Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever you see this symbol.

This equipment stays pressurized until pressure is relieved manually. To help prevent serious injury from pressurized fluid, such as splashing in the eyes or on skin, follow the Pressure Relief Procedure when you stop pumping and before you clean, check, or service the equipment.

1.Shut off the air supply to the pump.

2.Open the dispensing valve, if used.

3.Open the fluid drain valve to relieve fluid pressure. Have a container ready to catch the drainage.

Tighten Fasteners

Before mounting and using the pump for the first time, check and retorque all external fasteners. Follow Torque Instructions, page 16, or see the torque tag on your pump. After the first day of operation, retorque the fasteners.

Flush the Pump Before First Use

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 15.

Start and Adjust the Pump

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. Tighten fluid inlet and outlet fittings securely

3.Place the suction tube (if used) in fluid to be pumped.

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

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 0. 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: 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.

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.

Pump Shutdown

At the end of the work shift and before you check, adjust, clean, or repair the system, follow the Pressure Relief Procedure, page 14.
