DEFROSTING
W ARNING:
Normally
the temperature of items would rise during defrosting and so, they
should be consumed within 24 hours or discarded.
Do not try to accelerate defrosting by using any kind of heating appliance, as this
might damage the internal surfaces of the freezer.
No sharp object be used to scrape off the ice as this may damage the internal
surfaces of the freezer.
Frost will gradually accumulate on the freezer surface. It must not be allowed
to grow thick as it acts as an insulator and adversely affects freezer
performance.
Check the formation of frost regularly and when it gets around 5mm thick,
defrost the appliance.
To defrost the appliance, turn it off and remove all food items.
Once defrosting is complete, clean the interior thoroughly.
IM PORT ANT:
Before using the freezer again, ensure that no foreign bodies are present in the flue
chimney, or the burner (dust, insect, nests, waste paper etc.)
WARNING:
The needle valve screw used for admitting the ammonia / hydrogen filling charge to
an absorption unit is fitted to the unit’s reservoir. It is a strictly applied provision of
the guarantee extended on the unit to the customer, that any interference with the
filling valve screw will automatically void the guarantee. The absorption unit must
not be opened, since it contains corroding chemicals under high pressure.
