Accessories
Install the following required accessories in the order
shown in FIG. 5 and FIG. 6, using adapters as neces-
sary. See Kits and Accessories starting on page 53.
•Fluid filter (Y-Strainer) (included in M): with a 60
mesh (250 micron) stainless steel element to filter
particles from the fluid before in reaches the pump.
•Fluid shutoff valves (N): shuts off fluid flow.
•Pressure relief valve (F): overload protection.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid con-
taminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See

Choosing an Installation
Location
• Select a location that will adequately support the
weight of the pump, as well as all plumbing and
electrical connections.
• Refer to the mounting hole layout provided in
Dimensions starting on page 55.
• Always mount the pump upright.
• If you have a mounting configuration that requires
installation in a manner different than depicted in
FIG. 5 or FIG. 6, please contact your Graco distribu-
tor for assistance.
Fluid Connections
1. Remove and discard plugs on check valves.
2. Connect a 1/4 npt(f) fluid line from the fluid source to
the inlet check valve (K). See FIG. 5 on page 16, or
FIG. 6 on page 17.
3. Install a pressure relief valve (F) on the outlet side of
the pump.
NOTE: A pressure relief valve is available from Graco
and can be connected back to the tank or directly to the
inlet side of the pump. See Kits and Accessories on
page 53.
4. Set the pressure relief valve at or below the maxi-
mum working pressure of the pump.
5. Connect a 1/4 npt(f) fluid line from the outlet check
valve (L) to the injection point.
6. Connect a 10-32 UNF fluid outlet from the
prime/bleed valve (21) to the fluid source or waste
reservoir.
Motor Electrical Connections
In the event of an injection line blockage, to reduce the
risk of skin injection and damage to the pump, ensure
the pressure relief valve is set at or below the maxi-
mum working pressure of the pump.
To reduce the risk of electrical shock;
• All electrical wiring must be done by a qualified
electricianand comply with alllocal codes and reg-
ulations.
• Installthe pumpwith a dedicatedmeans todiscon-
nect the main power to the pump.
NOTICE
Branch circuit protection (user supplied) is required on
all models. To avoid equipment damage:
• Never operate the pump without branch circuit
protection installed.
• Branch circuit protection of the correct voltage
and amperage must be installed in line with the
power entry to the system.
• Branch circuit protection should be UL248
approved.
• See table below for branch circuit protection
rating.
