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 whenever you stop pumping and before you clean, check, or ser- vice the equipment.
1.Shut off the air supply to the pump.
2.Open the dispensing valve, if used.
3.Open the fluid drain valve (F) to relieve fluid pres- sure. Have a container ready to catch the drainage.
Flush the Pump Before First Use
The pump was tested in water. If water could contami- nate the fluid you are pumping, flush the pump thor- oughly with a compatible solvent. See Flushing and Storage, page 13.
Start and Adjust the Pump
1.Be sure the pump is properly grounded. Refer to Ground the System on page 9.
2.Check fittings to be sure they are tight. Use a com- patible 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 (F).
6.Back out the air regulator knob (C), and open all
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.
