Clean the condenser (black grill) and the com-
pressor at the back of the appliance with a
brush. This operation will improve the perform-
ance of the appliance and save electricity con-
sumption.
Important! Take care of not to damage the
cooling system.
Many proprietary kitchen surface cleaners con-
tain chemicals that can attack/damage the
plastics used in this appliance. For this reason
it is recommended that the outer casing of this
appliance is only cleaned with warm water with
a little washing-up liquid added.
After cleaning, reconnect the equipment to the
mains supply.
Defrosting of the refrigerator
Frost is automatically eliminated from the evap-
orator of the refrigerator compartment every
time the motor compressor stops, during nor-
mal use. The defrost water drains out through a
trough into a special container at the back of
the appliance, over the motor compressor,
where it evaporates.
It is important to periodically clean the defrost
water drain hole in the middle of the refrigerator
compartment channel to prevent the water
overflowing and dripping onto the food inside.
Use the special cleaner provided, which you
will find already inserted into the drain hole.
Defrosting the freezer
A certain amount of frost will always form
on the freezer shelves and around the top
compartment.

Important! Defrost the freezer when the frost
layer reaches a thickness of about 3-5 mm.
To remove the frost, do these steps:
1. Switch off the appliance.
2. Remove any stored food, wrap it in several
layers of newspaper and put it in a cool
place.
3. Leave the door open.
4. When defrosting is completed, dry the in-
terior thoroughly and refit the plug.
5. Switch on the appliance.
6. Set the temperature regulator to obtain the
maximum coldness and run the appliance
for two or three hours using this setting.
7. Reload the previously removed food into
the compartment.
Important! Never use sharp metal tools to
scrape off frost from the evaporator as you
could damage it. Do not use a mechanical
device or any artificial means to speed up the
thawing process other than those
recommended by the manufacturer. A
temperature rise of the frozen food packs,
during defrosting, may shorten their safe
storage life.
Periods of non-operation
When the appliance is not in use for long peri-
ods, take the following precautions:
• disconnect the appliance from electrici-
ty supply
• remove all food
• defrost (if foreseen) and clean the appliance
and all accessories
• leave the door/doors ajar to prevent unpleas-
ant smells.
If the cabinet will be kept on, ask somebody to
check it once in a while to prevent the food in-
side from spoiling in case of a power failure.
