b) Thermostatic Expan-
sion Valve
c) Refrigerant Lines
d) Compressor Motor
Protector
e) Inside wall of
Evaporator
a) Condenser
b) Fan Motor
a) Water supply
PROBLEM POSSIBLE CAUSE
1) Clean.
2) Remove anything blocking
vents.
1) Secure bulb to low-side
line or replace.
1) Check for leaks with a
leak detector. Reweld
leak, replace drier and
charge with refrigerant.
The amount of refrigerant
is marked on Nameplate.
2) Recharge.
1) Check Condenser and
Fan Motor.
1) Remove Auger, use
Hoshizaki “Scale Away”
or “LIME-A-WAY” solution
to clean periodically.
If water is found to sur-
pass the following levels,
install a conditioner:
Hardness 50 ppm
Silica 30 ppm
1) Clean.
2) Remove anything blocking
vents.
3) Check ventilation and
location, and change as
needed.
4) Allow proper clearance for
ventilation.
1) See chart 1 - [5] - a).
1) See chart 1 - [6] - a).
1) Dirty Air Filter or Condenser.
2) Bad ventilation.
1) Low-side pressure or tem-
perature exceeding the
limit.
1) Gas leaks.
2) Overcharged.
1) Overload Protector stops
Compressor intermittently.
1) Scale on inside wall of
Freezing Cylinder.
1) Dirty Air Filter or Condenser.
2) Bad ventilation.
3) Ambient temperature too
high.
4) Less than 6" clearance at
rear, sides and top.
1) Fan revolving too slowly.
1) Water pressure too low.
