NOTE: Always use Genuine Graco Parts and Acces-  
sories, available from your Graco distributor. Refer to  
the Product Data Sheet for your pump, Form No.  
305791. If you supply your own accessories, be sure  
they are adequately sized and pressure rated for your  
system.

Fig. 1  
2. Air and fluid hoses: use only electrically conductive  
hoses.  
NOTE: 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.  
3. Heaters, if used: refer to Viscon HP Heater manu-  
al, 309524.  
4. Air compressor: follow manufacturer’s recommen-  
dations.  
Grounding  
5. Spray gun: ground through connection to a prop-  
erly grounded fluid hose and pump.  
WARNING  
6. Fluid supply container: follow your local code.  
7. Object being sprayed: follow your local code.  
FIRE AND EXPLOSION HAZARD  
Before operating the pump, ground the  
system as explained below. Also read  
the section FIRE OR EXPLOSION HAZ-  
ARD on page 4.  
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 continu-  
ity.  
1. Pump: use a ground wire and clamp (supplied).  
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 (45) into the slot in lug  
(Z) and tighten the locknut securely. Connect the  
other end of the wire to a true earth ground.  
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.

Installation  
Supplied Components  
System Accessories  
Refer to Fig. 2 for a typical installation of an airless  
system.  
Air and Fluid Hoses  
Be sure all air hoses (A) and fluid hoses (G) are prop-  
erly sized and pressure-rated for your system. Use  
only electrically conductive hoses.  
WARNING  
A red-handled bleed-type master air valve (14) and  
a fluid drain valve (7) are supplied 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.  
1. Connect one end of the fluid line (G) to the filter  
outlet swivel. Connect a fluid hose to each gun (H).  
Install a fluid shutoff valve (J) at each gun drop.  
Do not install the spray tip in the gun yet.  
The red-handled bleed-type master air valve re-  
lieves 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.  
2. Close the red-handled bleed valve (14) and air  
regulator (8). Connect the air hose (A) to the  
swivel inlet of the air manifold (15).  
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 Line Accessories  
D The red-handled bleed-type master air valve  
(14) 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.  
1. Install an air line filter (B) in the main air line, to  
remove harmful dirt and moisture from the com-  
pressed air supply.  
D The air regulator (8) 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 red-handled bleed-type master  
air valve (14).  
2. Install a second bleed valve (C) in the main air  
line, to isolate the accessories for servicing.  
3. Install a drain valve (D) at the bottom of each air  
D The air manifold (15) has a swivel air inlet. It  
mounts to the cart, and provides ports for connect-  
ing lines to air-powered accessories.  
line drop, to drain off moisture.  
D The fluid filter (4) includes a 60 mesh (250 mi-  
cron) stainless steel element to filter particles from  
the fluid as it leaves the pump.  
4. To provide automatic lubrication of the air motor,  
install an air line lubricator (E) downstream from  
the red-handled bleed-type master air valve (14).  
D The fluid drain valve (7) is required in your sys-  
tem to relieve fluid pressure in the hose and gun  
(see the WARNING above).  
5. Install a pump runaway valve (F). The runaway  
valve will automatically shut off the air to the pump  
if the pump starts running too fast. A pump that  
runs too fast can be seriously damaged.  
D The suction hose (24) and tube (25) allow the  
pump to draw fluid from a 200 liter (55 gallon)  
drum.

Operation/Maintenance  
Pressure Relief Procedure  
Packing Nut/Wet-Cup  
Before starting, fill the packing nut (U) 1/3 full with  
Graco Throat Seal Liquid (TSL) or compatible solvent.  
See Fig. 7.  
WARNING  
SKIN INJECTION HAZARD  
The system pressure must be manually  
relieved to prevent the system from  
WARNING  
To reduce the risk of serious injury whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure at left.  
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:  
The packing nut is torqued at the factory and is ready  
for operation. If it becomes loose and there is leaking  
from the throat packings, relieve pressure, then tighten  
the nut as specified in your separate pump manual. Do  
this whenever necessary. Do not overtighten the  
packing nut.  
D are instructed to relieve the pressure,  
D stop spraying,  
D check or service any of the system equipment,  
D or install or clean the spray tips.  
1. Lock the gun trigger safety.  
Flush the Pump Before First Use  
2. Shut off the air supply to the pump.  
Pumps are tested with lightweight oil which is left in to  
protect the pump parts. To prevent contamination of  
the fluid, flush the pump with a compatible solvent  
before using it.  
3. Close the bleed-type master air valve (required in  
your system).  
4. Unlock the gun trigger safety.  
5. Hold a metal part of the gun firmly to the side of a  
grounded metal pail, and trigger the gun to relieve  
pressure.  
6. Lock the gun 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 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.

