Setting Pressures
PRE-MIX PRESSURES
Normal pre-mix pressure regulators must be set at
60 psi (4.14 bar). Diet pre-mix pressure regulators
must be set at 40 psi (2.76 bar). If you are
experiencing high foaming, decreasing the pressures
may correct the problem. Spitting and popping usually
requires slightly increasing the pressures. Pre-mix
beverage valve pressures vary by type and
manufacturer. Please consult the manufacturer of the
valves you are using for specific instructions regarding
operation of the valve.
COLD CARB AND AMBIENT SYSTEM PRESSURES
1. Incoming tap water — must be at a minimum
dynamic pressure of 40 psi (2.76 bar) and
maximum static pressure of 65 psi (4.48 bar)
(measured at inlet to pump).
2. B-I-B pressure gauge must be set for a minimum
of 60 psi (4.14 bar) or according to your line run.
3. Carbonator Pressure gauge (Use Preset
Regulator):
- Cold Carbonation set for 75 psi (5.17 bar).
- Ambient systems must be set at 90 psi to
105 psi (6.20 bar to 7.24 bar).
Important
If incoming water pressure is under 40 psi
(2.76 bar), a water booster is recommended. If
incoming water pressure is over 65 psi (4.48 bar),
a water regulating valve is required.
