Installation
Grounding
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes
to ignite or explode. Grounding provides an escape
wire for the electric current.
Pump: follow manufacturer's recommendations.
Hose reels or consoles: connect to a true earth
ground.
Fluid hoses: use only conductive hoses when
dispensing petroleum products.
PM8 and PM20 meters: use thread sealant when
connecting the meter to the hose. Do not use PTFE
tape on the pipe joints, it may cause loss of ground
across the pipe joint.
Waste container while flushing: use a grounded metal
container. Hold hose coupling or metal part of the
meter firmly to the side of the waste container while
flushing.

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
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 dispensing and before
cleaning, checking, or servicing the equipment.
1. Turn off 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 ready to pressurize
the system.
5. If it appears that the valve, extension or nozzle is
clogged or that pressure has not been fully relieved:
a. Very slowly loosen the fitting nut on the hose to
relieve pressure gradually.
b. After the pressure has been relieved, loosen the
fitting nut on the hose completely.
c. Clear the obstruction in the hose or tip.
