Pressure Relief Procedure
The equipment stays pressurized until pressure is man-
ually relieved. To reduce the risk of serious injury from
pressurized fluid, accidental spray from the dispense
valve, or splashing fluid, follow this Pressure Relief
Procedure when you:
• are instructed to relieve pressure.
• check, clean, or service any system equipment.
• install or clean fluid nozzles or filter.
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.
Grounding
Proper grounding is an essential part of maintaining a
safe system. The movement of fluids through the dis-
pensing system generates static electricity. Static elec-
tricity can cause fumes to ignite, resulting in explosion
and fire. To reduce the risk of static sparking, ground all
system components per local and national electrical
codes. Refer to user manuals for pump and other sys-
tem components to ground the following:
•Pump: Follow manufacturer’s recommenda-
tions.
•Air and Fluid hoses: Use only grounded
hoses.
•Air compressor: Follow the manufacturer’s
recommendations.
•Fluid supply container: Follow the local code.
To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of valve
firmly to side of grounded metal pail, then trigger valve.
Pre–Installation Procedure
1. Install the battery. See Replacing the Battery on
page 30.
2. Follow the Pressure Relief Procedure.
3. Close the shut–off valve (B, FIG. 1, page 5).
4. Ground the hose and reel or console. See
Grounding.
Installation Procedure
If this is an existing installation, go to step 7. Steps 1 - 6
are the Flushing Procedure.
1. Close the fluid shutoff valve (B, FIG. 3) at each dis-
pense position.
2. Make sure:
• the main fluid outlet valve at the pump is closed,
• the air pressure to the pump motor is adjusted,
• the air valve is open.
3. Slowly open main fluid valve.
Leave a minimum of two engaged threads bare
when using PTFE tape. The bare threads ensure a
ground is maintained.
NOTICE
If this is a new installation or if there is contaminated
fluid in the lines, flush the lines before you install the
metered valve. Contaminated lines could cause the
valve to leak.

a. Place the hose end (with no dispense valve
connected) into a container for waste oil.
b. Secure the hose in the container so it will not
come out during flushing.
c. If you have multiple dispense positions, first
flush the dispense position farthest from the
pump, then work your way toward the pump.
5. Slowly open the shut–off valve (B, FIG. 4) at the dis-
pense position. Flush out a sufficient amount of oil
to ensure that the entire system is clean. Close the
valve.
6. Repeat step 5 at all other dispense positions.
