Installation for
Model G56
Flow Reversal Valve
ASSEMBLY DIAGRAM
MOUNTING
• Pump must be located within 10 ft. (1.83 m) above or below
the keg or cask.
• Pump ports must be facing down to maximize pump
performance.
•Mounting grommets are part of pump assembly and add
stability.
• Fasten pump securely to wall or rack.
• If using a FOB device, mount it slightly above and directly
after the discharge of the pump. Caution: If a FOB is not
used, the pump will continue to cycle after the keg has run dry.
APPLICATION INFORMATION
Flojet’s G56 Flow Reversal Valve (FRV) is designed as an add-on
accessory for the G56 Beer Pump to allow beer line cleaners
to run cleaning solution through a Flojet G56 pump driven beer
system in both directions. Running cleaning solution through
draught beer systems in alternating directions from the faucet
to the tapping device (and vice versa) has been found
to enhance cleaning efficiency. Further, a multiple beer faucet
system utilizing G56 beer pumps with Flow Reversal Valves
allows for multiple lines to be cleaned at one time. This can
be done by connecting keg taps with double flushers
and connecting faucets with cleaning jumpers (see Line
Cleaning Diagram).
TYPICAL INSTALLATION
ASSEMBLY TO G56 PUMP
1. Slide port clips back against base of pump.
2. Insure that both O-rings of the FRV are adequately
lubricated.
3. Slide FRV ports into pump and secure with clips (see
Assembly Drawing).
4. Attach inlet tubing from keg to the left side port fitting and
secure with Oetiker Clamp (clamps not provided).
5. Attach discharge tubing to the right side port fitting and
secure with Oetiker Clamp.
6. Install air inlet and exhaust ports to pump.

Installation Instructions (form #81000-303). For normal
dispensing, if a Flow Reversal Valve is added to the pump, the
set-up would be as shown in the Typical Installation Drawing.
Note that the valve is in the “Dispense Position” (see Valve
Positions Drawing).
For cleaning one line from the faucet to the keg tap:
1. Turn the valve to the “Reverse Flow” position.
2. Attach a cleaning jumper to the faucet.
3. Set FOB to bypass mode.
4. Pump the cleaning solution from the faucet to the keg tap.
5. Be sure to rinse system with cold, clean rinse water.
6. After cleaning and rinsing system, return all valves to
normal operating (Dispense) positions.
For cleaning multiple lines:
1. Attach a cleaning jumper to the first faucet.
2. Turn the valve to the “Reverse Flow” position.
3. Connect the keg tap from the first line to the keg tap of
the second line with a double flusher.
4. Leave the valve on the second pump in the "Dispense
Position.”
5. Connect the second faucet to the third faucet with a
cleaning jumper.
6. Repeat steps 2 through 5.
7. Set all FOBs to bypass mode.
8. Circulate cleaning solution through system.
9. Be sure to rinse system with cold, clean rinse water.
10. After cleaning and rinsing system, return all valves to
normal operating (Dispense) positions.
CAUTION: Do not close the system while running the
cleaning pumps. Excessive pressure build-up could
damage pumps.
