Grounding
Pump: follow manufacturer’s recommendations.
Hose reels or consoles: connect to a true earth
ground.
Air and fluid hoses: use only conductive hoses.
Air compressor: follow manufacturer’s recommenda -
tions.
Fluid supply container: follow local code.
IM20P 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.
1. Turn off the power supply to the pump.
2. Trigger the dispense valve into a grounded 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 is suspected 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. Then loosen the fitting nut completely.
c. Clear the obstruction in the valve, extension, or
nozzle.
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. 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 Pro -
cedure when you stop dispensing and before clean -
ing, checking, or servicing the equipment.