Operation/Maintenance  
9. Use the air regulator to control the pump speed  
Starting and Adjusting the Pump  
and fluid pressure. Always use the lowest pressure  
necessary to achieve the desired results. Higher  
pressures waste fluid and cause premature wear  
of the pump packings and spray tip.  
1. Be sure the air regulator and bleed-type master air  
valve are closed.  
NOTE: Do not install the spray tip yet!  
2. Open the bleed-type master air valve.  
CAUTION  
3. Hold a metal part of the spray gun firmly to the  
side of a grounded metal pail and trigger the gun.  
Do not allow the pump to run dry. It will quickly  
accelerate to a high speed, causing damage. If your  
pump is running too fast, stop it immediately and  
check the fluid supply. If the container is empty and  
air has been pumped into the lines, refill the con-  
tainer and prime the pump and the lines, or flush and  
leave it filled with a compatible solvent. Eliminate all  
air from the fluid system.  
4. Slowly open the air regulator until the pump starts.  
5. Allow the pump to cycle slowly until all the air is  
pushed out of the fluid lines.  
6. Release the gun trigger and lock the trigger safety;  
the pump will stall against the pressure.  
Heated Circulating Systems  
7. With the pump and lines primed, and with ade-  
quate air pressure and volume supplied, the pump  
will start and stop as the spray gun is triggered and  
released.  
Operating instructions for a heated circulating system  
are provided in the Viscon HP Heater manual,  
309524. Read and understand all warnings and in-  
structions in the heater manual before operating a  
heated system.  
WARNING  
To reduce the risk of serious injury whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure on page 14.  
1. The three-way ball valve (40) selects either fluid  
circulation or draining. To circulate fluid back to the  
pump, turn the handle toward the CIRC end of the  
valve.  
8. Relieve the pressure, then install the spray tip in  
the gun.  
2. To drain the fluid, turn the handle toward the  
DRAIN end.

Operation/Maintenance  
Shutdown and Care of the Pump  
CAUTION  
Never leave water or water-base fluid in the pump  
overnight. If you are pumping water-base fluid, flush  
with water first, then with a rust inhibitor such as  
mineral spirits. Relieve the pressure, but leave the  
rust inhibitor in the pump to protect the parts from  
corrosion.  
WARNING  
To reduce the risk of serious injury whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure on page 14.  
For overnight shutdown, stop the pump at the bottom  
of its stroke to prevent fluid from drying on the ex-  
posed displacement rod and damaging the throat  
packings. Relieve the pressure.  
WARNING  
To reduce the risk of serious injury whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure on page 14.  
Always flush the pump before the fluid dries on the  
displacement rod. See Flushing below.  
Flushing  
1. Relieve the pressure.  
WARNING  
2. Remove the spray tip from the gun.  
FIRE AND EXPLOSION HAZARD  
Before flushing, read the section FIRE  
OR EXPLOSION HAZARD on page 4.  
Be sure the entire system and flushing  
pails are properly grounded. Refer to  
Grounding on page 5.  
3. Hold a metal part of the gun firmly to the side of a  
grounded metal pail.  
4. Start the pump. Always use the lowest possible  
fluid pressure when flushing.  
5. Trigger the gun.  
Flush with a fluid that is compatible with the fluid you  
are pumping and with the wetted parts in your system.  
Check with your fluid manufacturer or supplier for  
recommended flushing fluids and flushing frequency.  
Always flush the pump before fluid dries on the dis-  
placement rod.  
6. Flush the system until clear solvent flows from the  
gun.  
7. Relieve the pressure.

Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be  
defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written  
recommendations.  
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by  
faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or sub-  
stitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of  
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,  
installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.  
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for  
verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The  
equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect  
in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and  
transportation.  
THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT  
NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.  
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other  
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any  
other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
