1 SAFETY
1.1 Safety instructions
Danger!
Repairs may be carried out only by customer service engineer,
trained by the manufacturer.
Improper repairs may lead to danger and damage for the user.
The housing or frame may be live in case of error.
Do not touch components in the appliance; even the modules can
be live.
Before commencing repairs, always disconnect the appliance from
the power supply.
If tests under tension are required, always use a residual-current-
operated circuit-breaker!
The protective conductor connection must not exceed the
standardised values. This is essential for personal safety and
appliance function.
When repairs are complete, conduct a test in accordance with VDE
0701 or the corresponding national regulations as well as a
performance test.
Conduct a leak and performance test on the refrigeration circuit.
1.2 Repair instructions
Caution!
Comply with ESD information.
Never attempt repairs by randomly replacing components.
Always proceed systematically and comply with the technical
documentation for the appliance.
As a rule, printed-circuit boards are not repaired but are completely
replaced by original spare parts. Exceptions are documented
separately.
When handling refrigerants, wear goggles and protective gloves. If
refrigerant splashes into eyes, rinse with plenty of water. EU and
CN models are using R600a, US models are using R134a.
Do not solder pipe connections in refrigeration. Use Lokring
connections.

There are two different icemakers for SbS refrigerators:
- Flurida ice maker for IWD appliances
- EMZ ice maker for IWS appliances
The main difference between these icemaker concern the water inlet
and the dispenser system. The specific differences are described in
the following chapter.

3 FUNCTIONS
3.1 Cooling system
The appliance and has two separate cooling circuits, one for the
freezer compartment (FC) and one for the refrigerator compartment
(RC). Two evaporators (①FC/ ②RC) share one compressor (④)
and a solenoid valve(③) regulates the refrigerant supply. When both
compartments need refrigerant, the FC has priority over the RC.
If the appliance is equipped with an inverter compressor, the
refrigerant goes through the condenser first then the FC heating tube.
If the appliance is equipped with a normal compressor, the refrigerant
goes through the FC heating tube then the condenser.
3.2 Water circuit
When water is requested by either the water dispenser (③) or the ice
maker (①)it first runs from the water inlet (⑤) through water tubes to
the water filter (②), located in the RC, and then is directed to a water
valve system. The water valve (④) distributes the water.
NOTE: The water tubes, which are connected to the Dispenser
and Ice maker are ¼” big. All other tubes are 5/16” big.

3.2.1 Water flow for Dispenser
From the water valve (④), the water flows into a water tank with a 1-
liter capacity (⑥). The water is dispensed through the Dispenser (③).
NOTE: The freshness of the water may be reduced, if no water
has been dispensed for a longer time.
3.2.2 Water flow for Ice maker
From the water valve (④), the water goes through water tubes in the
rear of the freezer and is then led to the ice maker water inlet. From
there it flows into the ice tray of the ice maker (①).
3.3 Electronic control
This appliance is equipped with 5 NTC sensors, which control the
temperature of FC, RC, TCD, FC-evaporator and RC-evaporator
respectively.
3.3.1 FC/RC Running and temperature control
FC temperature range: -16 °C to -26 °C / 7 °F to -15 °F
RC temperature range: 2°C to 8°C / 35°C to 46°C
When the temperature of FC or RC rises, the control module connects
the solenoid valve (opens to FC evaporator or RC evaporator), FC-fan
or RC-fan, compressor, the FC or RC is under cooling. Once the
selected temperature is reached, the control module disconnects the
fan and also closes the solenoid valve.
RC/ FC
ON: T ≥Tsetpoint + Toffset (2K) + Thysteresis (2.5 K)
OFF: T≤Tsetpoint + Toffset (2K) + Thysteresis (2.5 K)
NOTE: When the relevant compartment door is open, the
compressor is still functioning but the relevant fan stops.

3.3.2 TCD airflow and temperature control
The fan of the TCD sucks in the cold air of the evaporator via the TCD
flap (①). The air is blown into the TCD (②)and then exits the TCD
again through the air outlet flap (③). The fan and the flaps are
controlled by the control module. Once the selected temperature is
reached, the fan stays off and the flaps are closed, but heater runs
intermittently.
The TCD can only be set at either 0°C, 2°C or 4°C / 32°F, 35.5°F or
39°Fvia the display panel.
3.4 Alarm function
If an alarm is triggered, an audible warning signal sounds and an
information window is displayed.
►Tap OK to switch off the audible warning signal.
An alarm may be triggered in the following cases:
Door alarm
The door alarm is triggered, when one of the appliance doors remains
open for longer than 30s. The alarm stops when the door is closed
again.
Temperature alarm
The temperature alarm is triggered, when a compartment becomes
too warm and the food is endangered.
The information window displays the too warm compartment.
Without endangering the frozen food, the temperature alarm is
triggered in this cases:
First use of the appliance.
Putting large quantities of food in the freezer compartment
