OPERATING AND INSTALLATION INSTRUCTIONS FOR ELECTROLUX REFRIGERATORS
INTRODUCTION
We are pleased that you have chosen this refrigerator and hope you will derive much satisfaction from using it, but first a few well-meant words of advice:
It is important to read through these instructions carefully before using the refrigerator.
To ensure good refrigeration and economical operation, the refrigerator must be installed and used as described in these instructions.
The refrigerator is designed for building-in to leisure vehicles such as caravans or motorhomes.
The appliance is certified according to the EU-Gas-Directive 90/396/EEC.
This refrigerator comes with an
Automatic Energy Selector
which controls operation and energy supply. To put the refrigerator in operation, just trip the main switch - AES manages the rest.
TRANSIT DAMAGE
Inspect the refrigerator for damage. Transit damage must be reported to whoever is responsible for delivery not later than seven days after the refrigerator was delivered.

OPERATING INSTRUCTIONS
CONTROLS
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. 3.
The refrigerator is set into operation by pushing button (A) (main switch). The AES LED (C) lights green showing: AES system working. Pushbutton (B) is used for setting the electronic thermostat. The thermostat LEDs (D) show the choosen 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. 3.
LP Gas operation
AES will select LP gas operation under the following conditions:
●No AC (230 V) available
●Engine not running (no high current at 12 VDC 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 which should 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 a DC (battery) supply to operate.
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 0 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 3-4 times if the tubing contains air (after changing gas bottles, repairs etc). If this does not help, you should consult a service technician.
230 V Operation
When a mains connection is available, AES will select this. Please note, that even being in AC mode, 12 V DC is neccessary 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).
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 to delay the starting of gas mode e.g. when stopping at a filling station.
Nevertheless 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. 3, 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 monitores continously the voltage level while being in either 12 V DC or 230 V AC mode. If the voltage is too low, the system switches to Gas mode shown by the yellow LED (E in fig.3). The system stays in Gas mode, until the electrial supply voltage has recovered to the normal level.
WINTER OPERATION
Please check that 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. 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.
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.
The temperature of the refrigerator main compartment is set
8
for all three sources of energy, by means of the thermostat knob (B). After turning on the refrigeratior the system automatically chooses the midposition. 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
Make sure that the travel catch is engaged when the caravan 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 refrigerator is less demanded and the cooling unit has more reserves. 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 contact 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 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 `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 surfaces 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
receptacle at the rear of the refrigerator where it evaporates. 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 again, 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 re-frigerator is switched off when doing this.
TURNING OFF THE REFRIGERATOR
If the refrigerator is not to be used for some time:
1.Set the switch (A), fig. 3, 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 the frozen food compartment ajar. Use the travel catch to hold in this position.
4.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 THE `FRIDGE FAILS TO WORK
Check the following points before calling a service - technician:
1.that the green AES LED goes on, when the switch (A) is set to "ON" (12 V must be available).
2.when mains are connected but the fridge stays in gas oeration: Is the refrigerator correctly connected and is the fuse intact?
3.in transit, if the fridge does not operate in DC mode: Is the alternator (D+) connection made correctly ?
4.if the AES LED 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.
