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= 250cm
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.
