Installation Instructions

•
Group injectors to minimize feed line length.
•
Install injectors in locations that allow easy and safe
servicing access.
•
Install injectors in areas that minimize accidental
injector damage by 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.
1. Relieve pressure. See Pressure Relief Procedure,
in the pump instruction manual included with your
automatic lubrication system.
2. Install injectors on a flat, hard surface using mount-
ing brackets.
3. Connect fluid supply line to injectors.
NOTICE
To prevent rupturing supply lines due to over-pressur-
izing the components, only use supply lines and fit-
tings that meet or exceed the pressure rating of the
injectors.
4. Connect lube point feed lines.
5. Flush the system with low viscosity oil or mineral
spirits to remove contamination introduced during
installation.

6. 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.
7. Run the system at full output and verify that all injec-
tors are cycling.
8. Adjust injector volume output. (See Volume Adjust-
ment page 2.)
9. Connect feed lines to lubrication points.
Volume Adjustment
*Maximum adjustment setting is when adjusting screw
(2) is just making contact with the indicator pin (8) with
no inlet pressure. Turn adjusting screw clockwise (in), to
reduce output. To adjust, loosen lock nut (3) and turn
adjusting screw (2) the number of turns indicated on the
GL-1 Volume Adjustment Table to obtain the desired vol-
ume. Tighten lock nut (3) when desired volume setting is
reached
.
