CONVECTION COOLING
This unit is equipped with an advanced convection cooling
system. Convection cooling stabilizes cabinet temperature,
cools product faster, and increases energy eciency.
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. Fan delay times can
be modied through the service menu.
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.
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 eciently, the evaporator fan blade
and vents should be unobstructed and free of any dust
buildup.
