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)
‘‘H

O OUT’’ (No water supply to Unit)
‘‘CO

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 CO

SUPPLY TO the UNIT
1. Open CO
2
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.

REGULATOR
IMPORTANT: If bag-in-box syrup supply system will be connected to the Unit instead of soft drink tanks,
primary CO
2
regulator (see Figure 2) must be adjusted to no less than 80-psi.
1. Adjust primary CO
2
regulator (see Figure 2) by turning regulator adjusting screw to the right (clockwise) until
regulator pressure reads 80 to 100-psig.“OUT OF CO

” 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 CO
2
Check product blender tanks secondary CO
2
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 CO
2
REGULATOR
IMPORTANT: The carbonator secondary CO
2
regulator must be adjusted 25-psi higher or more above the
product blender tanks secondary CO
2
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 CO
2
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 CO
2
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.
