Installation
Pressure Relief Procedure
Follow the Pressure Relief
Procedure whenever you see this
symbol.
1.
Turn off the power supply to the pump or
close the fluid shut off valve (B).
2.
Open the nozzle. Authorize and activate
a dispense. Trigger the metered
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.
Grounding
Follow manufacturer’s recommendations to
ground the
pump
and
fluid supply
container
.
Ground the
hose
and
reel
or
console
. Leave
at least two threads bare when using PTFE
tape. The bare threads ensure a ground is
maintained.
To maintain grounding continuity when
flushing or relieving pressure:
hold a metal
part of the metered dispense valve firmly to
the side of a grounded metal pail, then trigger
the metered dispense valve.
Hoses:
Only use electrically conductive
hoses. Check electrical resistance of hoses.
If total resistance to ground exceeds 29
megohms, replace the hose immediately.
Pre-Installation Procedure
1.
See Relieve pressure
, page 10.
2.
Close fluid shut-off valve (B, F
3.
Ground the hose and reel or console
(see Grounding, page 10).
4.
Flush equipment. See
, page
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.
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.
FIRE HAZARD
Conductive metal surfaces on the metered
dispense valve must not make contact with
any positively charged metal surface,
including (but not limited to), the starter
solenoid terminal, alternator terminal or
battery terminal. Such contact could cause
electrical arcing and a fire.
NOTICE
•
If this is a new installation or if the fluid
lines are contaminated, flush the lines
before installing the metered dispense
valve. Contaminated lines could cause
the metered dispense valve to leak.
•
Never dispense compressed air with
metered dispense valve. Dispensing
compressed air will damage the
metered dispense valve.
