Before mounting and using the pump for the
first time, check and retorque all external bolts.
Remove all protective bolt covers (37). Follow

Torque Instructions, page 22

to tighten all bolts.

Replace the bolt covers (37). After the first day of
operation, retorque the bolts. Retorque the bolts if the
pump has been idle for an extended time, been used
in thermal cycling applications, been disassembled,
or if there is a large difference between environmental
temperatures and fluid temperatures.

The pump was tested in water. If water could

NOTICE

NOTICE

NOTICE

To avoid damage to your pump, be certain that all
pumped fluids are compatible with wetted parts.
See

Technical Data, page 31

.

1.

Be sure the pump is properly grounded. See

Ground The System, page 10

.

2.

Check fittings to be sure they are tight. Use a
compatible liquid thread sealant on male threads.

NOTICE

NOTICE

NOTICE

Do not overtighten fluid inlet and outlet fittings.
The soft plastic threads can be stripped easily.

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 (F).

6.

Back out the air regulator knob and 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:

NOTE:

NOTE: Use lowest possible air pressure to prime,
just enough to cycle the pump. If the pump does
not prime as expected, turn air pressure DOWN.

DOWN.

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.
