WATER-TO-SYRUP ‘‘RATIO’’. A. Dirty or inoperative dispensing
valve syrup flow control. A. Disassemble and clean
dispensing valve syrup flow
control.
DISPENSED PRODUCT
CARBONATION TOO LOW. A. Carbonator CO
2
regulator out
of adjustment for existing
water conditions or
temperature.
A. Adjust carbonator CO
2
regulator
(Reference manual provided with
carbonator).
B. Air in carbonated water tank. B. Vent air out of carbonated water
tank by dispensing from
dispensing valve to make
carbonator water pump motor
cycle on.
C. Water, oil, or dirt, in CO
2
supply.
C. Remove contaminated CO

before using. (Refer to following
NOTE.)
NOTE: Crushed ice also causes dispensing problems. When finished drink hits sharp edges of ice,
carbonation is released from dispensed drink.
DISPENSED PRODUCT
PRODUCES FOAM AS IT
LEAVES DISPENSING VALVE. A. Recovery rate of refrigeration
unit exceeded, ice bank
depleted. A. Allow ice bank to recover.
CAUTION: The refrigeration assembly condenser coil must be
cleaned every 30-days. Excessive accumulation of dust, lint, and
grease on the condenser coil will restrict cooling air flow through
coil and cause refrigeration system to overheat. Operating
refrigeration system in an overheated condition will eventually
lead to refrigeration compressor failure and will automatically void
the factory warranty.
B. Condenser coil plugged. B. Clean condenser coil as
instructed.
C. Carbonator CO
2
regulator
pressure too high for existing
water conditions or
temperature.
C. Reduce carbonator CO
2
regulator
pressure setting.
D. Dispensing valve restricted or
dirty. D. Sanitize syrup system as
instructed.
E. Tapered gasket inside
carbonated water line swivel
nut connector distorted
restricting carbonated water
flow. E. Replace tapered gasket. Make
