Installation Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
CAUTION
The equipment stays pressurized until pressure is
manually relieved. To reduce the risk of serious
injury from pressurized fluid, accidental spray from
the dispense valve, or splashing fluid, follow the
Pressure Relief Procedure when you
If this is a new installation, or if the fluid in the
lines is contaminated, flush the lines before you
install the metered valve. Contaminated lines
could cause the valve to leak.
D Are instructed to relieve pressure
D Check, clean, or service any system equipment
D Install or clean fluid nozzles or filter
1. If this is an existing installation, go to step 7.
Steps 2 through 6 are the Flushing Procedure.
Pressure Relief Procedure
2. Close the fluid shut-off valve (J) at each dispense
position.
1. Turn off the power supply to the pump.
3. 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.
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. Place the hose end (with no dispense valve con-
nected) into a container for waste oil. Secure the
hose in the container so it will not come out during
flushing. If you have multiple dispense positions,
first flush the dispense position farthest from the
pump, and work your way toward the pump.
4. Leave the drain valve open until you are ready to
pressurize the system.
WARNING
5. Slowly open the shut-off valve (J) at the dispense
position. Flush out a sufficient amount of oil to
ensure that the entire system is clean, and close
the valve.
FIRE AND EXPLOSION HAZARD
The movement of fluids through the
dispensing system generates static
electricity. The static electricity can
cause volatile fumes to ignite, resulting in explosion
and fire. The dispensing system must grounded.
See Grounding on page 6.
6. Repeat step 5 at all other dispense positions.
7. Relieve the pressure.
Pre-Installation Procedure
WARNING
