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.
The wires in this mains lead are coloured in accordance with the following code:
Green/Yellow: Earth, Blue: Neutral, Brown: Live.
The main electrical connections must be done by skilled electricians.
Start-up of the cabinet
Before use, we recommend that the cabinet is cleaned, see the section on maintenance and cleaning.
Important !
If the cabinet has been vertically placed during transport, please wait 2 hours before starting up the
cabinet.
Connect the cabinet to a socket and turn on the switch on the control panel, see fig. 1.9.

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.
