Installation
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawing.
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 5 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 on page 5.
WARNING
A bleed--type master air valve (D) and a fluid drain
valve (J) are required in your system. These accessories help reduce the risk of serious bodily 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 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.
Connect a fluid suction hose (N) to the pump’s 3/4
npt(f) 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:
An air line lubricator (C) provides automatic air
motor lubrication.
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 downstream from the air
regulator.
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.
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.
An air line filter (F) removes harmful dirt and moisture from the compressed air supply.
The fluid drain valve assists in relieving fluid 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. Refer to the Dimensions and Mounting
Hole Layout page 24.
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 fluid
outlet.
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 necessary:
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 pointing down,
but so the handle points up when opened.
A fluid filter (K) filters harmful particles from the fluid.
A spray gun (M) dispenses the fluid. The gun shown
in the Typical Installation is an airless spray gun.

Operation/Maintenance
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying accidentally. T o reduce the risk of an injury from accidental spray from the gun, splashing fluid, or
moving parts, follow the Pressure Relief Proce-
dure whenever you:
D are instructed to relieve the pressure,
D stop spraying,
D check or service any of the system equipment,
D or install or clean the spray tip.
1. Lock the spray gun safety latch.
2. Shut off the air supply to the pump.
3. Close the bleed-type master air valve (required in
your system).
4. Unlock the gun safety latch.
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
6. Lock the gun safety latch.
7. Open the drain valve (required in your system),
having a container ready to catch the drainage.
8. Leave the drain valve open until you are ready to
spray again.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
tip guard retaining ring or hose end coupling and
relieve pressure gradually, then loosen completely.
Now clear the tip or hose.
WARNING
Moving parts can pinch or amputate your fingers or
other body parts. When air is supplied to the motor,
the air motor piston (located behind the air motor
plates) moves. See Fig. 3. Therefore, never operate the pump with the air motor plates removed.
Flush the Pump Before First Use
The pump is tested with lightweight motor oil, which is
left in to protect the pump parts. If the fluid you are
using may be contaminated by the oil, flush it out with
a compatible solvent before using the pump. If the
pump is being used to supply a circulating system,
allow the solvent to circulate until the pump is thoroughly flushed.
WARNING
For your safety, read the warning section, Fire or
Explosion Hazard, on page 4 before flushing,
and follow all the recommendations given there.
