Sleep'' (Sleep Time); Wake Up'' (Wake Up Time); Faceplate Relief Valves; Product Sample Valves - Cornelius FCB POST-MIX DISPENSER Installation & Service Manual

''SLEEP'' (SLEEP TIME)

''SLEEP'' (SLEEP TIME) may be programmed into Unit to allow Unit to go into sleep time (Unit shut down,
freeze cylinders beaters and refrigeration systems not operating). At start of sleep time, refrigeration
compressor will operate for 30-seconds to pump freon out of freeze cylinders evaporator coils. Then No. 1
freeze cylinder will go into defrost for 60-seconds. After No. 1 freeze cylinder has defrosted, No. 2 freeze
cylinder will go into defrost for 60-seconds. At end of No. 2 freeze cylinder defrost, Unit will shut down and go
into sleep time.

''WAKE UP'' (WAKE UP TIME)

''WAKE UP'' (WAKE UP TIME) may be programmed into the Unit to allow Unit to resume normal operation at a
desired time. When programmed wake up time is reached, an alarm will sound for a short duration, then Unit
will resume normal operation.
NOTE: Automatic defrost, sleep time, and wake up time may be used in any combination together or
separately.

FACEPLATE RELIEF VALVES

The faceplate relief valves (see Figure 6), located in each freeze cylinder faceplate, are spring-loaded valves
that protect freeze cylinders from accidental over-pressure. The relief valve is also used to manually bleed CO
gas from freeze cylinder to atmosphere during filling with product and if gas pockets form in cylinder during
operation.

PRODUCT SAMPLE VALVES

The two product sample valves (two-flavor Units) or four product sample valves (four-flavor Units), are behind
the lower front access panel (see Figure 7) and are manually operated lever-type ball valves used to check
product Brix. Turn valve lever to line up with attached line to open valve and at a 90° angle with line to close the
valve.

PRODUCT SHUTOFF VALVES

The two product shutoff valves (two-flavor Unit) or four product shutoff valves (four-flavor Unit), located in lines
leading from the product blender tanks to the freeze cylinders (see applicable Figure 2 or 3 and 7), are manually
operated lever-type ball valves and are used to prevent product from entering and filling freeze cylinders while
adjusting Brix of dispensed product. Shutoff valves may also be used to shut off product to individual freeze
cylinder for service and maintenance without disrupting operation of other freeze cylinder.
PRIMARY CO REGULATOR

The primary CO regulator (see applicable Figure 2 or 3) controls CO
2
Unit secondary CO regulators located behind the lower front access panel. If necessary to adjust the primary
2
CO regulator, adjust as instructed in SERVICE AND MAINTENANCE section.
2
SECONDARY CO
The secondary CO regulators, located behind the lower front access panel (see applicable Figure 2 or 3 ),
2
control CO pressure to the carbonator and the product blender tanks. If necessary to adjust the secondary
2
CO regulators, adjust as instructed in the SERVICE AND MAINTENANCE section.

CARBONATED WATER FLOW REGULATORS

The adjustable carbonated water flow regulators (see applicable Figure 2 or 3), located in their respective
systems, control carbonated water flow rate to the product blender tanks. The water flow regulators are factory
adjusted at 1.3 ± 0.05 oz/sec. and should not normally require adjustment. If adjustment is necessary, adjust as
instructed in the SERVICE AND MAINTENANCE section.
