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 skin injection and splashing
fluid, follow the Pressure Relief Procedure when
you stop dispensing and before cleaning, checking, or
servicing the equipment.
NOTE: Always discharge fluid into an approved con-
tainer or location.
1. Disconnect main power from pump.
2. Shut off the inlet and outlet lines using shutoff
valves (N).
3. Slowly crack the fitting connected to the outlet check
valve (216) to relieve downstream fluid pressure.
4. Open the bleed valve (214) by turning needle
counter-clockwise with a flathead screwdriver to
relieve internal pump fluid pressure.
5. Disconnect and cap inlet and outlet fluid lines.

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.
•
Check fittings for leaks and tighten as necessary.
•
Flush with a fluid that is compatible with the fluid
being dispensed and the equipment's wetted parts.
1. Follow the Pressure Relief Procedure.
2. Connect inlet to the supply source of the flushing
fluid.
3. Connect outlet to a waste reservoir.
4. Run the pump until the dispensed fluid is predomi-
nately flushing fluid.
5. Follow the Pressure Relief Procedure.
Prime the Pump
1. Verify all connections and fluid lines are tight.
2. In order to prime the pump, turn the prime valve
(214) counter-clockwise.
3. Turn the pump on and begin cycling.
4. The pump is primed when discharge from the prime
valve (214) has transitioned from air, to bubbly liquid
chemical, to pure liquid chemical.
5. Close the prime valve (214) tightly and verify that
fluid has stopped draining from the port.
