necessary.
E. CO
2 or water can’t keep up E. Reroute water or CO2 lines to
with unit demand. maximize supply pressure. Install
Water Booster if necessary.
F. Excessive pressure drops F. Observe “Syrup Press” readouts
in syrup lines. as chamber fills to verify. Increase
line diameter or relocate syrup
source closer to unit. Syrup
pressures may only be raised (by
increasing pump CO2 pressure)
if separate regulators are installed
for unit and syrup pumps. Never
exceed pump manufacturer’s
recommended maximum CO2 inlet
pressure (see Section 12.4).
G. Transducer problem (H2O, G. Check pressure readouts (H2O,
CO2 or Syrup). CO2 and Syrup) for 70-72 psig. If
not within 2 psi, adjust regulator
and/or check transducer. Replace
transducer, if necessary.
H. Lower Board problem H. Check Lower Power Board for +5,
+15, and –15 indicator lights. If
green lights are not energized,
replace board, if necessary.
I. Upper Board Problem I. Circuits within Main Control (Upper)
Board electronics read transducer
pressures. Replace Main Control
