Operation

Pressure Relief Procedure

WARNING

To reduce the risk of serious injury, including splashing fluid in the eyes or on the skin, follow this procedure whenever you are instructed to relieve pressure, when you shut off the pump, and before you check, adjust, clean, move, or repair any system equipment.

1.Shut off air and reserve air to the pump.

2.Open the dispensing valve if the system has one.

3.Open the fluid drain valve to relieve all system pressure, and have a container ready to catch the drainage.

Flushing the Pump Before First Use

The pump was tested in water. If water could contami- nate the fluid you are pumping, flush it thoroughly with a compatible solvent. Follow the procedure in Start- ing and Adjusting the Pump.

Starting and Adjusting the Pump

WARNING

To reduce the risk of serious injury, splashing in the eyes or on the skin, and toxic fluid spills, never move or lift a pump under pressure. If the pump is dropped, the fluid section could rupture. Always follow the Pressure Relief Procedure above before you move or lift the pump.

1.Be sure the pump is properly grounded. Read and follow the instructions in Grounding on page 4.

2.Check all fittings to be sure they are tight. Be sure to use a compatible liquid thread sealant on all male threads. Tighten the fluid inlet and outlet fit- tings and plugs securely. Retorque all fasteners before start-up. See Torque Sequence, page 18.

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

4.Place the end of the outlet hose into an appropri- ate container.

5.Close the fluid drain valve.

6.With the air regulator closed, open all bleed-type master air valves.

7.If the outlet hose has a dispensing device, hold it open while continuing with step 8.

8.Slowly open the air regulator until the pump starts to cycle. Allow the pump to cycle until all air is pushed out of the lines and the pump is primed.

NOTE: To prime a remote solenoid-operated air valve, operate the pump at a minimum 60 cpm rate until the pump is fully primed.

Pump Shutdown

At the end of the work shift, and before you check, adjust, clean, or repair the system, relieve air and fluid pressure.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure at left.
