Installation Procedure - Graco Accu-Shot 233807 Instructions And Parts

WARNING
If high-pressure fluid pierces the skin, the injury might
look like "just a cut" but is a serious wound. Get imme-
diate medical attention
• Always shut off power and relieve pressure before
you service or clean fluid dispenser, remove
parts, or repair leaks. See Pressure Relief Pro-
cedure.
• Keep clear of tip, and never point dispenser at
yourself or anyone else.
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. Now clear the
clog.
WARNING
Fire and Explosion Hazard
The movement of fluids through the dis-
pensing system generates static electricity.
The static electricity can cause volatile
fumes to ignite, resulting in explosion and
fire. The dispensing system must be
grounded. See Grounding on page 6.

Installation Procedure

CAUTION
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.
If this is an existing installation, go to step 6.
1. Close the fluid shut-off valve (A) at each dispense
station. See 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. 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.
5. Repeat step 4 at all other dispense stations.
6. Relieve the pressure
WARNING
Pressurized Equipment Hazard
To reduce the risk of serious injury, when-
ever you are instructed to relieve pressure,
always follow the Pressure Relief Proce-
dure on page 4.
