NOTICE
Contaminants can damage the seal packing. To
prevent damage to the seal, a filter should be
installed in the grease supply line.
•
Group injectors to minimize feed line length.
•
Install injectors in locations that allow easy servicing
access.
•
To avoid injector damage install injectors in areas
away from moving equipment.
•
Injector outputs can be combined for a common
bearing point with a large grease requirement but
the output for a single injector cannot be split into
multiple bearing points.
•
Graco recommends using steel tubing instead of
pipe and hose for supply lines when possible. Pipe
is often contaminated with scale and requires
proper cleaning prior to use. Hose lines expand
under pressure which leads to longer pump cycle
time.

NOTE: The equipment may be pressurized by an auto-
matic lube cycle initiated by a lubrication controller
(timer).
1. Before installing the injectors, disconnect and iso-
late the power supplies to the lubrication controller
and to the pump.
2. Relieve pressure. See the pressure relief procedure
provided in the pump manual for your system.
3. Install injectors on a flat, hard surface using holes
(a) (F
. 1) in manifold.

4. Connect fluid supply line to injectors.
5. Connect lube point feed lines to outlet (b).
6. Flush the system with low viscosity oil or mineral
spirits to remove contamination introduced during
installation.
7. Use a purge gun or run the pump until clean lubri-
cant is dispensed at the end of each feed line to
purge the system of flushing fluid or air.
8. Run the system at full output and verify that all injec-
tors are cycling.
9. Adjust injector volume output. (See Volume Adjust-
ment page 5.)
10. Connect feed lines to lubrication points.
Injector Cap (F
1. Apply a light coating of transparent lubricant to the
inside of cap (c).
2. Slide the o-ring (d) over the indicator stem of the
injector and into the groove.
3. Slide cap (c) down over the indicator stem of the
injector.
