WARNING

Setup
6 306817N
Setup
Grounding
Although water generally provides a natural electrical
ground, the following equipment must be grounded if the
cleaning chemical 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. Consul your
local codes.
2. 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 mm2(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.
FIG. 1
3. Air and fluid hoses: use only electrically
conductive hoses.
4. Air compressor: follow manufacturer’s
recommendations.
5. Spray gun: ground through connection to a
properly grounded fluid hose and pump.
6. Fluid supply container: follow your local code.
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.
General Information
The typical setup shown in FIG. 2 is only a guide to
selecting and installing required and optional
components. For assistance in designing a system to
suit your needs, contact your Graco distributor. Refer to
FIG. 2 for callouts in parentheses.
Before operating the pump, ground the system as
explained below. Also read the section FIREAND
EXPLOSION HAZARD on page 5.

Setup
306817N 7
Connect Hoses and Mount Pump
1. Using Loctite Pipe Sealant, screw the hose stud
(10) of the suction hose into the pump’s intake
housing. See FIG. 2. Remove one of the screws
from the pump base opposite the outlet, and
assemble the hanging bracket (19) to the pump with
the provided screw (9)—use the lockwasher that
was on the replaced screw.
2. Using Loctite®Pipe Sealant, screw the accumulator
(7) inlet adapter into the pump outlet. Connect the
fluid hose to the accumulator, the nozzle to the
spray valve, and the air line lubricator (3) to the
pump air inlet. Hang the pump on your cleaning
solution drum.
NOTE: The filter on the suction hose should be
about 1/2 in. (12.7 mm) off the bottom of the drum. If
the hose is too long, cut it off as necessary.
3. Close the air ball valve (24), then connect your 1/2
ID (min) air supply hose to the 1/2 nptm(f) inlet
union (15)—do not use thread sealer. Install an
accessory air filter and water separator to remove
excessive moisture that could cause air motor icing.
Pour high quality SAE 10 into the lubricator until oil
reaches the level mark on the sight glass.
NOTICE
Oils containing phosphate ester or chlorinated hydro-
carbons are not compatible with the plastic bowl of
the lubricator—be sure that oil used to lubricate the
compressor is free of these additives.

Operation

Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Lock the Hydra-Clean®gun trigger safety.
2. Close the pump air regulator.
3. Close the red handled bleed-type master air valve
(required in your system)
4. Unlock the gun trigger safety and trigger the gun to
relieve pressure.
5. Lock the gun trigger safety.
6. Open the pump drain valve, 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 dispensing valve, extension, or
grease fitting coupler is clogged, or that pressure has
not been fully relieved after following the steps above,
VERY SLOWLY loosen the coupler or hose end
coupling and relieve pressure gradually, then loosen
completely, now clear the clog.
Before Using
Prepare cleaning solution as instructed, observing all
safety precautions. Pre-mix powered cleaners in a
separate bucket of hot water before adding to water in
the supply drum.
See FIG. 2. Open the main air supply valve, hold the
spray valve open and slowly open the air petcock until
the pump is running slowly. After solution is coming from
the spray nozzle, open the ball valve (24) all the way
and adjust the air line lubricator (3) to deliver about one
drop per minute. Refer to the separate lubricator
instruction manual.
Release the spray valve trigger and let the pump run.
The pump will charge the accumulator with liquid
pressure, then stall.
NOTE: Protect surfaces that might be damaged by the
cleaning solution and rinse before the solution dries on
both surfaces. You can clean stubborn dirt off better with
a stronger, heated solution.
WARNING
To avoid serious injury, including fluid injection and
splashing in the eyes or on the skin, never point the
gun at yourself or anyone else.
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 nozzles.
WARNING
Take care not to get spray containing cleaning
chemicals into your eyes, ears, or nose. If any spray
does get on your skin or in your eyes, flush
immediately and thoroughly with water. Seek
immediate medical attention.

Operation
306817N 9
Useful Hints
Hold the spray nozzle about 2 feet (0.6 m) from the
surface and completely mist-wet the object you are
cleaning. Let it soak briefly, then use the spray to
“chisel” the dirt off—keep the nozzle about 6 in. (152.4
mm) from, and at an angle to the surface. If some dirt
remains, wet the surface again. Let the object soak a
little longer, then hold the nozzle as close as possible
and spray to blast the dirt off.
FIG. 2
After all the dirt is cleaned off, rinse all the solution off
with clear, cold water. When you are through cleaning,
close the air petcock and follow the Pressure Relief
Procedure, page 8.
Shutdown and Care of Unit
When shutting down for the day or weekend, shut off the
main air supply and relieve the pressure. Rinse all
solution off the equipment with clear, cold water, Shut
off the water supply valve and relieve the water
pressure.
Check the air line lubricator (3) often and keep it filled
with oil. Also check the pump packing nut regularly and
keep it just tight enough to stop leakage, but no tighter.
Use a 1/4 in. diameter rod to tighten.
WARNING
To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the
Pressure Relief Procedure, page 8.
