1. The appliance
1.1.Specifications
The appliance is a 60-litre upright refrigerator, operating with a wet absorption cooling
system.
At ambient temperatures between +16°C and +32°C, the cooling compartment
temperature can be adjusted between 0°C and +6°C using the thermostat. The
minimum temperature of the freezer compartment is - 12°C.
You can make ice cubes using the ice tray placed in the freezer compartment.
Defrosting of the appliance is either automatic, where the appliance is switched off for
1,5 to 2 hours every 24 hour by the installed control, or it is semi-automatic and can
be initiated by pressing the defrost switch. Restart is done automatically in both
cases.

groove of casing. Screws securing the wires must stand outwards from
lighting device. (Fig. 40)

shield. (Fig. 48)
The light shield can be slid in place by slightly pressing the blocking tab
with a screwdriver.

control is different from those with electromechanical control!
- The boiler-insulation can be reinserted by turning it in. The rims must be
snapped together by slightly pressing the metal casing.
- Turn in boiler-insulation so that the securing bore is in the correct position.
- Attach boiler-insulation to back panel with securing screw.
- Adjust wires.
- Connect electrical connections at the appropriate points.

From the back panel side, insert a 4x100 standard screwdriver through
the lead bore. Slightly push the flat connector of sensor insulation
socket onto the edge of the screwdriver, secure with insulating tape.
Fold back the end of wire with insulation socket by 180°. Using the
screwdriver, pull the wire through the bore, then using that pull through
the other end of the wire as well. (Fig 73, 74)
When pulling through, pay attention to the position of the lead rubber
gasket. If it falls out, it must be put back in the bore by all means.
- Place the sensor head in the nest of the sensor cover, screw the cover
back in place.
- Place the 2 plugs back in the bores of cover.
