b. Locate a bleed-type master air valve (B) close
Air Line
to the pump, to relieve trapped air. See the
WARNING at left. Locate another air valve (E)
upstream from all air line accessories, to
isolate them during cleaning and repair.
WARNING
A bleed-type master air valve (B) is required in your
system to relieve air trapped between this valve
and the pump. See Fig. 2. Trapped air can cause
the pump to cycle unexpectedly, which could result
in serious injury, including splashing in the eyes or
on the skin, injury from moving parts, or contamina-
tion from hazardous fluids.
c. Install an air line filter (D) to remove harmful
contaminants such as dirt, moisture, and oil
from the compressed air supply.
2. The air valve does not require lubrication.
1. Install the air line accessories as shown in Fig. 2.
Mount these accessories on the wall or on a
bracket. Be sure the air line supplying the acces-
sories is electrically conductive.
3. Install an electrically conductive, flexible air hose
(C) between the accessories and the pump air inlet
(T). Use a minimum 1/4” (6.3 mm) ID air hose.
Screw an air line quick disconnect coupler (V) onto
the end of the air hose and screw the mating fitting
into the pump air inlet snugly. Do not connect the
coupler to the fitting yet.
a. The fluid pressure can be controlled in two
ways, either by controlling the air into the
pump with the air regulator (F) or the fluid out
of the pump with the fluid regulator (H).

Fluid Suction Line
CAUTION
Some systems may require installation of a pressure
relief valve at the pump outlet to prevent overpres-
surization and rupture of the pump or hose.
D Screw the suction line (L) into the pump inlet (M)
snugly. Use a compatible liquid thread sealant on
connections to prevent air from getting into the fluid
line.
Thermal expansion of fluid in the outlet line can
cause overpressurization. This can occur when using
long fluid lines exposed to sunlight or ambient heat,
or when pumping from a cool to a warm area (for
example, from an underground tank).

Fluid Outlet Line
D Install a fluid regulator (H) at the pump fluid outlet
to control fluid pressure, if desired. See Air Line,
step 1a, for another method of controlling pressure.
WARNING
A fluid drain valve (J) is required in your system to
relieve pressure in the hose if it is plugged. See
Fig. 2. The drain valve reduces the risk of serious
injury, including splashing in the eyes or on the
skin, or contamination from hazardous fluids when
relieving pressure. Install the valve close to the
pump fluid outlet. To use the valve as a circulation
valve, connect a tube (K) between the valve and
pail.
D Install a fluid drain valve (J) near the fluid outlet.
See the WARNING at left.
Flush the Pump Before First Use
The pump was tested in lightweight oil. If the oil could
contaminate the fluid you are pumping, flush the pump
thoroughly with a compatible solvent. Follow the steps
under Starting and Adjusting the Pump on page 11.

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.
