Fig. 1: Manifolds 241161 and 241162  
Models 239786 and 241469  
with Manifolds 241161 and 241162  
The gun is supplied with an internal fluid plug (4). See  
Fig. 1. To use the gun in a circulating system, remove  
the internal plug. In a non-circulating system, leave the  
plug in place to minimize flush time.  
The gun is supplied with an internal fluid filter (32).  
Install the filter in the gun port being used as the fluid  
inlet (see Fig. 1).  
NOTE: The gun can operate without the filter. If you  
are using highly viscous fluid and the filter causes an  
unacceptable pressure drop, remove the filter.  
In a circulating system, apply anti-seize lubricant  
222955 to the threads and mating faces of the man-  
ifold (101) and the elbows (107), supplied unas-  
sembled. Install elbows (107) in both fluid ports of the  
manifold (101). Connect the fluid supply line to one  
elbow and the fluid return line to the other. The man-  
ifold fluid ports are reversible.  
Install the gun on the manifold, using the four screws  
(17). Thread the screws by hand, then torque alter-  
nately and evenly to 65 in-lb (7.3 NSm).  
In a non-circulating system, apply anti-seize lubricant  
222955 to the threads and mating faces of the man-  
ifold (101), a plug (109), and an elbow (107), supplied  
unassembled. Install an elbow (107) in one fluid port of  
the manifold, and a plug (109) in the other port. Install  
the internal plug (4) in the gun fluid port on the same  
side as the manifold plug. Connect the fluid supply line  
to the manifold elbow. See Fig. 1.  
Models 233670  
with Manifold 244930  
This gun and manifold are designed to be used with  
high viscosity material and sealants, such as protective  
coatings and automotive sealants. There is no circula-  
tion port. The fluid inlet uses both ports to feed the  
valve and no filter is used.

Air Line and Accessory  
Recommendations  
Fluid Line and Accessory  
Recommendations  
1. Install an air pressure regulator on the gun cylinder  
air supply line.  
WARNING  
INJECTION HAZARD  
To reduce the risk of property damage or  
serious injury, including injection, which  
could be caused by component rupture  
or unrelieved fluid pressure,  
A minimum of 70 psi (0.49 MPa, 4.9 bar) air pres-  
sure must be supplied to the cylinder for proper  
operation. Air pressure opens the valve, a spring  
closes the valve. A three-way air valve, which  
exhausts cylinder air, is required.  
D A fluid drain valve(s) is required in your system  
to assist in relieving fluid pressure in the dis-  
placement pump, hose and gun; triggering the  
gun to relieve pressure may not be sufficient.  
2. Install a bleed-type air shutoff valve on the main air  
line. Install an additional bleed-type valve on each  
pump air supply line, downstream of the pump air  
regulator, to relieve air trapped between this valve  
and the pump after the air regulator is shut off.  
D A fluid pressure regulator must be installed in  
the system if the pump’s maximum working  
pressure exceeds the gun’s maximum fluid  
working pressure (see the front cover).  
1. Install a fluid filter and drain valve(s) close to the  
pump’s fluid outlet.  
WARNING  
2. Install a fluid pressure regulator to control fluid  
pressure to the gun.  
The bleed-type air shutoff valve is required in your  
system to relieve air trapped between this valve  
and the pump after the air regulator is closed.  
Trapped air can cause the pump to cycle unexpect-  
edly, which could result in serious injury.  
NOTE: Some applications require fine-tuned control of  
fluid pressure. You can control fluid pressure more  
accurately with a fluid pressure regulator than by  
regulating the air pressure to the pump.  
3. Install a bleed-type air shutoff valve on the gun air  
cylinder supply line, downstream of the air regula-  
tor, to shut off air to the gun cylinder. Connect the  
air supply line to the gun cylinder air inlet (C). See  
Fig. 4.  
3. Install a fluid shutoff valve to shut off the fluid  
supply to the gun.  
4. For paint spray applications, install an in-line fluid  
filter, part no. 210500, on the gun fluid inlet (F) to  
avoid clogging the spray tip with particles from the  
fluid. See Fig. 4.  
NOTE: The cylinder air inlet accepts 1/4 in. (6.3 mm)  
O.D. tubing.  
5. Connect the electrically conductive fluid hose to  
the gun fluid inlet (F) or optional in-line filter.

Ground the System  
the pump: Use only electrically conductive hoses  
with a maximum of 500 feet (150 m) combined  
hose length to ensure grounding continuity. Check  
the electrical resistance of your air and fluid hoses  
at least once a week. If the total resistance to  
ground exceeds 29 megohms, replace the hose  
immediately.  
WARNING  
FIRE AND EXPLOSION HAZARD  
Improper grounding could cause static  
sparking, which could cause a fire or  
explosion. To reduce the risk of property  
damage or serious injury, follow the  
grounding instructions below.  
NOTE: Use a meter that is capable of measuring  
resistance at this level.  
The following grounding instructions are minimum  
requirements for a system. Your system may include  
other equipment or objects which must be grounded.  
Check your local electrical code for detailed grounding  
instructions for your area and type of equipment. Your  
system must be connected to a true earth ground.  
4. Spray gun: Ground the gun by connecting it to a  
properly grounded fluid hose and pump.  
5. Fluid supply container: Ground it according to  
local code.  
6. Object being sprayed: Ground it according to  
1. Pump: Ground the pump by connecting a ground  
wire and clamp between the fluid supply and a true  
earth ground as instructed in your separate pump  
instruction manual.  
local code.  
7. All solvent pails used when flushing: Ground  
them according to local code. Use only metal pails,  
which are conductive. Do not place the pail on a  
non-conductive surface, such as paper or card-  
board, which interrupts the grounding continuity.  
2. Air compressors and hydraulic power sup-  
plies: Ground them according to the manufacturer  
recommendations.

Graco Standard Warranty  
Graco warrants all equipment manufactured by Graco and bearing its name to be free from defects in material and workmanship on the  
date of sale by an authorized Graco distributor to the original purchaser for use. With the exception of any special, extended, or limited  
warranty published by Graco, 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 accor-  
dance 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  
date of sale.  
Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular purpose in connection  
with accessories, equipment, materials or components sold but not manufactured by Graco. These items sold, but not manufactured  
by Graco (such as electric motors, switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide  
purchaser with reasonable assistance in making any claim for breach of these warranties.  
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment  
hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract,  
breach of warranty, the negligence of Graco, or otherwise.
