If you have an application, or mounting configuration,
that requires installation in a manner different than
depicted in F
IG
. 2, please contact your Graco distributor
for assistance.
NOTE: A y-strainer (G) or chemical filter is required
before the pump inlet. This will keep any debris from the
tank from reaching the pump seals. Fluid filters are
available from Graco. See Kits and Accessories on
page 43.
1. Mount the pump (F) and connect the fluid inlet
line (K).
The pump is designed to be vertically mounted directly
from the 1/4 female NPT inlet port (L). The inlet port (L)
is on the bottom and is designated by a flow arrow point-
ing into the pump. Verify the inlet plumbing is sufficiently
strong to support the weight of the pump.
