Operation (continued)
The condenser is located
behind the refrigerator and
can be cleaned by using a bot-
tle brush and brushing verti-
cally from top to bottom on
the face of the condenser. An
alternative method is to vac-
uum the condenser.
Ventilation
All refrigerators, regardless of the make, are heat-
transfer machines. They transfer the heat from the inside
of the fridge to the outside of the fridge. If adequate ven-
tilation is provided, the compressor will operate more
efficiently, and use less
power.
The minimum total area
required for ventilation
openings depends on the
size of the fridge. All single
door Nova Kools require 60
square inches of total venti-
lation area. It is recom-
mended that the vents are
located at the bottom (30
square inches) and the top
of the fridge (30 square
inches); this supports the
natural convection of heat
from cold (bottom) to warm
(top).
