Before mounting and using the pump for the first time,
check and retorque all external fasteners. Follow
Torque Instructions, page 23 , or see the torque
tag on your pump. After the first day of operation,
retorque the fasteners.

The pump was tested in water. If water could
contaminate the fluid you are pumping, flush the
pump thoroughly with a compatible solvent. See
Flushing and Storage, page 22 .

When the air pressure is at least 10 psi higher than
the desired outlet pressure, the pump is in Transfer
Mode and no pulsation damping is occurring. To
reduce outlet pulsation, start by setting the air
pressure
equal
to the desired outlet fluid pressure.
Continue to adjust the air pressure relative to the
outlet fluid pressure. Lower relative air pressures
produce more pulsation damping. Higher relative air
pressures produce better pump efficiency.

1. Be sure the pump is properly grounded. See
Ground The System, page 13 .
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.
6. Turn the air regulator knob 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. Press the start (run) button on the VFD.
10. If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses.
