Fig. 1
3. Air and fluid hoses: use only electrically conductive
hoses.
4. Air compressor: follow manufacturer’s recommendations and local codes.
5. Spray gun: ground through connection to a properly grounded fluid hose and pump.
6. Fluid supply container: follow your local code.
0720
Although water generally provides a natural electrical
ground, the following equipment must be grounded if
the cleaning chemicals are volatile.
1. When cleaning in enclosed areas, such as storage
tanks, locate the pump and air compressor outside
the area and well away from it. Provide adequate
ventilation. If the area you are cleaning has stored
flammable materials, take appropriate precautions
to avoid static sparking. Consult your local codes.
2. Pump: use the ground wire and clamp (supplied).
See Fig. 1. Loosen the grounding lug locknut (W)
and washer (X). Insert one end of the 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.
7. Object being sprayed: follow your local code.
8. 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.
9. To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the spray
gun firmly to the side of a grounded metal pail,
then trigger the gun.
Mounting the Pump
Mount the pump (A) to suit the type of installation
planned. The pump dimensions and mounting hole
layout are shown on page 23.

System Accessories
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 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 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 a 1/2 in. (13 mm)
ID (minimum) air hose (H). Connect a fluid hose (K) to
the pump’s fluid outlet. Fluid hoses must have spring
guards on both ends. Connect a fluid suction hose (M)
to the pump’s 3/4 npt(f) fluid intake.
Air Line Accessories
Install the following accessories in the order shown in
Fig. 2, using adapters as necessary:
An air line lubricator (C) provides automatic air
motor lubrication. For manual lubrication, see page
10.
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 down-
stream from the air regulator. Order Part No.
113333.
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.
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 Fig. 2, 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. Order Part No. 235992.
A Hydra-Clean spray gun (L) dispenses the
cleaning fluid.

Operation
Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying 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:
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 gun trigger safety.
2. Close the bleed-type master air valve (D, required
in your system).
3. Unlock the gun trigger safety.
4. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
Packing Nut/Wet-Cup
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
Keep the packing nut/wet-cup (15) 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. See Fig. 3. Relieve the pressure before
adjusting the packing nut.
Flush the Pump Before First Use
The pump is tested with lightweight oil, which is left in
to protect the pump parts. To prevent contamination of
the cleaning solution, flush the pump with a compatible
solvent before using it. See Flushing on page 10.
5. Lock the gun trigger safety.
6. Open the drain valve (J, required in your system),
having a container ready to catch the drainage.
7. 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.
Mixing the Cleaning Solution
If you are adding a cleaning chemical to the water, mix
it thoroughly with a few gallons of water in a separate
container before adding to the drum. Be sure all particles are well dissolved. Read and follow the chemical
manufacturer’s recommendations on mixing and
application of the solution.
Fill the drum with water and the desired, premixed
cleaning solution.
