Manitowoc FLOMATIC 464-GP Quick Manual

The Flomatic 464-GP valve provides superior
performance and exceptional durability for the life of
the valve. The GP features a broad operating range
from 2 to 4 oz./second to meet global dispensing
requirements. The GP is available in sanitary push
lever, push button, automatic fill lever, and portion
control models. With all models, mounting and ratio
control are the same.

All Flomatic valves are identified by a Model Number,
Serial Number, a manufacture month and year on the
underside of the flow control base. These numbers are a
helpful reference before beginning any valve service.

INSTALL OR REPLACE A VALVE

Flomatic created a kit (5007842) to replace both the
372-Q or 380-Q Flomatic mounting blocks. All
Flomatic mounting blocks are identical in appearance,
except for the part numbers shown on the front recess
of the block. The 380-Q has inlet ports sized at 0.380
in. and is compatible with Lancer or UF-1 fittings. The
372-Q inlet ports are sized at 0.372 in. and
accommodate a Cornelius SF-1 fitting. Select the
appropriate mounting option and install the mounting
block. Wet the inlet O-rings with water to ease
installation; do not use Vaseline®. Align the four bolt
holes and mount.

Be sure to relieve the system pressure before
removing or repairing the mounting block.

Remove the valve cover and align the valve stems with
the mounting block. Independent positive shut-offs and
the locking system prevent removal while the system is
pressurized. The valve cannot be removed unless the
shut-off valves are closed (arrows pointed across
service line).

The mounting hole pattern
typically has key slots to
secure the product supply
lines. If no key slots are
present, use the “S” clip
option.

Engage the valve and depress
the latch pin. Do not force or
you could bend the pin. If
you have difficulty, remount
the valve and try again. Be
sure the valve base is completely seated against the
block. Open the shut-off valves by turning 1/4 turn
(arrows pointed toward service line) to engage system
pressure.

SET FLOW RATE AND RATIO CONTROL

To simplify installation, the soda flow rate is optimized
for cold carb operation and is preset at the factory: 3.125
oz./second soda flow rate is standard for the 464-GP.
Should field conditions
require adjusting the
flow rate, clockwise
movement of the
adjustment screw
increases the flow rate
and vice versa.
Ceramic flow controls
can be adjusted from 2
oz./second to 4.0 oz./
second total flow rate
on the GP valve.

SET RATIO CONTROL

You will need a syrup separator, hex wrench (5/32
Allen), and brix cup. Place the Flomatic S-tube syrup

separator (part no.1089-00) over the syrup diffuser.
You need not remove the nozzle.

Most brix cups are calibrated for the standard 5:1 ratio.
Adjust the syrup flow by moving the adjusting screw
until the desired ratio is established.

INSTALL ADD-A-LEVER FOR “SODA ONLY”

The Flomatic Add-a-Lever is a two-piece assembly
which mounts on the pivot pin. Simply remove the
cover, partially withdraw the pivot pin to allow
mounting, reinsert the pin, replace the cover and you’re
done.

CONVERT TO PORTION CONTROL

Flomatic portion control electronics are contained in
the cover and can be factory or field installed. When
installing in the field, the 5031015 Conversion Kit for
the 464-GP makes it easy to add portion control.

The portion control module
is designed to simplify
installation. The board can
be programmed with the
first pour.

The “Stop/Fill” button
serves as a top-off button
and cancels any of the timed
portions if you need to abort the pour.

Each cup size must be programmed separately. Cup sizes
are preprogrammed at the factory: 1 second = small, 2
second = medium, 3 second = large, 4 second = x-large.

Set the flow rate first, brix the valve, and then set the
cup sizes to match your desired flow rate. Once the
valve is brixed, replace the valve cover and set the
times (cup sizes) from the front switch pad.

The switch pad has a hidden “program” switch that must
be held down to keep the module in program mode.
Setting the times or programming is a two-handed
operation; push and hold the program switch with one
finger while dispensing the cup size you wish to program
with another. Once the drink is full, simply release the cup
size button to end the pour cycle and then let go of the
program switch. Repeat the process for each cup size.

The module will remember one top-off cycle
automatically if the foam height requires it to complete
the pour. T o program a top-off cycle, begin programming
as described above. Once the foam crests the top of the
cup, PAUSE by removing your finger from the cup size
button. Do not release the program button. Pause long
enough for the foam to settle, and then continue the pour
with your finger on the same cup size button until the
cup is full. The module will remember the sequence
“pour - pause - pour” as it was executed.

If you program the top-off feature, be sure to train the
operators so they do not pull a drink before the cycle is
complete. The portion control module will finish the
pour whether a cup is there or not.

AUTOMATIC FILL VALVE

The 464-GP Automatic
Fill valve can be used to
dispense both carbonated
and noncarbonated
products. The valve is
factory set for carbonated
products where a delayed
top-off is standard, and
the wire-lead plug should
be attached to pins 1 and 2 (those furthest to the left). If
your installation uses noncarbonated products requiring

Valve should seat securely

Shut-off closed
Hidden Program Switch

no top-off, you will need to adjust the position of the lever
wire-lead plug on the electronics. For noncarbonated
products, the wire-lead plug should be attached to pins 2
and 3 (those furthest to the right), as shown in the photo.

The Automatic Fill valve requires no sensitivity
adjustments. The valve automatically delays top-off if
more foam is present after the initial pour, and performs
a top-off more quickly if less foam is present.

CLEANING

Under normal operating
conditions, periodic
cleaning is minimal but
absolutely necessary.
Remove the nozzle
assembly as shown,
soak it in warm water,
rinse and reinstall. Brush
the lever slot with warm
water to prevent syrup
build-up and sticking.
Wipe cover and panel
with a clean cloth and
you are finished.
Nothing more needs to
be done unless you
experience a problem.

Regular servicing and
cleaning of the complete beverage system is advised to
maintain proper functioning of the equipment. Be sure to
follow instructions provided by the manufacturer.

If refurbishing a piece of equipment, remove the
solenoid from the valve. Once removed, the entire
valve can be submerged in warm water for cleaning.

TROUBLESHOOTING

Occasionally, a valve will not perform as desired. Here
are some helpful tips for troubleshooting:

RATIO: Look for foreign matter in the adjustment
screws, flow controls or pallet seats. If a system is not
flushed completely at start-up, foreign particles may be
introduced into the system. Reset the flow rate and
readjust the syrup ratio.

BUZZING: Do not lubricate the plungers. If
contaminated, simply wash with hot water, dry and
reinstall.

LEAKS: Check for damaged or improperly fitted O­rings. The slightest piece of hair, dust, etc., on the
sealing surface may contribute to a leak. When in
doubt, replace an O-ring. Be sure you have the correct
O-ring and fitting combination for the respective
mounting plate.
