WARNING
PRESSURIZED EQUIPMENT HAZARD
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
Are instructed to relieve pressure
Check, clean, or service any system equipment
Install or clean fluid nozzles or filter
Pressure Relief Procedure
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.
WARNING
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.
Pre-Installation Procedure
1. Install the battery. See Replacing the Battery on
page 16.
2. Relieve the pressure.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure above.
3. Close the shut-off valve (item J in Fig. 1).
4. Ground the hose and reel or console. See
Grounding on page 6. Do not use PTFE tape
on the pipe joints; it may cause a loss of ground
across the pipe joint.
Installation Procedure
CAUTION
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.
1. If this is an existing installation, go to step 7.
Steps 2 through 6 are the Flushing Procedure .
2. Close the fluid shut-off valve (J) at each dispense
position.
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.
4. Place the hose end (with no dispense valve
connected) 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.
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.
6. Repeat step 5 at all other dispense positions.
7. Relieve the pressure.
WARNING
To reduce the risk of serious injury, whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
8. Slide the swivel cover (4) of the PM5 onto the
hose, small end first. See Fig. 3.
9. Apply thread sealant to the male threads of the
hose fitting, thread the hose fitting into the swivel
(3) of the PM5, and tighten it firmly. See Fig. 3.
NOTE: Make sure you let the sealant cure to the
manufacturer’s recommendations before you let
fluid into the system.
