Secondary Regulator (Syrup Regulator)
Function of the secondary regulator
Regulates the CO2 or air pressure used to push the syrups to the dispensing valves.
Failure of the secondary regulator
Low pressure or a sluggish regulator will cause an insufficient supply of syrup during
dispensing, resulting in drinks that taste over carbonated (fast dispersing foam).
High pressure or a creeping regulator will cause increased supply of syrup during dispensing,
resulting in drinks that taste flat and under carbonated (slow lingering foam).
Notes:
w Check for leaks with bubble soap (always rinse soap from tubing).
w Cartridge could cause pressure to decrease, diaphragm could cause increase
w Sticking check/relief valve can cause lower pressure to a tank or allow syrup to back up
into the regulator (remove front of regulator, check for syrup - can be cleaned with
warm water)
w To increase pressure, turn clockwise
w Syrup tank disconnect not properly seated or defective could cause restriction
w Letting syrup tanks to empty or a
defective leaking syrup disconnect
will cause air in the lines and
foaming at the dispensing valve
(especially at the slab stores with
underground chases).
w To clear activate both valves at
once until air clears.
w When jumping syrup tanks, always
put the new thank on the front
(syrup feed side) and move the
partial tank to the back (gas feed
side).
