Safe Servicing Practices For All Appliances
Avoid personal injury and/or property damage by observing important Safe Servicing Practices.
Following are some limited examples of safe practices:
1. DO NOT attempt a product repair if you have any doubts as to your ability to complete the repair in a safe and
satisfactory manner.
2. Always use the correct Replacement Parts as indicated in the parts documentation. Substitutions may defeat
compliance with Safety Standards Set For Home Appliances. Do not exceed maximum recommended wattage on
light bulb replacements. Doing so could blow fuses and/or damage transformers.
3. Before servicing or moving an appliance:
• Remove power cord from the electrical outlet, trip circuit breaker to the OFF position, or remove fuse.
• Turn off water supply if applicable.
• Turn off gas supply if applicable.
4. Never interfere with the proper operation of any safety device.
5. Use ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE. Substitutions may defeat
compliance with Safety Standards Set For Home Appliances.
6. GROUNDING: The standard color coding for safety ground wires is GREEN, or GREEN with YELLOW STRIPES.
Ground leads are not to be used as current carrying conductors. It is EXTREMELY important that
the service technician reestablish all safety grounds prior to completion of service. Failure to do so will create
a hazard.
7. Prior to returning the product to service, ensure that:
• All electrical connections are correct and secure.
• All electrical leads are properly dressed and secured away from sharp edges, high-temperature components,
and moving parts.
• All non-insulated electrical terminals, connectors, heaters, etc. are adequately spaced away from all metal
parts and panels.
• All safety grounds (both internal and external) are correctly and securely connected.
• All panels are properly and securely reassembled.

Maintenance
It is recommended that you keep the wine cellar as
clean as possible. Unplug the wine cellar before
cleaning.
Do not use any abrasive or strong scented substances.
Use a smooth cloth or sponge and light detergent.
It is very important to check regularly that the air
circulation underneath and behind the cellar is not
blocked. Condensation collects in a small cup at the
back of the cellar. The cup has a sponge which helps
the condensation to evaporate. Check that the plastic
pipe routing the water from the inside to the cup is not
blocked by dust or dirt.
If the wine cellar fails to work, check the following
before proceeding with troubleshooting the unit:
• Is the power supply fuse intact ?
• Is the electric power plug properly inserted in its
receptacle ?
• Is the wine cellar switched on ?
The wine cellar is equipped with overheating protection.
Check whether this has been triggered or not.
How To Store Different Types Of
Bottles
Bottles should be stored in your wine cellar according
to their size. The most well known types of bottles are
the “Bordeaux” and the “Burgundy”. These bottles are
not all identical. The most widely recognized bottles
are the “Tradition” and the “Légère”. The “Champenoise”
and the “flûte d’Alsace” bottles have different diameters
and heights. Take these differences into account when
storing your wine and avoid mixing the bottles.
It is important to store bottles on their side in order for
the cork to remain in contact with the wine. Place
bottles top to bottom in the cellar for optimum volume
use. The illustrations show the best way to stack the
“Burgundy” and the “Bordeaux Tradition”.

Introduction
In 1922, the Swedish engineers Baltzar v. Platen and Carl Munters developed a continuously working absorption
cooling unit which is not subject to mechanical wear and tear (unit has no moving parts), and which uses an auxiliary
gas (hydrogen) as its pressure equalizing gas. Until the present day, absorber aggregates have been utilizing this
principle. An absorption unit consists of steel pipes which are welded together to form a complex pipe system which
generates the different thermodynamic conditions required for the absorption process. The success of these
refrigerators results from their silent operation, long life span (no moving parts), and the different methods for
powering them (main operation: 120-230V, battery operation: 12V, operation by gas, oil and alternative energy
sources). This feature makes these refrigerators ideally suited for use in hotels or leisure vehicles.

Description of Function
1. Boiler:
The strong ammonia solution is heated, which sends
ammonia gas to the condenser. The weak ammonia
solution returns through the liquid heat exchanger to
the absorber.
2. Condenser:
The ammonia gas is condensed to liquid by heat
dissipation.
3. Evaporator:
The liquid ammonia flows into the evaporator. The
evaporation of ammonia in the hydrogen atmosphere
absorbs heat. The heavier ammonia/hydrogen
mixture flows down to the absorber vessel.
4. Absorber:
The rising ammonia gas is absorbed by the weak
solution which flows down to the absorber vessel.
Hydrogen is separated from ammonia and then rises
to the evaporator.
Important
1. The cooling unit needs ventilation.
2. The cooling performance depends on air circulation.
3. The condenser component is affected by heat. Heat
accumulation leads to performance loss.
4. Correct installation of the Electrolux ventilation grilles
ensures best possible performance.
Features of the optimum installation:
1. Ventilation grilles with a free cross-section= 250cm2.
2. Upper ventilation grille positioned above the
condenser.
3. Distance between cooling unit and wall must be
approximately 3/4” to 1” (20-25mm).
4. Heat deflector to the upper grille, to guide heated air
out.
Depending on the model, the cooling unit function is more
or less dependent on position. When checking function,
the cooling unit should be level front to back and side to
side.
Description of Function
Electric Thermostat:
Senses with the capillary tube temperature, and switches
power to the heater on and off.
Gas Thermostat:
Senses with the capillary tube temperature, and opens or
closes the main gas supply (bypass remains open
constantly because of pilot flame).
Thermocouple:
When the thermocouple tip is heated by the gas flame,
electricity is generated. This feeds the safety valve
solenoid which keeps the valve open as long as the flame
burns.
Gas Control Valve:
In conjunction with the gas thermostat, this gas control
devise allows either an open or closed position. A Zero,
Min, Mid and Max Position valve is used in products not
having gas thermostats. Both types have a built in safety
device. By pressing the safety valve button, the gas
flow to the burner is opened. When the flame is lit, the
thermocouple powers the valve solenoid and the valve
remains open. If the flame is extinguished, the valve
closes.
Gas Filter:
It is positioned in the gas supply pipe and may obstruct
the gas flow if it is dirty or damp. This obstruction can
result in poor cooling or no cooling in gas mode.
Piezo Ignition:
Pressure produces high voltage in the piezoelectric
crystal. The high voltage gives via ignition cable and an
electrode, a spark in the burner where the gas is lit.
Burner:
Consists of burner housing, mixing chamber and burner
jet. The burner jets are marked with numbers. Only jets
with the correct number for the model in question must
be used.

Re-ignitor:
An electric re-ignitor powered by a supply voltage of approximately 12V, generates via an ignition cable and an
electrode, a spark in the burner where the gas is lit.
The re-ignitor automatically repeats this operation until a “feedback” signal to the electronics registers the presence
of a flame. On the re-ignitor, there is a voltage supply connection which is powered by the re-ignitor switch. There is
also a connection for the switch control light.
Flue Baffle:
This distributes the heat in the boiler area during the gas operation (not required for all models). A performance loss
occurs if this baffle is missing. The length of baffle will vary depending on model.
Burner Jet:
Burner jets are designed for the specific gas operating pressure (28 to 50 mbar). Only the burner jets specified for the
model and gas pressure stated on the data plate, must be used.
