Installation
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawing.
Contact your Graco distributor for available accesso-
ries. If you supply your own accessories, be sure they
are adequately sized and pressure–rated to meet the
system’s requirements.
The Typical Installation shown on page 7 is only a
guide for selecting and installing system components
and accessories. Contact your Graco distributor for
assistance in designing a system to suit your particular
needs.
System Accessories
Refer to the Typical Installation drawing on page 7.
WARNING
Two accessories are required in your system: a
bleed-type master air valve (D) and a fluid drain
valve (J). These accessories help reduce the risk
of serious injury including 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 relieves air trapped
between this valve and the pump after the air 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 pressure in
the displacement pump, hose, and gun. Triggering
the gun to relieve pressure may not be sufficient.
Mounting Accessories
Mount the pump (A) to suit the type of installation
planned. The pump dimensions and mounting hole
layout are shown on page 22.
Air and Fluid Hoses
Be sure all air and fluid hoses are properly sized and
pressure–rated for your system. Use only grounded air
and fluid hoses. Fluid hoses must have spring guards
on both ends.
Connect a grounded fluid hose (L) to the pump’s 3/8
npt(f) fluid outlet. Use of a short whip hose between
the main fluid hose (L) and the gun (M) allows freer
gun movement.
Connect a fluid suction hose (N) to the pump’s 3/4
npt(m) fluid intake.
Use a grounded 1/2 in. I.D. (minimum) air hose (H) to
supply air to the pump.
Air Line Accessories
Install the following accessories in the order shown in
the Typical Installation, using adapters as necessary:
D A pump runaway valve (B) senses when the
pump is running too fast and automatically shuts off
the air to the motor. A pump which runs too fast can
be seriously damaged. Install closest to the pump
air inlet.
D An air line lubricator (C) provides automatic air
motor lubrication.
D A bleed–type master air valve (D) is required in
your system to relieve air trapped between it and
the air motor when the valve is closed (see the
WARNING at left). Be sure the bleed valve is easily
accessible from the pump, and is located down-
stream from the air regulator.
D An air regulator (E) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. Locate the regulator close to the pump, but
upstream from the bleed–type master air valve.
D An air line filter (F) removes harmful dirt and
moisture from the compressed air supply.
D A second bleed–type air valve (G) isolates the air
line accessories for servicing. Locate upstream
from all other air line accessories.
Fluid Line Accessories
Install the following accessories in the positions shown
in the Typical Installation, using adapters as neces-
sary:
D A fluid drain valve (J) is required in your system
to relieve fluid pressure in the hose and gun (see
the WARNING at left). Install the drain valve point-
ing down, but so the handle points up when
opened.
D A fluid filter (K) filters harmful particles from the
fluid.
D A spray gun (M) dispenses the fluid. The gun
shown in the Typical Installation is an airless spray
gun.
