Cornelius R-404A REFRIGERANT Preparation for Operation, Turning on Electrical Power to Unit

PREPARATION FOR OPERATION

TURNING ON ELECTRICAL POWER TO UNIT

Turn on electrical power to the Unit. Operational status of the Unit is now being displayed as fault messages on the control panel message display. The following fault messages will be continuously displayed at 2-second inter- vals until necessary operation requirements are satisfied.

‘‘OFF 1’’ (Beater Motor No. 1 not operating) ‘‘OFF 2’’ (Beater Motor No. 2 not operating) ‘‘H2O OUT’’ (No water supply to Unit)

‘‘CO2 OUT’’ (No CO2 gas supply to Unit)

‘‘SYRUP 1’’ (No syrup supply to Unit No. 1 syrup system) ‘‘SYRUP 2’’ (No syrup supply to Unit No. 2 syrup system)

TURNING ON CO2 SUPPLY TO the UNIT

1.Open CO2 cylinder valve slightly to allow lines to slowly fill with gas, then open valve fully to backseat valve. Back-seating valve prevents leakage around valve shaft.

ADJUSTING PRIMARY CO2 REGULATOR

IMPORTANT: If bag-in-box syrup supply system will be connected to the Unit instead of soft drink tanks, primary CO2 regulator (see Figure 2) must be adjusted to no less than 80-psi.

1.Adjust primary CO2 regulator (see Figure 2) by turning regulator adjusting screw to the right (clockwise) until regulator pressure reads 80 to 100-psig.“OUT OF CO2 ” warning light on control panel message display should have gone out.

2.Using a flat blade screwdriver, turn lock counterclockwise to unlock the front access door (see Figure 5), then open the door for access to the product blender tanks relief valves

(see Figure 6).

3.Pull up on product blender tanks relief valves (see Figure 6) to purge air from tanks.

ADJUSTING PRODUCT BLENDER TANKS SECONDARY CO2

Check product blender tanks secondary CO2 regulators with 60-psi gages (see Figures 2 and 6) for pressure set- ting which should be set at 25 to 30-psi for best textured product. If further adjustment is necessary, adjust as instructed.

ADJUSTING CARBONATOR SECONDARY CO2 REGULATOR

IMPORTANT: The carbonator secondary CO2 regulator must be adjusted 25-psi higher or more above the product blender tanks secondary CO2 regulators pressure settings. Carbonated water and syrup pressures must be able to overcome and vent product blender tanks head pressures while tanks are filling with carbonated water and syrup. Carbonator tank secondary CO2 regulator not adjusted high enough will cause decreased flow of carbonated water into the blender tanks, which will increase brix of the dispensed product.

1.Adjust carbonator secondary CO2 regulator, with 100-psi gage, by turning regulator adjusting screw to the right (clockwise) until gage reads 50 to 60-psi.

2.Pull up on carbonator tank relief valve plastic cover to purge air from tank.
