Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 4.
To reduce the risk of static sparking, ground the pump.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Be
sure to ground all of this dispensing equipment.
1. Pump: loosen the grounding lug locknut (W) and
washer (X). Insert one end of a 1.5 mm2 (12 ga)
minimum ground wire (Y) into the slot in lug (Z)
and tighten the locknut securely. See Fig. 1. Connect the other end of the ground wire to a true
earth ground. Order Part No. 237569 Ground Wire
and Clamp.
4. Spray gun: grounding is obtained through connection to a properly grounded fluid hose and pump.
5. Object being sprayed: according to your local
code.
6. Fluid supply container: according to your local
code.
7. All solvent pails used when flushing, according to
your local code. Use only metal pails, which are
conductive, placed on a grounded surface. Do not
place the pail on a non-conductive surface, such
as paper or cardboard, which interrupts the
grounding continuity.
8. To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
spray gun firmly to the side of a grounded metal
pail, then trigger the spray gun.

Y
2. Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft (150 m) combined
hose length to ensure grounding continuity.
3. Air compressor: follow manufacturer’s recommendation.

Installation
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
Parts Drawing.
NOTE: Contact you Graco distributor for available
Graco accessories. If you supply your own accessories, be sure they are adequately sized and pressurerated to meet the system’s requirements.
The Typical Installation shown on page 6 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 6.
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 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.
Connect a electrically conductive fluid hose (L) to the
fluid filter (K), if used, or directly to the pump’s fluid
outlet.
Use a electrically conductive 1/2 in. ID (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.
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 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. The pump dimensions and mounting hole
layout are shown on page 26.
The pump is supplied with a bung adapter. To mount
the pump, loosen the bung adapter screw and slide the
adapter off the pump. Screw the bung adapter securely into the bung hole on the cover of the supply drum.
Carefully lower the pump through the bung adapter
and into the drum until it rests on the bottom, then pull
it back up 1/2 in. (13 mm). Tighten the bung adapter
screw to hold the pump in this position. Open the
drum’s vent plug to prevent a vacuum from forming in
the drum.
Air and Fluid Hoses
Be sure all air and fluid hoses are properly sized and
pressure-rated for your system. Use only electrically
conductive air and fluid hoses. Fluid hoses must have
spring guards on both ends.
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.
A second bleed-type master air valve (G) iso-
lates 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.

Pressure Relief Procedure
Operation
WARNING
WARNING
SKIN INJECTION HAZARD
Fluid under high pressure can be injected through the skin and cause
serious injury. To reduce the risk of an
injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
or install or clean the spray tips.
1. Lock the spray gun trigger safety.
2. Shut off the air to the pump.
3. Close the bleed-type master air valve (required in
your system).
4. Unlock the gun trigger safety.
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
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. 2. Therefore, never operate the pump with the air motor plates removed.
Flush the Pump Before Using
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
FIRE AND EXPLOSION HAZARD
For your safety, read the section FIRE
AND EXPLOSION HAZARD on page 4
before flushing and follow all the recommendations given there.
6. Lock the spray gun trigger safety.
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 nut or hose end coupling and relieve
pressure gradually, then loosen completely. Now clear
the tip or hose.
