Carbonation Level in Liquid Product Affects Overrun.
The higher the specific carbonation level in a given product, the greater the potential for carbonation breakout in
frozen carbonated form of that drink. For example, drinks with 3.0 volume of carbonation will have more gas
breakout in frozen carbonated form, and more overrun, than will drinks that contain 2.0 volumes of CO
Freezing Affects Overrun.
Freezing causes approximately a 10 percent expansion in dispensed frozen carbonated drinks. 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
from a high overrun light drink to a wet, heavy drink. The length of freezing cycle and amount of CO
product combine to create the drink dispensed. The dispensed product will have a normal variance due to the
following conditions:
1. If some time has elapsed since last drink was drawn from particular freeze cylinder and compressor 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 drink described above by adjusting viscosity.
2. If product is drawn from freeze cylinder quite regularly, its viscosity (product consistency) will be maintained
at whatever viscosity adjustment was made within the normal variance of the compressor off and on cycle.
See Drawing 2.
3. If product is drawn continuously from freeze cylinder and rate is approaching capacity of the dispensing
unit, overrun of drink will increase just prior to point capacity is exceeded, and drink dispensed will turn
slightly wetter. See Drawing 3.

OPERATING UNIT

NOTE: The No. 1 freeze cylinder (see Figure 5) is the left-hand cylinder facing the front of the Unit. No.
2 freeze cylinder is to the right of No. 1 freeze cylinder.
1. Make sure ''H O OUT'' fault message is not displayed on message display. This indicates no water supply
2
to Unit.
2. Make sure ''CO OUT'' fault message is not displayed on message display. This indicates no CO
2
supply to Unit.
3. Make sure ''SYRUP 1'' or ''SYRUP 2'' fault messages are not displayed on message display. This indicates
no syrup supply to Unit.
4. Make sure ''AUTO BLEND 1'', ''AUTO BLEND 2'', ''AUTO 1'', and ''AUTO 2'' control switches are pressed
for normal operation.
5. Place cup under dispensing valve, then dispense until cup is full of product.
6. Make sure viscosity (product consistency) is as desired. If not, adjust as instructed.
