Installation
General Information
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawings.
NOTE: If you supply your own accessories, be sure
they are adequately sized and pressure–rated to meet
the system’s requirements.
Fig. 2 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
WARNING
Two accessories are required in your system: a
bleed–type master air valve (J) and a fluid drain
valve (N). 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.
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.
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 a braided
stainless steel cover (or have spring guards on both
ends).
Mounting Accessories
Mount the pump (A) to suit the type of installation
planned. The pump dimensions and mounting hole
layouts are shown on pages 28 and 29.
The Typical Installation on page 7 shows the pump
(A) mounted on a pneumatic elevator cart (B). The
pump may also be mounted on a 19 liter (5 gal.) pail
ram. In either case, it is used with a wiper plate (C).
Refer to the separate manuals for the cart, ram, and
wiper plate for further information.
Kits 223881 and 224829 are available to mount the
pump on a 200 liter (55 gallon) ram. Refer to the
separate manuals included with the kits for further
information.
Air Line Accessories
Install the following accessories as shown in Fig. 2,
using adapters as necessary:
D A pump runaway valve (G) 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 (H) provides automatic air
motor lubrication.
D A bleed-type master air valve (J) 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 (K) 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 (L) removes harmful dirt and
moisture from the compressed air supply.
D A second bleed-type air valve (M) isolates the air
line accessories for servicing. Locate upstream
from all other air line accessories.
D An air line quick disconnect coupler (F) is
required for pumps mounted on the pneumatic
elevator cart. The female coupler attaches to the
end of the air hose (D), and the male coupler
screws into the air manifold (E). See the separate
cart manual for further information.
308200 5
Installation
Fluid Line Accessories
Install the following accessories in the positions shown
in Fig. 2, using adapters as necessary:
D A fluid drain valve (N) is required in your system
to relieve fluid pressure in the hose and gun (see
the WARNING at left). Screw the drain valve into
the open branch of a tee mounted in the fluid line.
Install the drain valve pointing down, but so the
handle points up when opened.
D A fluid regulator (P) controls fluid pressure to the
gun/valve, and dampens pressure surges.
D A gun or valve (S) dispenses the fluid. The gun
shown in the Typical Installation is a dispensing gun
for highly viscous fluids.
D A gun swivel (T) allows freer gun movement.

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.
1. Pump: use a ground wire and clamp. See Fig. 1.
Loosen the grounding lug locknut (W) and washer
(X). Insert one end of a 1.5 mm@ (12 ga) minimum
ground wire (Y) into the slot in lug (Z) and tighten
the locknut securely. Connect the other end of the
wire to a true earth ground. Order Part No. 237569
Ground Wire and Clamp.
6. Object being sprayed: follow your local code.
7. All solvent pails used when flushing: follow your
local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not
place the pail on a nonconductive 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
gun/valve firmly to the side of a grounded metal
pail, then trigger the gun/valve.

Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or dispensing accidentally. 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:
D are instructed to relieve the pressure,
D stop spraying/dispensing,
D check or service any of the system equipment,
D or install or clean the spray tip/nozzle.
1. Lock the gun/valve trigger safety.
2. Close the pump’s bleed-type air valve (required in
your system).
Packing Nut/Wet-Cup
Before starting, fill the packing nut (2) 1/3 full with
Graco Throat Seal Liquid (TSL) or compatible solvent.
See Fig. 3. Adjust the packing nut weekly so it is just
snug; do not overtighten.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
Air Motor Plate
3. Shut off the master air bleed valve (required in
your system).
4. Unlock the gun/valve trigger safety.
5. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail, and trigger the gun/valve
to relieve pressure.
6. Lock the gun/valve 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/dispense again.
If you suspect that the spray tip/nozzle 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/nozzle or hose.

Operation
Flush the Pump Before First Use
The pump is tested with lightweight 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. See Flushing on page 10.
Starting and Adjusting the Pump
WARNING
MOVING PARTS HAZARD
See Fig. 3. The priming piston (23) and
the air motor piston (located behind the
air motor plates) move during operation.
Keep hands and fingers away from the priming
piston (23) during operation and whenever the
pump is charged with air. The priming piston extends beyond the intake cylinder (20) to pull material into the pump and can amputate a hand or finger
caught between it and the intake cylinder. Follow
the Pressure Relief Procedure on page 8,
before checking, clearing, or cleaning the priming
piston to prevent the pump from starting accidentally.
NOTE: When changing fluid containers with the hose
and gun already primed, be sure to open the bleeder
valve (33), to assist in priming the pump and venting
air before it enters the hose. Close the valve when all
air has been eliminated.
WARNING
SKIN INJECTION HAZARD
To reduce the risk of fluid injection, do not use
your hand or fingers to cover the bleed hole on the
underside of the bleeder valve body when priming
the pump. Use a crescent wrench to open and
close the bleeder plug. Keep your hands away from
the bleed hole.
With the pump and lines primed, and with adequate air
pressure and volume supplied, the pump will start and
stop as the spray gun/dispensing valve is opened and
closed.
Use the air regulator (K) to control the pump speed and
the fluid pressure. Always use the lowest air pressure
necessary to get the desired results. Higher pressures
cause premature tip/nozzle and pump wear.
Never operate the pump with the air motor plates
removed.
See the Installation on page 7. If you are using a
pneumatic elevator cart or 19 liter (5 gallon) ram with
the pump, refer to the separate instructions for those
components for set-up and operation instructions.
Lower the pump into a fluid container. Be sure the air
regulator (K) and bleed-type master air valve (J) are
closed. Then open the bleed valve (J). Hold a metal
part of the spray gun/dispensing valve (S) firmly to the
side of a grounded metal pail and hold the trigger
open. Now slowly open the air regulator until the pump
starts.
Cycle the pump slowly until all the air is pushed out
and the pump and hoses are fully primed. Release the
spray gun/dispensing valve trigger and engage the
safety latch. The pump should stall against pressure
when the trigger is released.
If the pump fails to prime properly, open the bleeder
valve (33) slightly. See Fig. 7 on page 16. Use the
bleeder hole (on the underside of the valve housing) as
a priming valve until the fluid appears at the hole.
Close the bleeder valve.
WARNING
To reduce the risk of overpressurizing the system,
which could result in component rupture and cause
serious injury, NEVER exceed the specified maximum incoming air pressure to the pump (see the
Technical Data on pages 24–27).
CAUTION
Do not allow the pump to run dry. It will quickly
accelerate to a high speed, causing damage. A
pump runaway valve (G), which shuts off the air
supply to the pump if the pump accelerates beyond
the pre-set speed, is available. See the Typical
Installation in Fig. 2. If your pump accelerates
quickly, or is running too fast, stop it immediately and
check the fluid supply. If the supply container is
empty and air has been pumped into the lines, refill
the container and prime the pump and the lines with
fluid, or flush and leave it filled with a compatible
solvent. Be sure to eliminate all air from the fluid
system.
