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.
2. Air and hydraulic hoses: use only electrically
conductive hoses.
3. Fluid hoses: use only electrically conductive fluid
hoses.
4. Air compressor or hydraulic power supply: follow
manufacturer’s recommendations.
5. Spray gun/dispensing valve: grounding is obtained
through connection to a properly grounded fluid
hose and pump.
6. Fluid supply container: according to your local
code.
7. Object being sprayed: according to your local
code.
8. 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 nonconductive surface, such as
paper or cardboard, which interrupts the grounding
continuity.
9. To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
spray gun/dispensing valve firmly to the side of a
grounded metal pail, then trigger the gun/valve.

SYSTEM ACCESSORIES
WARNING
A bleed-type master air valve (E) and a fluid drain
valve (M) are required in your system. These
accessories help reduce the risk of serious injury,
including fluid injection and splashing of fluid 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 pres-
sure 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 hoses (H) and fluid hoses (N) are prop-
erly sized and pressure-rated for your system. Use
only electrically conductive hoses. Fluid hoses must
have spring guards on both ends.
Mounting Accessories
WARNING
For Model 222940 Premier Pump, do not lift the
pump by the lift ring when the total weight exceeds
550 lb (250 kg).
Mount the pump (A) to suit the type of installation
planned. Fig. 3 on page 8 illustrates a ram-mounted
pump in a multi-gun header system. Pump dimensions
and the mounting hole layout are shown on pages 36
and 37.
If you are mounting the pump on a ram, refer to the
separate ram manual for installation and operation
instructions.
Air Line Accessories
Install the following accessories in the order shown in
Fig. 3, using adapters as necessary:
An air line lubricator (D) provides automatic air
motor lubrication.
A bleed-type master air valve (E) is required in
your system to relieve air trapped between it and
the air motor when the valve is closed (see the
WARNING above). Be sure the bleed valve is
easily accessible from the pump, and is located
downstream from the air regulator.
An air regulator (F) 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.
Apump runaway valve (C) 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 manifold (G) has a swivel air inlet. It
mounts to a ram, and has ports for connecting lines
to air accessories, such as the ram air regulator
(T).
An air line filter (J) removes harmful dirt and
moisture from the compressed air supply.
A second bleed-type air valve (K) 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 Fig. 3, using adapters as necessary:
Install a fluid shutoff valve (P) at each gun drop,
to isolate the gun and fluid accessories for servic-
ing.
Install a fluid drain valve (M) near the pump fluid
outlet, and at each gun station. The drain valves
are required in your system to relieve fluid pressure
in the displacement pump, hose and gun (see the
WARNING at left). Drain valves at the gun stations
may be mounted in the base of a fluid regulator
(L), using an adapter.
A fluid regulator (L) controls fluid pressure to the
gun/valve, and dampens pressure surges.
A gun or valve (S) dispenses the fluid. The gun
shown in Fig. 3 is a high pressure dispensing gun
for highly viscous fluids.
A gun swivel (R) allows freer gun movement.

Installation
(HYDRAULIC-POWERED PUMPS)
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawing.
Accessories are available from your Graco . If you
supply your own accessories, be sure they are ade-
quately sized and pressure-rated to meet the system’s
requirements.
The Typical Installation shown in Fig. 4 is only a guide
for selecting and installing system components and
accessories. Contact your Graco distributor for assis-
tance in designing a system to suit your particular
needs.
CAUTION
It is very important to keep the hydraulic supply
system clean at all times. Be sure that all hydraulic
fluid lines are absolutely clean. Blow out the lines
with air and flush thoroughly with solvent before
connecting to the hydraulic motor, to avoid introduc-
ing harmful contaminants into the motor. Plug the
hydraulic lines immediately when they are discon-
nected.
Do not exceed 37.8 liter/min (10 gpm) hydraulic oil
volume to the motor, to avoid pump stalling.
For optimum pump performance, keep the tempera-
ture of the hydraulic oil below 54C (130F)
