Cornelius R-404A REFRIGERANT service manual Adjusting Plain Water Pressure Regulator

15.Position SCRAPER BLADES (item 2) on BEATER (item 13) as shown in Figure 8. Slide beater into freeze cylinder so slotted hooks engage DRIVE PIN (item 17) on DRIVE SHAFT (item 19). Turn beater to the right (clockwise) to lock in place.

16.Lubricate O-RING (item 5) with water to facilitate faceplate installation. Position O-RING (item 5) on FACE- PLATE (item 8). Install faceplate on Unit so dispensing valve spout faces down. (MAKE SURE FEMALE END OF THE BEATER IS PLACED OVER THE FACEPLATE STAINLESS-STEEL STUD AND BUSHING BEFORE PUSHING THE FACEPLATE INTO POSITION ON ITS FOUR THREADED MOUNTING STUDS). Tighten hex nuts until faceplate touches freeze cylinder all around flange. CAUTION – DO NOT OVERTIGHTEN HEX NUTS.

17.Turn dispensing valve spring housing to the left (counterclockwise) to put tension on torsion spring, then tighten hold-down plates to secure spring housing.

18.Test dispensing valve to make sure it closes by itself when lever is released. If not, readjust torsion spring tension.

19.Sanitize syrup system as instructed in CLEANING AND SANITIZING, then return Unit to operation.

CLEANING CONDENSER COIL

(see Figure 6)

NOTE: The FCB Dispenser refrigeration system is equipped with a condenser coil (see Figure 6) that is cooled by two condenser coil fans. Circulating air, required to cool the refrigeration system’s condens- er coil, is drawn in through grilled panel on the right-hand side and is exhausted out through the oppo- site side and back grilled panels. Restricting air circulation through the Unit will decrease its cooling efficiency. THE CONDENSER COIL MUST BE CLEANED PERIODICALLY AS INSTRUCTED.

Periodically clean condenser coil as follows:

1.Press ‘‘OFF 1’’ and ‘‘OFF 2’’ switches on Unit control panel to stop refrigeration system and beaters mo- tors.

2.Remove Unit right-side panel as instructed.

3.Clean condenser coil with vacuum cleaner, low pressure compressed air, or a soft brush.

4.Install Unit right-side panel as instructed.

5.Press ‘‘AUTO 1’’ and ‘‘AUTO 2’’ switches on Unit control panel to start refrigeration system and beaters motors.

ADJUSTMENTS

ADJUSTING PLAIN WATER PRESSURE REGULATOR

(see Figure 2 and 12)

Carbonator(s) plain water inlet adjustable water pressure regulator is factory adjusted to 45-psi and should not be readjusted.

ADJUSTING CARBONATED WATER

FLOW RATE

The carbonated water flow regulators (see Figure 2 and 12), which control carbonated water flow rate into the product blender tanks, are factory adjusted for a flow rate of 1.3 ± 0.05 ounces per second and normally do not require adjustment. However, if adjustment is necessary, proceed as follows:
