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 Accessories shown on page 8 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.
Grounding
Pump: use ground wire and clamp (supplied). Loosen
grounding lug locknut (W) and washer. Insert ground
wire end (Y) into lug (Z) slot and tighten locknut
securely. Connect ground clamp to a true earth ground.
Air and fluid hoses: use only electrically conductive
hoses. Check electrical resistance of hoses. If total
resistance to ground exceeds 29 megohms, replace
hose immediately.
Air compressor: follow manufacturer’s
recommendations.
Spray gun: ground through connection to a properly
grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray
gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
Mounting
Mount the pump to suit the type of installation planned.
The pump Dimensions and Mounting Hole Layout are
shown on page 26.
If the pump is immersed, be sure the pump intake is 1/2
in. (13 mm) off the bottom of the fluid container.
If the pump is mounted on the wall or on a stand,
connect a suction line to the pump’s 3/4 in. npt(f) fluid
inlet and place the other end of the line in the fluid
container.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes
to ignite or explode. Grounding provides an escape
wire for the electric current.

Accessories
8 308116V
Accessories
Install the following accessories in the order shown in
Operation, page 9, using adapters as necessary.
Air and Fluid Hoses
Be sure all air and fluid hoses are properly sized and
pressure--rated for your system. Use only conductive
air and fluid hoses. Fluid hoses must have spring
guards on both ends.
Connect a conductive fluid hose (L) to the pump’s fluid
outlet. See FIG. 1: Typical Installation on page 6.
Connect a fluid suction hose (N) to the pump’s 3/4
npt(f) fluid intake.
Use a conductive 1/2 in. I.D. (minimum) air hose (H) to
supply air to the pump.
Air Line
•Bleed-type master air valve (D): required in your
system to relieve air trapped between it and the air
motor when the valve is closed.
NOTE: Be sure the valve is easily accessible from
the pump and located downstream from the air
regulator.
•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.
•Air line lubricator (C): provides automatic air
motor lubrication.
•Pump air regulator (E): to control pump speed and
outlet pressure. Locate it close to the pump.
•Air line filter (F): removes harmful dirt and moisture
from compressed air supply.
•Second bleed-type air valve (G): isolates air line
accessories for servicing. Locate upstream from all
other air line accessories.
Fluid Line
•Fluid filter (K): filters particles from the fluid as it
leaves the pump.
•Fluid drain valve (J): required in your system, to
relieve fluid pressure in the hose and gun
•Gun (M): to dispense fluid.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid
contaminating your fluid with oil, flush the equipment
with a compatible solvent before using the equipment.
See Flush the Equipment.
If the pump is being used to supply a circulating
system, allow the solvent to circulate until the pump is
thoroughly flushed.
Trapped air can cause the pump to cycle
unexpectedly which could result in serious injury
from moving parts or splashing. A bleed--type
master air valve (D) is required in your system to
relieve trapped air between the valve and the pump
after the air is shut off.
Unrelieved fluid pressure in the system can result in a
skin injection injury. Triggering the gun to relieve
pressure may not be sufficient. A fluid drain valve (J)
is required in your system to help reduce the risk of
serious bodily injury including skin injection operating
or repairing the pump.

Operation
308116V 9
Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Engage the spray gun (M) trigger lock.
2. Close the bleed-type master air valve (D) to shut off
air supply to pump (A).
3. Disengage the spray gun trigger lock.
4. Hold a metal part of the spray gun (M) firmly to a
grounded metal pail. Trigger the gun to relieve
pressure.
5. Engage the spray gun trigger lock.
6. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Leave
drain valve(s) open until you are ready to spray
again.
7. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved:
a. VERY SLOWLY loosen the tip guard retaining
nut or the hose end coupling to relieve pressure
gradually.
b. Loosen the nut or the coupling completely.
c. Clear the obstruction in the hose or tip.
Flush the Equipment
• Flush before changing colors, before fluid can dry
in the equipment, at the end of the day, before
storing, and before repairing equipment.
• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
1. Perform Pressure Relief Procedure.
2. Remove spray tip and soak in solvent.
3. Hold a metal part of the spray gun (M) firmly to a
grounded metal pail.
4. Set pump (A) to lowest possible fluid pressure, and
start pump.
5. Trigger the spray gun until clean solvent dispenses.
6. Perform Pressure Relief Procedure.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
To avoid fire and explosion, always ground
equipment and waste container. To avoid static
sparking and injury from splashing, always flush at
the lowest possible pressure.

Operation
10 308116V
Packing Nut
Keep the packing nut/wet-cup (2) filled with Graco
Throat Seal Liquid (TSL™) or compatible solvent, to
help prolong the packing life. Adjust the packing nut
weekly so it is just tight enough to prevent leakage; do
not overtighten. Always follow the Pressure Relief
Procedure, page 9, before adjusting the packing nut.
Start and Adjust the Pump
1. See the Typical Installation on page 6. Be sure the
air regulator (E) and bleed--type master air valve (D)
are closed.
2. Connect a suction hose (N) to the pump fluid inlet.
3. Hold a metal part of the spray gun (M) firmly to the
side of a grounded metal pail and hold the trigger
open.
4. Open the pump bleed-type master air valve (D).
5. Slowly open the air regulator until the pump starts,
at about 40 psi (0.9 MPa, 2.8 bar).
6. Cycle the pump slowly until all the air is pushed out
and the pump and hoses are fully primed.
7. Release the spray gun trigger and engage the
trigger lock. The pump should stall against pressure
when the trigger is released.
8. Perform the Pressure Relief Procedure, page 9.
9. Install the spray tip in the gun.
10. With the pump and lines primed, and with adequate
air pressure and volume supplied, the pump will
start and stop as you open and close the gun. In a
circulating system, the pump will speed up or slow
down on demand, until the air supply is shut off.
NOTE: If the container is empty and air has been
pumped into the lines, refill the container and prime
the pump and the lines, or flush and leave it filled
with a compatible solvent. Eliminate all air from the
fluid system.
11. Use an adequately sized air regulator (E) to control
the pump speed and the fluid 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. Never operate the pump with the air
motor plates removes.
