Pressure Relief Relief Procedure Procedure
Pressure Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure
is relieved manually. To help prevent serious
injury from pressurized fluid, such as splashing
in the eyes or on skin, follow the Pressure Relief
Procedure when you stop pumping and before you
clean, check, or service the equipment.
1. Shut off the air supply to the pump.
2. Open the dispensing valve, if used.
3. Open the fluid drain valve to relieve fluid
pressure. Have a container ready to catch the
drainage.

3. Place the suction tube (if used) in fluid to be
pumped.
NOTE: If fluid inlet pressure to the pump is more
NOTE: NOTE:
than 25% of outlet working pressure, the ball
check valves will not close fast enough, resulting
in inefficient pump operation.
NOTICE NOTICE NOTICE
Excessive fluid inlet pressure can reduce
diaphragm life.
4. Place the end of the fluid hose into an appropriate
container.
5. Close the fluid drain valve.
6. Turn the air regulator knob to 0. Open all
bleed-type master air valves.
7. If the fluid hose has a dispensing device, hold
it open.
8. Slowly increase air pressure with the air regulator
until the pump just starts to cycle. Allow the
pump to cycle slowly until all air is pushed out of
the lines and the pump is primed.
NOTE: Use lowest possible air pressure to prime, NOTE: NOTE:
just enough to cycle the pump. If the pump does
not prime as expected, turn air pressure DOWN.
9. If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses.
10. Close the bleed-type master air valve.
