Grounding
•All fountain equipment with a Variety valve installed
must be properly grounded.
Grounding The Dispenser For Autofill Variety Valves
For proper operation of the Autofill Variety valve, follow the steps below to determine if the existing Optifill valves need
to be grounded.
NOTE: These steps are usually only need to be followed on retrofit applications.
•The 24 VAC valve power supply must be properly
grounded.
1. Turn on the power to the dispenser.
2. Disconnect the 24V power supply from an Optifill valve
adjacent to the Variety valve.
3. Check the voltage across the white wire of the
connector to the dispenser chassis. Check the voltage
across the black wire of the connector to the dispenser
chassis.
4. If the voltage across the white wire to the chassis is 2427 volts, the transformer is properly grounded. Proceed
with the Variety valve installation. If the voltage across
the black wire to the dispenser chassis is 24-27 volts,
reverse the load wires connected to the valve wire
harness as shown below and proceed with Variety valve
installation.
5. If the voltage across either the white or black wires to the
chassis is less than 24 volts, a grounding wire must be
installed on the transformer. Unplug the dispenser and
install the grounding wire on the transformer as shown
below.
6. After the grounding wire is installed, plug the dispenser
in and turn on the power. Recheck the voltage across
the white wire of the connector to the dispenser chassis
and across the black wire of the connector to the
dispenser chassis.
7. If the voltage across the white wire to the dispenser
chassis is 24-27 volts, proceed with the Variety valve
installation.
8. If the voltage across the black wire to the chassis is 2427 volts, reverse the load wires connected to the valve
wire harness and then proceed with Variety valve
installation.
9. After installing the Variety valve, check all valves to
make sure they all function properly.

Caution
RETROFIT INSTALLATION
The Variety valve may be retrofitted to nearly any softplumbed fountain dispenser.
1. Inspect the Variety Valve
Thoroughly inspect the Variety valve upon delivery.
Immediately report any damage that occurred during
transportation to the delivery carrier. Request a written
inspection report from a claims inspector to document any
necessary claim. Make sure the following components are
available to install the valve:
ComponentQuantity
Var ie ty val ve1
Mounting block1
Retrofit plate kit1
90° short dole fitting2
90° long dole fitting2
90° bends2
Installation and service manual1
3/8 in × 1/4 in splicer2
Oetiker clamps (13.3 mm or 11.3 mm)*8
Sheet metal screws4
*Size depends on tubing brand. Always use the
manufacturer’s recommended hose clamp size.
NOTE: A knockout tool is required for installation and is
not provided with the Variety valve.
2. Prepare the Site
A. Make sure the following equipment/supplies are
available before starting the installation:
ComponentQuantity
BIB pumps (Shurflo pumps are
recommended)
BIB connectors2
Space for 2 extra BIB bags or an additional
BIB rack
3/8 in BIB tubingAs needed
3/8 in standard beverage line for non-chilled
syrup (Bev-Ultra Seal)
1/4 in flexible tubingAs needed
Socket wrench1
1 1/8 in socket1
Phillips screwdriver1
Safety glasses1
Alcohol wipes or rubbing alcoholAs needed
Oetiker pliers1
Tube cutter1
UF-1 syrup separator1
Pepsi brix cup1
Food grade lubricantAs needed
Knockout tool kit1
NOTE: Make sure that high
movers are placed on the lower
2
section of the rack.
As needed
B. Verify the plain water pressure is not too high or
too low.
• Too high—If the plain water pressure is ≥60 psig,
install a pressure regulator in the back room
where the plain water line branches out.
• Too low—Use one of the following methods to
check for low water pressure:
- Open the plain water valve and a carbonated
water valve at the same time. When the
carbonator pump turns on, read the pressure
gauge. If the pressure is <35 psig, a dedicated
plain water line is necessary.
- If a pressure gauge is not available, open the
existing plain water valve and note the amount
of water flowing. Open a carbonated water
valve until the carbonator pump turns on.
Check the plain water flow again. If the water
flow is greatly reduced, plan for a dedicated
plain water line from the back room to the
Variety valve.
C. Run new syrup lines from the back room to the
dispenser.
• If the existing syrup lines are underground and 2
extra lines are not available in the current tube
bundle, run a new tube bundle.
• If the existing syrup lines are in the ceiling, run 2
new lines beside the existing lines.
D. D. For carbonated water drink set up, check
access to carbonated water line or carbonator.
3. Remove the Existing Valve
Use safety glasses during the installation.
A. Unplug the power supply to the unit.
B. Depressurize the water and syrup BIB. Flush all
lines of all syrup and water.
C. Gain access to the back of the mounting plate.
For drop-in dispensers, remove the splash plate.
For ice-drink units, remove the splash plate and
if needed, remove the ice chute.

D. Remove the existing plain water valve and
mounting block from the dispenser. Remove 3
adjacent valves to provide more working space.
E. Remove the inlet water and syrup fittings from
the mounting plate. If the fittings are foamed in
place, remove the foam to access the fittings.
Push the 24 volt connector and wires to the
back of the mounting plate.
4. Install the Retrofit Mounting Plate
A. Apply the grease that is included in the tool kit to
the tip and the threads of the bolt and to the
sides and back of the punch before each use.
C. Hold the rear support die behind the mounting plate
so that the 4 holes on the die are aligned with the
mounting plate holes. Make sure the label on each
piece of the knockout tool is facing up.
D. Place the front barrel die against the mounting
plate aligning the cap screws with the mounting
plate holes. Tighten each of the 4 cap screws
with the included hex key.
B. Load the knockout punch (cutting part) into the front
barrel die. Make sure the bolt is backed out enough
to allow the points of the knockout punch to be fully
enclosed in the front barrel die so that the front
barrel die will lay flush against the mounting plate.
Part Number 020004001 4/122-11
To ensure the cap screws are properly
tightened, tighten each cap screw until its head
bottoms out on the face of the front punch
barrel, and tighten an additional 1/2 turn.
Recheck the tightness of each cap screw, and
retighten if necessary.
Make sure each of the 4 cap screws are securely
tightened prior to proceeding. If all 4 screws are not
tightened properly, the tool may not operate
correctly and damage to the tool may occur.
E. Use a socket wrench to turn the bolt clockwise
until the knockout punch completely breaks
through the mounting plate.
F. Remove the entire knockout tool and dispose of
the piece punched out of the mounting plate.

valves are in place, slowly pressurize the water
and syrup lines one at a time and make sure no
leaks occur.
SYSTEM PRESSURES
Incoming tap water - must be at a minimum dynamic
pressure of 40 psi and maximum static pressure of 60 psi.
The operating water pressure for the Variety Valve is 40-60
psig. If the incoming water pressure is not 40-60 psig,
adjust the water regulator. If a water regulator is not
installed, it is strongly recommended to install a water
regulator and, if necessary, a water booster system. The
operating syrup pressure for the Variety Valve is 60 psig
Water boosters are preset to turn on at 65 psi and off
at 85 psi.
D. Attach the 24 volt connector to the power supply.
Make sure the wires are placed inside the channel.
If the wires do not fit in the channel, trim the tab
enough to make the wires fit.
E. Brix the valve (see Valve Brix). Place the rear cover
on the valve. Make sure the ribbon cable is placed
behind the support on the rear valve cover.
