REMEDY
A. Tighten appropriately.
B. Replace or adjust appropriate
o-rings.
A. Verify incoming supply pressure
is correct.
A. Correct prior to dispenser.
Consider larger dispenser or
pre-cooler.
B. Readjust.
C. Bleed air from lines.
D. Check quality of ice used in drink.
E. Check refrigeration system.
A. Replace compressor relay or
overload.
B. Measure voltage across common
and run terminal on compressor.
Voltage must not drop below 90%
of rated voltage.
C. Refer to wiring diagram and correct.
D. Replace compressor.
A. Replace ice bank control.
B. Refer to wiring diagram and correct.
A. Measure voltage across common
and run terminal on compressor.
Voltage must not drop below 90%
of rated voltage.
B. Refer to wiring diagram and correct.
C. Replace starting relay. Be sure to
use correct relay. Failure to use
correct relay will cause compressor
failure.
D. Replace compressor.
A. Measure voltage across common
and run terminal on compressor.
B. Refer to wiring diagram and correct.
C. Replace starting relay. Be sure to
use correct relay. Failure to use
correct relay will cause compressor
failure.
A. Clean the condenser.
for minimum clearance of
15 inches (38.1 cm) over top.
C. Measure voltage across common
and run terminal on compressor.
Voltage must not drop below 90%
of rated voltage.
D. Refer to wiring diagram and correct.
F. Repair and recharge.
G. Replace compressor.
