INLET C02 PRESSURE TO CARBONATION SYSTEM SHOULD NOT EXCEED 75 PSI
LOW-PRESSURE C02 REGULATOR
The low-pressure C02 regulator setting can and will vary dramatically from one installation to
the next. Variables such as distance from syrup containers to point of serving, horizontal or
vertical runs, baume of product, to whether B.I.B. or transfer tanks are used will influence where
the low-pressure regulator is adjusted.
A good starting point as an adjustment is:
40 psi for B.I.B.
and
30 psi for transfer tanks.
NOTE:
After primary adjustment on low-pressure regulator always go to
farthest serving station from syrup storage area and adjust heaviest baume syrup
(normally ORANGE). If adjustment can be made proceed with all other flavors.
DIET SYRUP TANK C02 REGULATOR S-121
The diet C02 regulator is normally used only on transfer tank installations and should be set
from 6 to 10 psi depending on length of run. In some cases where a vertical run is encountered
pressure may be set as high as 15 psi. Excessive C02 pressure may cause diet syrup to
carbonate resulting in foam.
