Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever

you see this symbol.

NOTE: Always discharge fluid into an approved con-

tainer or location.

1. Shut off all fluid and pneumatic lines (A, K, & P)

using shutoff valves (H & B).

2. Use a flathead screwdriver to turn the prime/bleed

valve (107) slowly counter-clockwise to relieve pres-

sure. (Use a hex wrench to turn the prime/bleed

valve housing (106) on PCI-xxx-xxH pumps. See

Configuration Number Matrix, page 4.)

3. Slowly disconnect fluid lines (K & P) from check

valves (L & M).

Flush the Equipment

• 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 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.

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.

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.
