allow the heat from the compressor motor to
dissipate. Underneath the appliance these
should be a gap of 15 mm approx. (1/2”). On
a soft surface, e.g. carpet, it may be necessary
to ensure the correct distance by means of
spacers.
6. Electrical supply
The electrical supply should always be in
accordance with the rating plate on the back
of the freezer.
The supply must always be in accordance
with the law and regulations regarding
electrical safety.
If any doubts, contact your supplier.

7. Starting Up
In case the compressor does not start when
the freezer has been plugged in, the electrical
supply may not be in order. Check if there is
an electricity supply to the plug or if the fuse
is blown. If not please go to trouble shooting
page 5.
8. Operating the freezer
The empty freezer should be switched on for
at least 5-6 hours prior to loading of the
freezer.
The freezer should not be loaded above the
inside walls which is also the load line limit.
Please note: After the lid has been opened,
there will be a vacuum created inside the
freezer due to the low temperatures. Wait a
few minutes before trying to re-open the lid
otherwise the handle could be damaged.
9. Defrosting
In order for the freezer to work to its
maximum efficiency the cabinet should be
defrosted when a approx. 2mm thick ice layer
has formed inside the cabinet.
The ice layer is easily removed with a plastic
or wooden scraper.
Never use a sharp metal object which
might will cause damage to the inner liner.
The defrosting frequency is determined
mainly by two factors the usage pattern
(number of lid openings) and the relative
humidity.
Excess water can be drained out by using the
drain water outlet on the front of the freezer.
10. Cleaning
Cleaning should be done when needed.
When used in a dirty environment it might be
necessary to remove the compressor
