Electricity with Household Appliances - Freezer
Freezers and refrigerators
operate most efficiently when filled to the capacity
recommended by the manufacturers. Never forget that only
one-tenth of a freezer's capacity should be used for
freezing of fresh food at any one time. The freezer must
work harder to remove heat, and uses more power. Example, 28
litrers (one cubic foot) will store 12,5 to 15 kg (25-30
lbs.) of frozen food and will freeze about 1,5 kg (3 lbs.)
of fresh food at a time. Food to be frozen should be placed
in contact with those parts of the freezer that contain the
refrigerant tubes, usually the sides of chest models.
 Defrosting
of chest type freezers should be done once or twice a year.
For upright models, defrosting should be done two or three
times a year. NEVER allow frost build up to exceed 0,6 to
1,3 cm.
By keeping a list of the location of foods in the freezers,
the freezer can be kept open for a minimum of time,
preventing the loss of cold air.
The freezer should be kept as full as possible to prevent
heavy icing. On all models keep condenser panels at the rear
of the freezer clean and dust free for maximum efficiency
and conservation of energy.
A second freezer should only
be operated when necessary.
In a single door unit, it is essential that the separate
freezer compartment has its own door intact. Otherwise the
unit will tend to operate the whole of the refrigerator as a
freezer - this can be expensive.
