Freezing Affects Overrun.
Freezing causes approximately a 10 percent expansion in a dispensed frozen carbonated drink. The degree of
freezing is limited because the finished drink is intended to be sipped through a straw. This is not possible if the
product is too ‘‘solid’’.
OPERATING CHARACTERISTICS
The product viscosity (product consistency) can be varied by adjustment and secondary CO
2
regulator setting
from a high overrun light drink to a wet heavy drink. The length of the freezing cycle and the amount of CO
2
present in the product combine to create the drink dispensed. The dispensed product will have a normal vari-
ance due to the following conditions:
1. If some time has elapsed since the last drink was drawn from a particular freeze cylinder and the compres-
sor has not cycled on, the drink dispensed will have a tendency to be wetter, have slightly less overrun
than normal for the setting, and will not mound up as high. See Drawing 1.
NOTE: A cylinder freeze-up may be expected under casual draw conditions if an attempt is made to
eliminate the drink described above by adjusting viscosity.
2. If product is drawn from the freeze cylinder quite regularly, its viscosity (product consistency) will be main-
tained at whatever viscosity setting was made within the normal variance of the compressor off and on
cycle. See Drawing 2.
3. If product is drawn continuously from the freeze cylinder and the rate is approaching capacity of the dis-
pensing Unit, overrun of the drink will increase just prior to point capacity is exceeded, and drink dispensed
will turn slightly wetter (see Drawing 3).
OPERATING UNIT
NOTE: Two-flavor Unit- The No. 1 freeze cylinder is the left-hand cylinder facing the front of the Unit.
The No. 2 freeze cylinder is to the right of the No. 1 freeze cylinder.
Four-flavor Unit- The No. 1 freeze cylinder is the left-hand cylinder facing the front of the Unit. The oth-
er three freeze cylinders are labeled 2, 11, and 22.
1. Make sure ‘‘H
2
O OUT’’ fault message is not displayed on the message display. This indicates no water
supply to the Unit.
2. Make sure ‘‘CO
2
OUT’’ fault message is not displayed on message display. This indicates no CO
2
gas sup-
ply to Unit.
3. Make sure ‘‘SYRUP 1’’ or ‘‘SYRUP 2’’ fault messages are not displayed on the message display. This indi-
cates no syrup supply to the Unit.
4. Make sure both ‘‘BLEND ON/OFF’’ and both “ON” control switches are pressed for normal operation.
5. Place cup under the dispensing valve, then dispense until the cup is full of product.
6. Make sure viscosity (product consistency) is as desired. If not, adjust as instructed.

REGULATORS
PRIMARY CO
2
REGULATOR
The primary CO
2
regulator controls CO
2
pressure to the syrup tanks (syrup tanks syrup source system) or to
the syrup pumps (bag-in-box syrup source system). If adjustment of this CO
2
regulator should become neces-
sary, call a qualified Service Person to make the adjustment.
