TOP (WARM) ZONE
If the vendor is a Dual Zone, then the trays above the barrier are in the
Top (Warm) Zone. If the
optional heater system is installed, then an optional temperature
SENSOR2
is also installed.
The optional heater is inside the air duct located on the back of the cabinet. An optional blower
fan is located on the top corner above the heater. The blower is turned on if the temperature is
outside of the setting (
SET POINT
plus or minus half of
DELTA
).
CUT-IN
The heater turns on when
SENSOR2
temperature is less than or equal to
SET POINT
minus half
of
DELTA
.
CUT-OUT
The heater turns off if
SENSOR2
reading equals the
SET POINT
or if the compressor is on.
REFRIGERATION
To prevent damage to the refrigeration unit when it is turned off or the power is interrupted, the refrigeration unit will not restart
for at least three minutes regardless of the temperature.
REFRIGERATION TROUBLESHOOTING
CAUTION
:
Breaking the refrigerant joints or seals on the system voids the unit warranty. Failure to keep the
condenser coil clean and free of dirt and dust and other similar debris voids the unit warranty.
Know and understand how the unit operates. Units may vary, but the operation is basically the same. Never guess at the problem; find
the symptom before attempting any repair.
NOTE: MOST REFRIGERATION PROBLEMS ARE ELECTRICAL.
WARNING:
Wiring diagrams must be followed as shown. Wrong wiring may cause serious electrical hazard and potential
damage or rupture component electrical parts.
