Important safety instructions
1. To obtain full use of the cabinet, we recommend reading this instruction manual.
2. It is the user’s responsibility to operate the appliance in accordance with the instructions
given.
3. Contact your dealer immediately in case of any malfunctions.
4. Place the cabinet in a dry and ventilated place.

Electrical connecting
The cabinet operates on 230 V/50 Hz.
The wall socket should be easily accessible.
All earthing requirements stipulated by the local electricity authorities must be observed. The
cabinet plug and wall socket should then give correct earthing. If in doubt, contact your local
supplier or authorized electrician.
The flexible cord fitted to this appliance has three cores for use with a 3-pin 13-Amp or 3-pin 15-
Amp plug. If a B.S. 1363 (13-Amp) fused plug is used, it should be fitted with a 13-Amp fuse.

normal reading
Set new temperature:
Press this key and the display shows the set temperature.
Press this key to increase the set temperature.
Press this key to lower the set temperature.
Press this key to save the new settings. The display will flash with the new value and will
then return to normal reading.
Changing of parameters:

PF1 Flashing in the display: indicates that the cabinet sensor is defective.
The cabinet will strive to keep the set temperature until it has been repaired.
Defrosting
The cabinet defrosts automatically with pre-set intervals. If the door to the cabinet is opened or the
contents of the cabinet is changed frequently it may become necessary to defrost the cabinet
manually.
Pressing this key continuously for more than 3 seconds will start a manual defrosting and
then return to normal operation.
Defrosted water runs to a container placed in the compressor compartment and evaporates.

Maintenance and cleaning
Switch the cooler off at the socket.
The cabinet must be periodically cleaned. Clean the external and internal surfaces of the cabinet
with a light soap solution and subsequently wipe dry. External surfaces can be maintained using
steel oil.
Do NOT use cleansers containing chlorine or other harsh cleansers, as these can damage the
stainless steel surfaces and the internal cooling system.
Clean the condenser and the compressor compartment using a vacuum cleaner and a stiff brush.
Do NOT hose the compressor compartment with water as this can cause short circuits and damage
on the electrical parts.
Service
The cooling system is a hermetically sealed system and does not require supervision, only cleaning.
If the cabinet fails to cool, check if the reason is a power cut.
If you cannot locate the reason to the failure of the cabinet, please contact your supplier. Please
inform model and serial number of the cabinet. You can find this information on the rating label
which is placed inside the cabinet in the top right hand side.
Disposal
Disposal of the cabinet must take place in an environmentally correct way. Please note existing
regulation on disposal. There may be special requirements and conditions which must be observed.
