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 o 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 sti
brush.
Do NOT hose the compressor compartment with water as this can cause short circuits and
damage on the electrical parts.

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.

rating label which is placed inside the cabinet in the top right hand side.
