CONVECTION COOLING
This unit is equipped with an advanced convection
cooling system. Convection cooling stabilizes cabinet
temperature, cools product faster and increases
energy efficiency.
Evaporator Fan
The evaporator fan is responsible for circulating warm
air from the refrigeration zone, past the evaporator
and back into the refrigerated zone.
The evaporator fan is factory set to have a 1 minute
delay at the beginning of a cooling cycle. This delay
gives the evaporator time to cool properly before
warm air is passed over it. The fan will continue to run
for an additional 2 minutes at the end of a cooling
cycle.
Evaporator fan operation is also determined by door
switch state. If the door switch circuit opens, the fan
will stop. When the door switch circuit is closed the
fan will either continue running with the cooling cycle,
or if not currently cooling, the fan will run for 1
minute to circulate air and clear any condensation
that may have appeared on glass doors and shelves.
Note:
If the unit is set to sabbath mode, the
evaporator fan will no longer respond to the state of
the door switch.
In order to operate efficiently, the evaporator fan
blade and vents should be unobstructed and free of
any dust buildup.
