1. Be sure the pump is properly grounded. See
Ground The System, page 12 .
2. Check fittings to be sure they are tight. Use a
compatible liquid thread sealant on male threads.
Tighten fluid inlet and fluid outlet fittings securely.
3. Place the suction tube (if used) in fluid to be
pumped.
NOTE: NOTE: NOTE: If fluid inlet pressure to the pump is more
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 (L).
6. Turn the air regulator knob (R) to match the
desired fluid stall pressure. Open all bleed-type
master air valves.
7. If the fluid hose has a dispensing device, hold it
open. Be sure all fluid shutoff valves are open.
8. Set the desired frequency on the VFD.
9. Start the VFD.
10. If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses.
Pressure Pressure Pressure Relief Relief Relief Procedure Procedure 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. Stop the VFD to remove power to the motor.
2. Open the fluid drain valve (L) to relieve fluid
pressure. Have a container ready to catch the
drainage.
3. Remove supply air to the pump:
