Installation
General Information
• The Typical Installation shown in Fig. 2 is only a
guide for selecting and installing system compo-
nents. Contact your Graco distributor for assistance
in planning a system to suit your needs.
• Always use Genuine Graco Parts and Accessories.
• Reference numbers and letters in parentheses refer

page 28.
Tighten Clamps Before First Use
After you unpack the pump, and before you use it for the
first time, check the fluid and air connection clamps, and
tighten as necessary.
Grounding
•Pump: Connect a ground wire and clamp as shown
in Fig. 1. Loosen the grounding screw (W). Insert
one end of a 12 ga (1.5 mm²) minimum ground wire
(Y) behind the grounding screw and tighten the
screw securely. Connect the clamp end of the
ground wire to a true earth ground.
FIG. 1
•Fluid hoses: Use only grounded hoses with a maxi-
mum of 500 ft. (150 m) combined hose length to
ensure grounding continuity.
•Air compressor: Follow the manufacturer’s recom-
mendations.
•Fluid supply container: Follow the local code.
CAUTION
The pump is very heavy (see Technical Data on
pages 35 for specific weights). If the pump must be
moved, follow the Pressure Relief Procedure on
page 13 and have two people lift the pump by grasp-
ing the outlet manifold securely, or use appropriate lift-
ing equipment.
WARNING
Read the TOXIC FLUID HAZARD warnings on page 5.
Read the BURN HAZARD warnings on page 5. To
reduce the risk of serious injury due to burns, insulate
and/or label the pump before pumping fluids above
110°F (43°C).

Mountings
• Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as well
as the stress caused during operation.
• For ease of operation and service, mount the pump
so the air valve cover (2), air inlet, and fluid inlet and
outlet ports are easily accessible.
Air Line
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 accesso-
ries is grounded.
a. Install an air regulator (C) and gauge to control
the fluid pressure. The fluid outlet pressure will
be the same as the setting of the air regulator.
b. Locate one bleed-type master air valve (B)
close to the pump and use it to relieve trapped
air. See the WARNING above. Locate the other
master air valve (E) upstream from all air line
accessories and use it to isolate them during
cleaning and repair.
c. The air line filter (F) removes harmful dirt and
moisture from the compressed air supply.
2. Install a grounded, flexible air hose (A) between the
accessories and the 1/2 npt(f) pump air inlet (N).
Use a minimum 3/8” (9.5 mm) ID air hose. Screw an
air line quick disconnect coupler (D) onto the end of
the air hose (A), and screw the mating fitting into the
pump air inlet snugly. Do not connect the coupler
(D) to the fitting until you are ready to operate the
pump.
Fluid Suction Line
1. Use flexible, grounded fluid hoses (G) where possi-
ble.
2. For best sealing results, use a standard Tri-Clamp®
style sanitary gasket of a flexible material such as
Buna-N, Viton, or silicon.
3. If the fluid inlet pressure to the pump is more than
25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in ineffi-
cient pump operation.
4. At inlet fluid pressures greater than 15 psi (0.1 MPa,
1 bar), diaphragm life will be shortened.
5. See the Technical Data on pages 35 for maximum
suction lift (wet and dry).
Fluid Outlet Line
1. Use flexible, grounded fluid hoses (L) where possi-
ble.
2. For best sealing results, use a standard Tri-Clamp®
style sanitary gasket of a flexible material such as
Buna-N, Viton, or silicon
3. Install a fluid drain valve (J) near the fluid outlet. See
the WARNING above, and FIG. 2.
4. Install a shutoff valve (K) in the fluid outlet line.
CAUTION
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants could
affect your fluid supply. See Air Exhaust Ventilation
on page 10.
WARNING
A bleed-type master air valve (B) is required in the
system to relieve air trapped between this valve and
the pump. 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 contamination from hazardous
fluids. See FIG. 2.
WARNING
A fluid drain valve (J) is required to relieve pressure in
the hose if it is plugged. 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. See FIG. 2.

Air Exhaust Ventilation
The air exhaust port is 3/4 npt(f). Do not restrict the air
exhaust port. Excessive exhaust restriction can cause
erratic pump operation.
To provide a remote exhaust:
1. Remove the muffler (P) from the pump air exhaust
port.
2. Install a grounded air exhaust hose (T) and connect
the muffler (P) to the other end of the hose. The
minimum size for the air exhaust hose is 3/4 in. (19
mm) ID. If a hose longer than 15 ft. (4.57 m) is
required, use a larger diameter hose. Avoid sharp
bends or kinks in the hose.
3. Place a container (U) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures. See
FIG. 4.
FIG. 4 Venting Exhaust Air
WARNING
Read the FIRE AND EXPLOSION HAZARD and
TOXIC FLUID OR FUMES HAZARD warnings on
page 5 before operating this pump.
Be sure the system is properly ventilated for your type
of installation. You must vent the exhaust to a safe
place, away from people, animals, food handling
areas, and all sources of ignition when pumping flam-
mable or hazardous fluids.
Diaphragm failure can cause the fluid being pumped
to exhaust with the air. Place an appropriate container
at the end of the air exhaust line to catch the fluid. See
FIG. 4.
