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
starting on page 49.
•
Always mount the pump upright.
•
If you have a mounting configuration that requires
installation in a manner different than depicted in
F
IG
. 2, please contact your Graco distributor 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 F
IG
. 2 on page 20.
3.
Install a pressure relief valve (F) on the outlet side of
the pump.
NOTE:
The 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
on
page 48.
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.
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.
