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. Fan delay times can 

be modified 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 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.

Evaporator Fan Replacement

steps below.

1.  Remove any product from the unit.

12.  While pulling the evaporator cover clear of the unit, it
