accelerate defrosting by using any kind of
heating appliance, as this might damage the plastic
surfaces of the refrigerator. Neither should any sharp
objects be used to scrape off the ice.
Defrost water runs from a collector channel to a receptacle at the rear of the refrigerator where it normally
evaporates.
Heavy frosts build up on the freezer plate and the cooling
fins, and a lot of defrost water, move the plastic drain
tube in to a watertight bucket or container. (Access
through the lower ventilation grill on the outside of the
motorhome). As the frost melts, the water will flow into
the container. Replace the drain tube to its original
position after defrosting.
14
Defrost water in the freezer compartment should be
mopped 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
bicarbonate 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 refrigerator as they may damage the surfaces and leave a
strong odour.
The exterior of the refrigerator should be wiped clean
now and then, using a damp cloth and a small quantity
of detergent. But not the door gasket, which should only
be cleaned with soap and water and then thoroughly
dried.
The cooling unit behind the refrigerator should be
cleaned with a brush from time to time, but make sure
that the refrigerator is switched off when doing this.
HEATING CABLE
During the summer months of high temperatures and
humidity, the metal frame between the freezer and fresh
food compartments may have water droplets forming.
This refrigerator comes standard with a 12 V (DC)
heating cable that will evaporate the water droplets when
they form.
To have the heating cable on, you position the switch
located beneath the control panel to I. The heating cable
can be left on continuously or only used when temperatures require it.
Note: The heating cable will draw 12 V (DC) power
continuously when in the ON (I) position. It should be
turned OFF (0) when a charging source is not available.
WINTER OPERATION
Please check that the ventilation grilles are not blocked
by snow, leaves etc.
ELECTROLUX ventilation grilles model L500, can be
fitted with winter covers, model WA130, to protect the
cooling unit against cold air. The covers may be fitted
when the outside temperature is below approx. 10°C 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.
TURNING OFF THE REFRIGERATOR
If the refrigerator is not to be used for some time:
1. Set the switch (A), fig. 1, to "OFF".
2. Shut off any on-board valve in the gas line to the
refrigerator.
3. Empty the refrigerator. Defrost and clean it as described earlier. Leave the doors of the refrigerator
and frozen food compartment ajar.
4. When the motorhome is laid up for a long period of
time (e.g. during the winter months), we suggest
fitting the winter covers WA130 onto the vent grills.
IF THE REFRIGERATOR FAILS TO WORK
SOME USEFUL HINTS
Check the following points before calling a service technician:
Make sure that:
1.
2.
3.
4.
5.
6.
that the green AES LED goes on, when the switch
(A) is set to "ON" (12 V must be available).
when mains are connected but the refrigerator stays
in gas operation: Is the refrigerator correctly connected and is the fuse (230-240 V) intact?.
is the 12 V fuse intact?
Disconnect the wall plug, and the 12 V wires
before servicing. Check the fuses on the circuit
board, (under the black cover at the top of the refrigerator and behind the control panel).
Remove the two screws holding the control panel,
pull out the control panel with its electronics. Remove
the cover and check the fuses.
if the refrigerator does not operate in DC mode when
the engine is running:
Is the alternator (D+) connection made correctly?
if the AES LED (C) flashes red: see chapter Gas
trouble-shooting.
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.).
2. The evaporator is frosted up.
3. The temperature control setting is incorrect.
4. The gas pressure is incorrect - check the pressure
regulator at the gas container.
5. The ambient temperature is too high.
6. Too much food is loaded at one time.
7. The door is not properly closed or the magnetic
sealing strip is defective.
If the refrigerator still does not work properly, call a
service technician.
WARNING! The sealed cooling system must not
be opened, since it contains corroding chemicals under high pressure.

INSTALLATION/BUILDING-IN
The refrigerator is intended for installation in a motorhome, and the description relates to this application.
The refrigerator must not be exposed to radiated heat
from hot objects.
Excessive heat irradiation impairs performance and
leads to increased energy consumption. For this reason
the refrigerator 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 set open. This would reduce the
ventilation airflow to the cooling unit and reduce refrigeration performance.
The enclosure
The refrigerator must be installed in a substantial
enclosure and must be level, the dimensions 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 weight of the
refrigerator.
Battens must be installed at the bottom, sides and top
of the enclosure and fitted with sealing strips.
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
Six fasteners are fitted in plastic bushings in the side
walls of the refrigerator, fig. 2. They are used for securing
the refrigerator 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 securely, also considering the
forces due to the movement of the vehicle.
With the refrigerator in place, drive the screws through
the lining of the refrigerator into the walls of the enclosure.
There must not be more than 3 mm of clearance between refrigerator and enclosure on each side. If necessary, 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.

