Installation
The top of the surge tank must always be supported.
Typical Mountings
See Accessories on page 13 for mounting clamps.
See Fig. 1 for typical mountings. See page 14 for the
mounting hole layout.
Surge tanks must always be mounted upright, as
shown in Fig. 1, not horizontally.
Install the surge tank or filter near the pump outlet.
Position the surge tank so the labels face away from
the pump and so the setscrews, near the top and
bottom of the tank, face toward the pump.

Surge Tank Conversion Kits
Connect the surge tank to the fluid outlet (F) of the
displacement pump and install the clamp in the option-
al outlet (E) at the base of the air motor. See Fig. 2.
Surge Tank Conversion Kits 238634 and
237704
Use Conversion Kits 238634 or 237704 to add a surge
tank to a pump. Kit 238634 includes surge tank
238623 (A) and clamp 238630 (B). Kit 237704 includes
surge tank 214624 (A), clamp 238630 (B), and attach-
ing hardware (C).

Operation
Before operating the equipment, be sure the drain
valve is closed.
Be sure the drain valve is fully closed when spraying
and fully open when draining or circulating fluid to get
the best results and reduce wear on the valve.
Flush the equipment with a compatible solvent to
remove oil used for factory testing and rust prevention.
If you notice excessive surging at the spray gun, shut
off the pump, trigger the gun to relieve fluid pressure,
and open the drain valve (D) at the bottom of the surge
tank. See Fig. 3. After the tank is drained, close the
drain valve and resume operation.

Service
Pressure Relief Procedure
Service Notes
Clean all parts thoroughly when disassembling. Check
parts carefully for damage or wear, replace as needed.
WARNING
SKIN INJECTION HAZARD
Numbers in parentheses in the text refer to the parts
drawings.
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
Check periodically for leakage from the small holes
near the top and bottom of the surge tanks. If you find
leakage at the holes or anywhere else, replace the
seals promptly.
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:
Before removing the end plug and adapter from the
surge tank, loosen the setscrews (5) near the bottom
of the tank (6). See the parts drawings on pages 7
through 12.
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.
Inspect the sealing surfaces for nicks or scratches that
might cause leakage. Do not damage the sealing
surfaces.
1. Lock the gun trigger safety.
When reassembling filters after cleaning or servicing,
be sure to install the filter support as shown in the
parts drawings. Do not install it upside down.
2. Turn off the power to the pump.
3. Close any master bleed-type air valves.
4. Unlock the gun trigger safety.
WARNING
Tighten all threaded connections securely. High
pressure fluid can dislodge a loose connection or
allow high pressure fluid to be emitted from the
connection and cause serious injury.
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. Place a pail under the drain valve, and open the
drain valve to be sure all fluid pressure is relieved.
Keep hands away from the end of the drain valve
when opening it.
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.

The 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 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 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
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.
