Connect the Fluid Lines
Connect a grounded fluid line (F) from the pump to the
fluid inlet adapter (19) of the dispensing valve. You
should install a fluid pressure regulator (P) to control
fluid pressure to the dispensing valve. A regulator
enables you to control fluid pressure more accurately
than by regulating air pressure to the pump.
Install a fluid filter (R) to remove particles and sedi-
ment which may clog the nozzle.
In a circulating system, remove the plug (4) from the
circulation port (X). Connect a return line (M) from the
circulating port to the back pressure valve. The back
pressure valve ensures regulated pressure to all
dispensing valves in the system.
Installation
System Accessories
Two accessories are required in your system: a
bleed-type master air valve (A) and a fluid drain
valve (D). These accessories help reduce the risk
of serious injury including fluid injection, splashing
in the eyes or on the skin, and injury from moving
parts if you are adjusting or repairing the pump.
The bleed-type master air valve is required only
with air-powered pumps. It relieves air trapped
between this valve and the pump after the air
regulator is shut off. Trapped air can cause the
pump to cycle unexpectedly. Locate the valve close
to the pump.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and dispens-
ing valve; triggering the valve to relieve pressure
may not be sufficient.
