PROBLEM
Compressor runs but will not cool
(With adjustment Board L.E.D.s
flashing 3, or 4 times every 4
seconds) (cont.)
Product Won’t Freeze
Product freezes but ice granules are
too fine or too large
Dispenser is making unusual noises.
(Some noises are a normal occurance
with this type of device. You need to

normal, to determine when they have
become unusual.)
PROBABLE CAUSE
2. Air Filter or Condenser
3. Refrigerant
1. DAY/NIGHT Switch
2. Sugar content of product
3. Voltage Divider
1. Ice adjustment
2. Sugar content of product
1. Lubrication
2. Cooling Drum(s)
REMEDY
The air filter and condenser MUST be
cleaned regularly. Any dust buildup
will affect cooling ability.
Have a qualified service person check
the refrigerant charge.
(A) The DAY/NIGHT Switch must be
in the “DAY” position.
(B) Refer to Service - DAY/NIGHT
Switch for testing procedures. See
page 36.
Bunn recommends the use of prod-
ucts with an apparent brix of 12 or
higher.
Refer to Service - Voltage Divider for
testing procedures. See page 50.
Turn the Ice control for the desired
hopper a small amount clockwise
to increase the ice granule size or
counterclockwise to decrease the
ice granule size.
Adjust the sugar content of the
product. Increasing the apparent
brix results in finer ice granules.
Decreasing the apparent brix results
in larger ice granules.
Always lubricate the dispenser as
directed in this manual before reas-
sembling and using the dispenser.
Use the cooling drum support to
determine that the auger shaft is still
the proper distance from the hopper
drip tray. The cooling drum may be
gently lifted to return it to the nec-
essary horizontal position. Refer to
Service - Cooling Drum Alignment.
