Automatic Electric Defrost System.
The automatic electric defrost system may be programmed into the Unit to occur up to nine different times a day
with a minimum of two hours between defrost settings. At start of each automatic electric defrost cycle, the re-
frigeration compressor will operate for a short time. No.1 freeze cylinder only will go into defrost cycle and de-
frost for approximately 15-minutes, then the Unit will return to normal operation. This ends the automatic defrost
cycle of No.1 freeze cylinder. No. 2 freeze cylinder will defrost 30-minutes after the start of No. 1 freeze cylinder.
The next automatic electric defrost cycle will occur according to the time programmed into the Unit.
‘‘SLEEP’’ (SLEEP TIME)
UNITS EQUIPPED WITH HOT-GAS DEFROST SYSTEMS
NOTE: The following paragraph describes “SLEEP” (SLEEP TIME) operation for the Two-Flavor and the
Four-Flavor FCB Dispensers No. 1 and No. 2 freeze cylinders. The “SLEEP” (SLEEP TIME) operation for
the Four-Flavor FCB Dispenser No. 11 and No. 22 freeze cylinders is identical to the No. 1 and No. 2
freeze cylinders.
‘‘SLEEP’’ (SLEEP TIME) may be programmed into Unit to allow the Unit to go into sleep time (Unit shut down,
freeze cylinders beaters and refrigeration systems not operating). At start of sleep time, the refrigeration com-
pressor will operate for 30 seconds to pump freon out of the freeze cylinders evaporator coils, then No. 1 freeze
cylinder will go into defrost and defrost for 60 seconds. After No. 1 freeze cylinder has defrosted, No. 2 freeze
cylinder will go into defrost and defrost for 60 seconds. At end of the No. 2 freeze cylinder defrost, Unit will shut
down and go into sleep time. The ‘‘SLEEP’’ (SLEEP TIME) operation for the Four-Flavor FCB Dispenser No. 11
and No. 22 freeze cylinders is identical to the No. 1 and No. 2 freeze cylinders.
UNITS EQUIPPED WITH ELECTRIC DEFROST SYSTEMS
‘‘SLEEP’’ (SLEEP TIME) may be programmed into Unit to allow the Unit to go into sleep time (Unit shut down,
freeze cylinders beaters and refrigeration systems not operating). At start of sleep time, the refrigeration com-
pressor will operate for 30 seconds to pump freon out of the freeze cylinders evaporator coils, then both freeze
cylinders will simultaneously go into defrost and defrost for approximately 15-minutes. At end of the defrost
cycle, the Unit will 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 the
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, located in each freeze cylinder faceplate (see Figure 3), are spring-loaded valves
that protect the freeze cylinders from accidental over-pressure. The relief valve is also used to manually bleed
CO
2
gas from the freeze cylinder to atmosphere during filling with product and if gas pockets form in the cylin-
der during operation.
DISPENSING VALVES
Self-closing dispensing valves, located on the faceplates on front of the Unit (see Figure 3), are operated one at
a time or simultaneously to deliver product to the customer.
