To replace the fuses, follow these steps:

CLEANING

Always keep the refrigerator clean. Cleaning the refrigerator

is usually done after it is defrosted or put into storage. Use

lukewarm weak soda solution to clean the interior liner of the

refrigerator. Use warm water only to clean the ﬁ nned evapora-

tor, gasket, ice tray and shelves.

NOTE!

Never use strong chemicals or abrasives to clean these

parts, as the protective surfaces will be damaged. Do not spray

liquids near electrical outlets, connections or the refrigerator

components.

To keep the refrigerator operating efﬁ ciently and safely, peri-

odic inspection and cleaning of several components once or

twice a year is recommended:

Check the lower vent, upper vent and area between these

openings for any obstructions such as bird/insect nests,

spider webs, etc.

Make sure the refrigerator area is free from combustible

material, gasoline and other ﬂ ammable vapors or liquids.

Clean the coils on the back of the refrigerator. Use a soft

bristled brush to dust off the coils.

PRODUCT CARE

DEFROSTING

Shut off the refrigerator by pressing the main power

ON/OFF button (OFF position).

Empty the refrigerator.

Leave the cabinet and freezer doors open and place

the drip tray under the ﬁ nned evaporator.

Defrosting time can be reduced by ﬁ lling the ice

trays with hot water and placing them in the freezer

compartment.

When all the frost has melted, dry the interior with a

clean cloth.

Replace the food. Set the thermostat to the coldest

setting for a few hours. Then, reset the thermostat to

the desired setting, usually at mid setting.

lar schedule. Please note that this service should be performed by qualiﬁ ed service personnel only! The
