Graco Accu-Shot [5/14] Grounding
Installation
309454D 5
Grounding
Refer to the user manuals for the pump and other sys-
tem components, and ground the following:
• Pump: follow the manufacturer’s recommendations.
• Fluid hoses: use only grounded hoses.
• Air compressor: follow the manufacturer’s recom-
mendations.
• Fluid supply container: follow the local codes.
To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the valve
firmly to the side of a grounded metal pail, then trigger
the valve
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Turn off the power supply to the pump.
2. Trigger the dispense valve into a waste container to
relieve pressure.
3. Open any bleed-type master air valves and fluid
drain valves in the system.
4. Leave the drain valve open until you are ready to
pressurize the system.
NOTE: If you suspect the dispensing valve, extension or
grease fitting coupler is clogged, or that pressure has
not been fully relieved after following all the previous
steps, using a rag, VERY SLOWLY loosen the coupler or
hose end coupling and allow pressure to be relieved
gradually, then loosen the part completely and clear the
clog.
Installation Procedure
If this is an existing installation, go to step 6.
1. Close the fluid shut-off valve (A) at each dispense
stations. (Fig 1, page 4)
2. Make sure the main fluid outlet valve at the pump is
closed, the air pressure to the pump motor is
adjusted, and the air valve is open. Slowly open the
main fluid valve.
3. Place the hose end (with no dispense valve con-
nected) into a container for waste grease. Secure
the hose in the container so it will not come out dur-
ing flushing.
NOTE: If you have multiple dispense positions, first flush
the dispense position farthest from the pump, and work
your way toward the pump.
4. Slowly open the shut-off valve (A) at the dispense
station. Flush out a sufficient amount of grease to
ensure that the entire system is clean, and close the
valve. (F
IG. 1, page 4)
5. Repeat step 4 at all other dispense stations.
6. Relieve the pressure. See Pressure Relief Proce-
dure.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
NOTICE
If this is a new installation, or if the grease in the lines
is contaminated, flush the lines before you install the
metered valve. Contaminated lines can cause the
valve to leak or malfunction.
NOTICE
Always ensure that the thread of the hose (or swivel)
is compatible with the thread of the Accu-Shot dis-
pense.
