Installation

The reference letters in the following instructions refer
to Typical Installation, page 7.

Grounding

The equipment must be bonded (grounded) directly
to the truck. Grounding reduces the risk of static
shock due to static build up on the equipment.
System Configuration and
Wiring
NOTE: Cable wiring harness kits are available from
Graco. See Cable Harness Kits (all models), page 15,
for a complete list of available kits.

Fuses

NOTICE
Fuses (user supplied) are required on all models. To
avoid equipment damage:
Never operate the Dyna-Star Pump models without
a fuse installed.
A fuse of the correct voltage and amperage must be
installed in line with the power entry to the system.
The recommended fuses are 35A.

Reservoir Installation

Mount the equipment securely so that it cannot move
around during operation. Failure to do so could result
in injury or equipment damage.

Reservoir

1. Install the reservoir in a location that adequately
supports the weight of the reservoir when filled with
lubricant and also provides easy operator access to
the fill port (G) and lubricant outlet connection (A).
2. Connect the high-pressure lubricant supply line (D)
to the lubricant outlet connection (A).
3. Ground the system, see Grounding, page 9. Mount
the reservoir to the grounded chassis member.

Pump

Follow the pump installation instructions provided in
the Dyna-Star HP and HF Pump manual, see Related
Manuals, page 1, provided with the system.

Vent Valve Kit

The vent valve reduces system pressure and allows the
injector to reset. When energized, grease is pumped
through the outlet port (marked 0) on the vent valve;
when de-energized, it vents pressure internally to the
tank.
For installation and operation instructions, see the
Dyna-Star HP Vent V.alve kit manual, see Related
Manuals, page 1.

Auto-Fill Shut Off

The auto-fill shut off refills the grease reservoir instead
of using the fill port (G). When the grease level in the
tank is full, the auto-fill shut off automatically ends the
filling operation. For installation and operation
instructions, see the Dyna-Star HP and HF Pump
Auto-Fill Shut Off Kit manual, see Related Manuals,
page 1.
