(Section 14.34 continued from previous page.)
F. Syrup Transducer problem. F. Check syrup pressure readouts
for 70-72 psi . If not within 2 psi,
adjust regulator and/or check
transducer. Replace transducer, if
necessary.
G. Lower Board problem. G Test lower board for +5, +15, and
–15 outputs on lower board test
points (see Figure 14.3).
H. Upper Board Problem. H. Circuits within Main Control (Upper)
Board electronics read transducer
pressures. Replace Main Control
(Upper) Board, if necessary.
14.35 H20 Out A. Unit receiving no water. A. Assure water is turned on.
B. Restriction in lines. B. Assure all lines are free of crimps
or restrictions.
C. Regulator pressures (unit C. Check pressure readouts (H
2O and
water pump) too low or CO2 CO2) for 70-72 psi. Adjust
out. regulators, if necessary. Replenish
CO2 supply.
D. Water Pump failure. D. Check pump and replace, if
necessary.
E. Water pressure too low, E. Reroute water to maximize supply
can’t keep up with unit pressure. Install Water Booster, if
demand. necessary.
F. Water Transducer problem. F. Check water pressure readout for
70-72 psi. If not within 2 psi, adjust
regulator and/or check transducer.
Replace transducer, if necessary.
G. Lower Board problem. G. Test lower board for +5, +15, and
–15 outputs on lower board test
points (see Figure 14.3).
H. Upper Board Problem. H. Circuits within Main Control (Upper)
Board electronics read transducer
pressures. Replace Main Control
(Upper) Board, if necessary.
14.36 CO2 Out A. Unit receiving no CO2. A. Assure CO2 supply is not empty or
turned off.
B. Restriction in lines. B. Assure all lines are free of crimps
or restrictions.
C. Regulator pressures (to unit C. Check pressure readout ( CO2) for
and syrup pumps) too low. 70-75 psi (483.0-517.5 KPa).
Adjust regulators, if necessary.
D. CO2 can’t keep up with D. Reroute CO2 lines to maximize
unit demand. supply pressure or supply unit
dedicated CO2 source. Bulk
regulator must be 105 psi (723.9
KPa) minimum, CO2 line must be
tied to main branch of bulk system,
with step down regulator [set 70-
75 psi (483.0-517.5 KPa)] between
tie-in and unit.
E. CO2 Transducer problem. E. Check CO2 pressure readout for
70-75 psi (483.0-517.5 KPa). If not
within 2 psi, adjust regulator and/or
check transducer. Replace
transducer, if necessary.
F. Lower Board problem. F. Test lower board for +5, +15, and
–15 outputs on lower board test
points (see Figure 14.3).
