1 SAFETY
1.1 Safety instructions
Danger!
►Repairs may be carried out only by customer service
engineers trained by the manufacturer!
►The user may be put at considerable risk and injured by
improper repairs!
►If the appliance is faulty, the housing or frame may be live!
►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 have to be conducted while the appliance is live,
ALWAYS use a residual-current-operated circuit-breaker!
►The protective conductor connection must not exceed the
standardised values! This is essential if no persons are to be
injured and the appliance is to operate correctly!
►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 com-
pletely replaced with 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.
►Pipe connections in refrigeration circuits must not be soldered.
Lokring connections must be used.

4 COMPONENTS
4.1 Control module
The control module is situated on the appliance.
The “Time shortening switch” reduces the run times.
e.g. compressor start-up lockout, fan switch-on delay, etc.
Briefly pressing the switch once reduces the time by 1 min.
Continuously pressing the switch reduces the time every two seconds
by 1 min. Maximum reduction time is 30 min.
4.2 Freezer compartment fan
Fan operation:
►The freezer compartment fan always runs whenever the
compressor is running.
Exceptions:
►The freezer compartment fan starts with a switch-on delay of
60 s after the compressor starts.
►The freezer compartment fan does not run if one of the two
doors is open.
175_58300000116046_ara_en_h.doc – 12.01.12 Seite 5 von 25

5 FUNCTIONS
5.1 Cooling system
The appliance features a single-circuit cooling system utilising
No-Frost technology with circulating air. The evaporator is situated
in the freezer compartment.
The refrigerator compartment fan supplies the refrigerator
compartment with cold air from the freezer compartment. The
refrigerator compartment fan runs whenever the refrigerator
compartment sensor requires refrigeration.
The air returns to the evaporator via an air conductor behind the
drawers.
175_58300000116046_ara_en_h.doc – 12.01.12 Seite 6 von 25

5.2 Defrosting
The defrosting phase is actuated if:
The compressor running time is > than 2 h and the appliance running
time is > 60 h.
The compressor running time is > than 24 h
The compressor running time is > than 6 h and the relative
On duration is > 85 %.
A fault is indicated on the display.
The total door opening time is > 2 min.
Defrosting process
Delay:
is activated if the evaporator sensor is ≤–27 °C.
►The delay is 50 min.
►The freezer compartment fan is on continuously.
►The refrigerator compartment fan is in normal mode.
►The evaporator heater is off.
Defrosting process:
►The maximum defrosting time is 80 min.
►Defrosting ends when the evaporator sensor reaches 13 °C.
►The two fans are off.
►The defrosting heater is on.
Pause:
After the defrosting process, the two fans and the defrosting heater
switch off for 7 min. The two fans start running after a 5 min. switch-on
delay.
5.3 Door alarm
The door alarm is activated if the refrigerator compartment door or
freezer compartment door is open for longer than 1 min. The door
alarm sounds again every minute.
The door alarm is deactivated:
►automatically after 5 min.
►when the door or doors are closed again.

6 REPAIR
6.1 Opening the refrigeration circuit
Whenever the refrigeration circuit is opened, always
replace the dryer before evacuating and filling the
refrigeration circuit.
6.2 Leaks on intake side
If the refrigeration circuit leaks on the intake side,
resulting in repairs, always replace the compressor and
dryer.
If atmospheric humidity penetrates the refrigeration
circuit, the oil in the compressor will be irreversibly
contaminated.

6.5 Changing the heater
6.5.1 Evaporator heater
The air conductor in the freezer compartment must be removed before
the evaporator heater can be changed. The heater can be changed
separately.
Power = 192 watts
Resistance = 252 Ω
6.5.2 Attaching an additional thermal link
As a spare part the evaporator heater has a separate thermal link.
This thermal link is attached in the upper, right area of the evaporator.
175_58300000116046_ara_en_h.doc – 12.01.12 Seite 12 von 25

6.5.3 Air-conductor heater
The heater on the air conductor in the freezer compartment prevents
condensation. The heater runs parallel with the compressor.
The heater cannot be changed separately, the complete rear panel
must be replaced.
Power = 7 watts
Resistance = 6.8 kΩ
175_58300000116046_ara_en_h.doc – 12.01.12 Seite 13 von 25

6.6 Changing the thermal link
The thermal link is attached to the evaporator.
The thermal link can be changed separately.
The thermal link is a fusible cut-out and must be replaced when it has
tripped.
The switch-off value = 77 °C
Thermal links were temporarily delivered with a shorter connection
cable. In this case the thermal link is attached in the upper, left area of
the evaporator.
