Operation

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as splashing fluid, follow the
Pressure Relief Procedure when you stop dispens-
ing and before cleaning, checking, or servicing the
equipment.
NOTE: Always discharge fluid into an approved con-
tainer or location.
1. Turn SPEED knob (H) to off and disconnect power
cord (B).
2. Shut off the inlet and outlet lines using shutoff
valves (C).
3. Slowly crack the fitting connected to the outlet check
valve to relieve downstream fluid pressure.

Flush 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 pos-
sible pressure.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
1. Follow the Pressure Relief Procedure.
2. Connect inlet fluid line (D) to the supply source of
the flushing fluid.
3. Connect outlet fluid line (E) to a waste container.

4. Run the pump until the dispensed fluid is predomi-
nately flushing fluid.
5. Follow the Pressure Relief Procedure.

Prime the Pump

1. Connect power (B) to the pump.
2. Set the STROKE % knob (J) to 100%. (See F
on page 10.)
3. Set the SPEED knob (H) to maximum cycles per
second.
While pump is operating, if fluid begins moving, no fur-
ther priming is required.
If fluid is not moving, open prime/bleed valve (4 or 104)
approximately one turn until fluid begins to move. When
the inlet fluid line (D) fills, close prime/bleed valve (4 or
104).
NOTICE
Do not overtighten prime/bleed valve. Damage may occur.
