Owner's Manual

INITIAL START UP CONTINUED
NOTE: If the evaporating temperature has not
dropped lower than 30° F within ten minutes of
compressor start-up, the evaporating temperature
sensor will detect the abnormal temperature and
stop the unit operation.
In this circumstance, the 3rd warning YELLOW
LED will blink (Fig.3).
After diagnosing and eliminating the cause of the
poor evaporating temperature (insufficient
refrigerant in the system, inoperative compressor
or inoperative evaporator sensor), push the
RESET BUTTON on the control board.
Before resuming operation the unit will go through
the usual 3 minute STAND-BY period.
OPERATION CHECKS UPON THE UNIT START
UP
D. Remove the service panels and (if needed)
connect the refrigerant service gauges to the
corresponding service valves to check both the HI
and LO refrigerant pressures.
NOTE:The condenser temperature sensor, which
is located within the condenser fins, keeps the
head (condensing) pressure between two preset
valves.
If proper flow of cooling are is prevented by a
clogged condenser or inoperative fan motor, the
condenser temperature rises. When it reaches
158° F the condenser temperature sensor
shuts-off the ice machine and turns on the 2nd
RED WARNING LIGHT (Fig.4).
