Faceplate Relief Valves; Product Sample Valves; Product Shutoff Valves; Primary Co2 Regulator - Cornelius 326142000 Service Manual

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 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
2
cylinder to atmosphere during filling with product and if gas pockets form in cylinder during operation.

PRODUCT SAMPLE VALVES

The two product sample valves (see Figures 2 and 6), located behind front lower access panel, 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 product blender tanks to freeze cylinders (see
Figures 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
cylinder.
PRIMARY CO REGULATOR
2
The primary CO regulator (see Figure 2) controls CO pressure to soft drink tanks and Unit secondary CO
2 2 2
regulators located behind lower front access panel. If necessary to adjust primary CO regulator, adjust as
2
instructed.
SECONDARY CO REGULATORS
2
The three secondary CO regulators, located behind lower front access panel (see Figures 2 and 6), control
2
CO pressure to carbonator and product blender tanks. If necessary to adjust secondary CO regulators, adjust
2 2
as instructed.

CARBONATED WATER FLOW REGULATORS

The adjustable carbonated water flow regulators (see Figures 2 and 6), located in their respective systems,
control carbonated water flow rate to the product blender tanks. The water flow regulators are factory adjusted
at 1.5 0.05 oz/sec and should not normally require adjustment. If adjustment is necessary, adjust as
instructed.

SYRUP FLOW REGULATORS

The syrup flow regulators (see Figures 2 and 6), located in their respective systems, are adjustable regulators
that control syrup flow rate to the product blender tanks for desired BRIX of dispensed product. Adjust syrup
flow regulators for desired BRIX as instructed.

DISPENSING VALVES

Self-closing dispensing valves (see Figure 5 and 7), located on faceplates on front of Unit, are operated one at
a time or simultaneously to deliver product to the customer.

DISPENSED PRODUCT CONDITIONS

''OVERRUN'', AS APPLIED TO FROZEN CARBONATED BEVERAGES

Overrun Defined.
Overrun is product expansion that takes place in the frozen carbonated drink. It is caused primarily by CO gas
2
breakout and secondary by freezing.
