Cornelius R-404A REFRIGERANT ‘‘SLEEP’’ Sleep Time Operation, Faceplate Relief Valves

‘‘SLEEP’’ (SLEEP TIME) OPERATION

‘‘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 5), 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 CO2 gas from freeze cylinder to atmosphere during filling with product and if gas pockets form in cylinder during op- eration.

PRODUCT SAMPLE VALVES

The two product sample valves are located behind the lower front access panel (see Figure 2 and Figure 6) 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 90° angle with line to close valve.

PRODUCT SHUTOFF VALVES

The two product shutoff valves, located in lines leading from the product blender tanks to the freeze cylinders (see Figure 2 and 6), 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 cylinders.

PRIMARY CO2 REGULATOR

The primary CO2 regulator (see Figure 2) controls CO2 pressure to the soft drink tanks and the Unit secondary CO2 regulators located behind the lower front access panel. If necessary to adjust the primary CO2 regulator, adjust as instructed in the SERVICE AND MAINTENANCE section.

SECONDARY CO2 REGULATORS

The secondary CO2 regulators, located behind the lower front access panel (see Figure 2 and 6), control CO2 pressure to the carbonator and the product blender tanks. If necessary to adjust the secondary CO2 regulators, adjust as instructed in the SERVICE AND MAINTENANCE section.

CARBONATED WATER FLOW REGULATORS

The adjustable carbonated water flow regulators, (see Figure 2 and 12) located behind the front access panel, 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.
