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
upstream ball 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. Leave the drain valve open until ready to pressurize
the system.
NOTE: If you suspect that the dispense valve or
extension is clogged, or that the pressure has not been
fully relieved after following the above steps, very
slowly loosen the coupler or hose end coupling to
relieve the pressure gradually, then loosen completely.
After doing this, the obstruction can be cleared.
Flush the Equipment
Before installation of the dispense valve to the end of
the hose, flush the line with the fluid being dispensed.
1. Place the end of the hose into a grounded metal
waste container. Hold the hose firmly against the
waste container throughout the flushing process
. 2).
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.
To avoid fire and explosion, always ground
equipment and waste container. To avoid static
sparking and injury from splashing, always flush at
the lowest possible pressure.