FIG. 2
VENTILATION OF THE UNIT
At high ambient temperatures the refrigeration unit will
only perform adequately when properly ventilated.
Side ventilation.
The refrigerator unit is ventilated via two openings in the
wall of the motorhome (fig. 3a).
Fresh air enters through the lower opening and warm air
is discharged through the upper one.
The lower opening should be located at floor level (to
allow any leaking gas to escape to the outside).
The upper ventilation opening should be located above
the condenser, as high as possible, to ensure good
ventilation.
Roof ventilation
The ventilation of the cooling unit can also be done via
one opening in the wall of the motorhome and one on
the roof for the roof vent (fig. 3 b).
Fresh air enters through the lower opening and warm air
is discharged through the roof vent.
Ventilation grilles
We recommend fitting 2 side vents, model L500,
alternative one L500 and one roof vent model R500,
which are specially developed by Electrolux for this
purpose.
The L500-ventilation grilles permit inspection and small
repairs to be carried out without the necessity to remove
the refrigerator from the recess.

Removal of flue gases
The ventilation passage at the rear of the recess, between the outer wall of the motorhome and the refrigerator (fig. 3a/b/c), must be sealed off against the living
space, so cold draughts are excluded (winter camping)
and no flue gases can penetrate into the motorhome.
The flue gases are dispersed through the upper vent
grille or the roof vent together with the ventilation air.
The top, bottom and sides of the ventilation passage
should be insulated to prevent condensation and cold
draughts.

The refrigerator is designed for operation on LP gas, the
pressure of which must be 28 mbar for Butane and 37 mbar
for Propane. Check that this is stated on the data plate.
The refrigerator is not designed for operation on
town gas or natural gas.

CAUTION! CHECK THAT THE GAS SUPPLIED
TO THE REFRIGERATOR IS AT THE CORRECT
PRESSURE. SEE THE REDUCING VALVE ON
THE LP GAS CONTAINER.
the wire which is coloured Brown must be connected
to the terminal which is marked with the letter L or
coloured Red.
WARNING- THIS APPLIANCE MUST BE EARTHED
IMPORTANT
The gas installation should only be carried out by a
person experienced in gas fitting. It is recommended that
the gas pipe feeding the refrigerator is so arranged that
it is possible to turn off the supply of the refrigerator.
It must be of a type approved for use with continuously
operating bottled gas appliances, and have threaded
compression connections throughout. PUSH-ON CONNECTIONS MUST NOT BE USED (We do not recommend 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 specifically 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
pipe (outside diameter 8 mm.) by means of a suitable
gas-tight compression fitting, e.g. olive.
In making the connection to the refrigerator, a union gas
cock of an approved type bottled gas must be incorporated in the supply line in a position that 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 refrigerator from being readily withdrawn.
On completion of installation, the system must be
pressure tested by a qualified technician.
ELECTRICAL CONNECTION
The electrical installation must be carried out in a proper
and durable manner; taking into accounts all relevant
regulations and codes of practice. For mains voltage
operation, it is important that the circuit to and in the
motorhome is effectively earthed.
For connection to a 230-240 V electricity supply, the
refrigerator has a 3-core mains lead which is intended
for connection to a properly earthed plug and socket
outlet. The socket outlet should be fitted in the motorhome
in a position readily accessible to the user, within reach
of the mains lead. In the United Kingdom, the plug and
socket outlet should be of the non-reversible type.
As the colours of the wires in the mains lead of this
appliance may not correspond with the coloured markings identifying the terminals in your plug, proceed as
follows:
-
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 wires in this mains lead are coloured in accordance
with the following code:
-
green/yellow:
earth
blue:
neutral
brown:
live
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 3 amp. fuse, ASTA approved to B.S. 1362.
In other countries, the fuse rating will depend upon the
voltage and local practice.
230-240 V Supplies.
Check that the voltage stated on the data plate is the
same as the main voltage in use (230-240 V).
Plug the 230-240 V refrigerator power cord into an easily
accessible wall socket.
Electrical leads must be routed and secured so
that they cannot come into contact with hot or
sharp parts of the refrigerator.
12 V and "D+" Connection
The 12 V connection of the refrigerator is shown in
fig. 4. The (+12 V) and (-) pole have to be connected
directly to the "house battery". Do not use the chassis
for the return lead.
12 V supply must not be connected to a voltage controller or similar device as the AES itself monitors the DC
voltage.
+12 V should be permanent attached, and must not be
cut out when the ignition key is turned off.
All connections should be screwed or soldered to keep
voltage drop to a minimum. The positive conductor must
be protected by a 20 A fuse.
The connection D+ (alternator) has to be connected
to the corresponding outlet of the vehicles electrical
system.
FIG. 4
18
D
12V DC
Cross-sections
TECHNICAL DATA
The D+ (alternator) is a signal cable and therefore 1-1.5
mm2 is sufficient.
Connection to 12 V + and - must be done with a 10 mm2
wire if the total wire length (+ and - wire together) is
maximally 12 m.
If longer wires are required a bigger cross-section cable
is needed.
Please consult a specialist, if you are not familiar with the 12 V electrical system in your motor
home.
Interior light - bulb - change
If the bulb has to be replaced, proceed as follows:
1. Remove the cover from the lamp body by pushing it
backwards.
2. Remove the bulb.
3. Put in a new bulb (12 V, max. 5 W).
Spare part number for bulb: 200 72 90-03.
4. Push the lamp cover back in place.
