General Information
• The Typical Installation shown on p. 8 is only
a guide for installing system components and
accessories. It is not an actual system design.
Contact your Graco distributor for assistance in
designing a system to suit your particular needs.
• Always use Genuine Graco Parts and Accessories,
available from your Graco distributor. If you supply
your own accessories, be sure they are adequately
sized and pressure-rated for your system.
• Reference numbers and letters in parentheses
refer to the reference numbers in the figures and
in the Parts Lists.
Instructions Before First Use
Before using the pump:
1. Check that all fluid cover and fluid
manifold fasteners are tight. Follow the
Torque Instructions, page 29.
2. Install muffler (AB).
Mount the Pump
1. For ease of operation and service, mount the
pump so the air inlet (T), fluid inlet (N), and fluid
outlet (M) ports are easily accessible.
NOTE: The arrow labels on the pump show fluid
inlet and outlet directions.
2. Mountthepumpinawell-ventilatedareawith
sufficient clearance on all sides for operator
access and servicing.
3. The air inlet (T) must be on the opposite side of
the pump from the muffler (AB).
4. The pump can be mounted in any orientation.
The fluid manifolds can be rotated to face either
direction.
NOTE: Stand Kit 17H315 is available as a
mounting option.
5. Be sure the mounting can support the weight of
the pump, hoses, and accessories as well as the
stress caused during operation. The pump has
four mounting holes (V) for M10 (3/8 in.) bolts.
See Mounting Dimensions, page 38.
Triton Users Note: The mounting hole pattern is
the same.

Installation
Air Line
1. Install the air line accessories as shown in
Typical Installation, page 8. Use adaptors as
needed. Be sure the air line supplying the
accessories is grounded.
a. Thefluidpressurecanbecontrolledwith
either an air regulator (F) to control the air
into the pump, or with a fluid regulator (H) to
control the fluid out of the pump.
b. Install a bleed-type master air valve (B) close
to the pump. This valve is required in your
system to relieve air trapped between it and
the pump when the valve is closed. Be sure
the bleed valve is easily accessible from the
pump, and is located downstream from the
air regulator.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.
c. Install a second air valve (E) upstream from
all air line accessories to isolate them during
cleaning and repair.
d. Install an air line filter (D) to remove
contaminants such as dirt, moisture, and oil
from the compressed air supply.
2. The air valve on the pump does not require
lubrication.
3. Install a grounded, flexible air hose between
the accessories and the pump air inlet (T). See
Technical Specifications, page 40, to determine
the air inlet size of your pump. Use a minimum
1/2 in. (13 mm) ID air hose.
4. If desired, install an accessory Pressure Limit
Kit in the air line, close to the air inlet. See
Repair Kits, page 35, for the correct kit for your
pump size.

Installation
Fluid Suction Line
•SeeTechnical Specifications, page 40,to
determine the fluid inlet size of your pump.
• For maximum suction lift (wet and dry) information,
see Technical Specifications, page 40.
1. Use flexible, conductive hoses.
2. Use a compatible liquid thread sealant on
connections to prevent air from entering the fluid
line.
3. Attach the suction line into the pump inlet (N)
snugly.
Fluid Outlet Line
1. Use electrically conductive fluid hoses (P). Attach
thefluidfi
tting onto the pump outlet (M) snugly
while supporting the outlet with a wrench. See
Technical Specifications, page 40, to determine
thefluido
utlet size of your pump.
2. Install a fluid regulator (H) at the pump fluid
outlet to control fluid pressure, if desired. See
Air Line,page 7, Step 1a, for an alternative
method to control pressure.
3. Install a fluid drain valve (J) near the fluid outlet.
To use the valve as a circulation valve, connect a
tube (K) between the valve and pail.
A fluid drain (J) valve is required in your system
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.
Some systems may require installation of a
pressure relief valve (not supplied) at the pump
outlet to prevent overpressurization and rupture of
the pump or hose.
Thermal expansion of fluid in the outlet line can
cause overpressurization. Thermal expansion
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).
Overpressurization also can occur if the pump is
used to feed fluid to a piston pump, and the intake
valve of the piston pump does not close, causing
fluid to back up in the outlet line.
