PREPARATION FOR OPERATION
TURNING ON ELECTRICAL POWER TO UNIT
Turn on electrical power to Unit. Operational status of Unit is now being displayed as fault messages on control
panel message display. The following fault messages will be continuously displayed at 2-second intervals until
necessary operation requirements are satisfied.
‘‘OFF 1’’ (Beater Motor No. 1 not operating)
‘‘OFF 2’’ (Beater Motor No. 2 not operating)
‘‘H
2
O OUT’’ (No water supply to Unit)
‘‘CO
2
OUT’’ (No CO
2
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
2
SUPPLY TO UNIT
1. Open CO
2
cylinder valve slightly to allow lines to slowly fill with gas, then open valve fully to back seat
valve. Back-seating valve prevents leakage around valve shaft.
IMPORTANT: If bag-in-box syrup supply system will be connected to Unit instead of soft drink tanks,
primary CO
2
regulator (see applicable Figure 2 or 3) must be adjusted to no less than 80-PSI.
2. For soft drink tanks installation (see applicable Figure 2 or 3), adjust primary CO
2
regulator by turning
regulator adjusting screw to the right (clockwise) until regulator pressure reads 80 to 100 psig. OUT OF
CO
2
warning light on control panel message display should have gone out.
3. Pull up on product blender tanks relief valves to purge air from tanks.
4. Remove Unit lower stainless steel access panel as instructed for access to carbonator secondary CO
2
regulators (see applicable Figure 2 or 3 and 7).
5. Check product blender tanks secondary CO
2
regulators with 60 psi gages for pressure setting which
should be set at 25 to 30 psi for best textured product. If further adjustment is necessary, adjust as
instructed.
IMPORTANT: Carbonator(s) secondary CO
2
regulator(s) must be adjusted 25 psi higher or more above
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(s) tank(s) secondary CO
2
regulator(s) not adjusted
high enough will cause decreased flow of carbonated water into blender tanks which will increase brix
of dispensed product.
6. Adjust carbonator(s) secondary CO
2
regulator(s), with 100 psi gage(s), by turning regulator(s) adjusting
screw(s) to the right (clockwise) until gage(s) reads 50 to 60 psi.
7. Pull up on carbonator(s) tank(s) relief valve(s) plastic cover(s) to purge air from tank(s).
TURNING ON CITY PLAIN WATER SOURCE LINE TO UNIT
City Plain Water Source Line Connected to Unit Post-Mix System (Water-Cooled and Air-Cooled Refrigeration
Units).
Open shutoff valve in City plain water line connected to the Unit Post-mix system. Check for water leaks and
tighten or repair if evident. ‘‘H
2
O OUT’’ fault message should have gone out but ‘‘SYRUP 1’’, and ‘‘SYRUP 2’’
fault messages will continue to be displayed.
City Plain Water Source Line Connected to Unit With Water-Cooled Refrigeration System.
Open shutoff valve in City water line connected to the refrigeration cooling coil (two-flavor Unit) or two
refrigeration cooling coils (four-flavor Unit). Check for water leaks and tighten or repair if evident.
