System Accessories
To ensure maximum pump performance, be sure that all
accessories used are properly sized to meet your
system’s requirements. See Accessories, page 24.
Air Line Accessories
Install the following accessories in the order shown in
the Gun Fluid Manifold, page 9, using adapters as
necessary:
An air line lubricator (AB) provides automatic air
motor lubrication.
A bleed-type master air valve (AD) is required in your
system to relieve air trapped between it and the air
motor when the valve is closed (see the WARNING on
left). Be sure the bleed valve is easily accessible from
the pump, and is located downstream from the air
regulator.
An air line filter (AC) to remove harmful dirt and
moisture from the compressed air supply.
A second bleed-type air valve (AD) isolates the air line
accessories for servicing. Locate upstream from all
other air line accessories.
Fluid Line Accessories
A fluid drain valve (BA) is required in your system to
relieve fluid pressure in the hose and gun (see the
WARNING on left). Install the drain valve so that it
points down and the handle points up when the valve is
opened.
A bleed-type master air valve (D) and a fluid drain
valve (E) are required in your system, to help reduce
the risk of serious injury, including splashing fluid in
the eyes or on the skin, and injury from moving parts
when you are adjusting or repairing the pump.
• The bleed-type master air valve (D) relives air
trapped between this valve and the pump after the
pump is shut off. Trapped air can cause the pump
to cycle unexpectedly and result in serious injury,
including amputation. Install the valve close to the
pump.
• The fluid drain valve (E) helps relieve pressure in
the displacement pump, hose, and dispensing
valve when shutting off the pump. Actuating the
dispensing valve to relieve pressure may not be
sufficient, especially if there is a clog in the hose or
the spray gun or dispensing valve.
