Preparation For Operation; Turning On Electrical Power To Unit; Turning On Co2 Supply To The Unit; Adjusting Primary Co2 Regulator - Cornelius FCB OVERCOUNTER POST-MIX DISPENSER Service Manual

1. Remove cover from electrical box located in lower back side of the Unit.
WARNING: The Unit must be electrically grounded to avoid possible fatal electrical shock
or serious injury to the operator. A green screw, with lock washer, is provided inside the
electrical box to connect power circuit ground wire which will electrically ground the Unit.
2. Connect electrical power circuit from a 30-amp (60-Hz Unit) or 30-amps (50-Hz Unit) minimum-rated discon-
nect switch (not provided) fused at 30-amps (60- Hz Unit) or 30-amps (50-Hz Unit) (slow-blow) or through an
equivalent HACR circuit breaker to electrical wires inside the electrical control box. Secure the connections
with red wire nuts. MAKE SURE GROUND WIRE IS CONNECTED TO GREEN GROUND SCREW INSIDE
THE ELECTRICAL BOX.
3. Install the electrical box cover and secure with screws.

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

2. Using a flat blade screwdriver, turn lock counterclockwise to unlock the front access door (see Figure 7),
then open the door for access to the product blender tanks relief valves (see Figure 8).
3. Pull up on product blender tanks relief valves (see Figure 8) to purge air from tanks.
ADJUSTING PRODUCT BLENDER TANKS SECONDARY CO
Check product blender tanks secondary CO
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
IMPORTANT: The carbonator secondary CO
product blender tanks secondary CO
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
enough will cause decreased flow of carbonated water into the blender tanks, which will increase brix of
the dispensed product.
