TROUBLE
CAUSE
REMEDY
High head/suction pressure.
Condenser air flow restricted.
Check for air flow restriction, clean
condenser and air filter.
Compressor damage.
Check amp draw on compressor.
High ambient temperature.
Temperature surrounding unit
should be less than 90°F (32°C).
Low head/suction pressure.
Low refrigerant level.
See solution for "Compressor runs
for a long time."
Caution: Do not pressurize low side (evaporator and compressor suction) above 150 psig (1,034 kPag)
for any reason. Components will fail and warraties will be void.
11.4 Drink Quality
TROUBLE
CAUSE
REMEDY
Drink to "wet" or "liquid."
Barrel not filled properly.
Defrost, then ensure barrel is filled
to 90% capacity.
CO
2
check valve clogged.
Clean or replace check valve.
CO
2
level in drink too low.
1. To affect ALL barrels, raise
"primary CO2" within 70-72
psig (483-496 kPag) range.
2. To affect ONE barrel, adjust
secondary CO
2
regulator for
that barrel inside of the dis-
penser to 58-62 psig (400-427
kPag).
CO
2
shutoff valve is off.
Open valve and refill barrel.
Secondary CO
2
regulator inside
of dispenser malfunctioning.
Check secondary regulator.
Repair or replace if necessary.
Incorrect brix or water/syrup flow
rates.
Check water and syrup flows and
adjust if necessary. Then check
brix (see
Section 6.4
).
"Tank Pressure" readout not mov-
ing between 18 and 40 psig (124
to 276 kPag) or doesn't lower
when barrel pressure is reduced.
Observe tank transducer, check
and replace if necessary.
CO
2
orifice is blocked.
Remove blockage.
Drink quality is too light.
Barrel not filled properly.
Defrost and assure barrel is filled
to 90% of capacity.
Incorrect brix or water/syrup flow
rates.
Check water and syrup flows and
adjust if necessary. Then check
brix (see
Section 6.4
).
