Maint Maint enance and Cleaning enance and Cleaning
Before any maintenance or cleaning is
carried out you must DISCONNECT the
appliance from the electricity supply.
Internal Cleaning
Clean the inside and accessories with warm water and
bicarbonate of soda (5 ml to 0.5 litre of water).
Rinse and dry thoroughly.
NEVER use detergents, abrasive powders,
highly perfumed cleaning products or wax
polishes to clean the interior as these will
damage the surface and leave a strong odour.
External Cleaning
Wash the outer cabinet with warm soapy water.
Once or twice a year dust the condenser (black grille)
and the compressor at the back of the appliance with
a brush or vacuum cleaner, as an accumulation of dust
will affect the performance of the appliance and cause
excessive electricity consumption.
When the Appliance is not in Use
When the appliance is not in use for long periods,
disconnect from the electricity supply, empty all foods
and clean the appliance, leaving the door open to
prevent unpleasant smells.
Defrosting
Bleeding part of the moisture of cooling chambers in
form of frost and ice goes with the operation of the
appliance.
Thick frost and ice has an insulating effect, so it
reduces cooling efficiency as the temperetaure
increases in the cooling chambers, they need more
energy.
This appliance automatically defrosts the cooling
surface of the refrigerator without any external
intervention. The termostatic control interrupts the
operation of compressor at regular intervals for more
or less time - during this cooling is interrupted - the
temperature of the cooling surface goes above 0°C
due to interior heating load of the compartment, so
defrosting occurs. When the surface temperature of
the cooling surface has reached +3 - +4°C the
thermostatic control restarts operation of the system.
