Pressure Relief Procedure
Read the warnings on page 3, and follow the Pres- sure Relief procedure below whenever you:
•are instructed to relieve pressure
•stop spraying
•check or service any of the equipment
•install or clean the fluid nozzle.
1.Shut off the air to the pump.
2.Open the dispensing valve, if used.
3.Open the fluid drain valve to relieve all fluid pres- sure, having a container ready to catch the drainage.
Flushing the Pump Before First Use
The pump was tested in oil. If oil could contaminate the fluid you are pumping, flush the pump thoroughly with a compatible flushing fluid. Follow the steps under Start- ing and Adjusting the Pump.
Starting and Adjusting the Pump
1.Be sure the pump is properly grounded. Refer to Grounding on page 9.
2.Check all fittings to be sure they are tight. Be sure to use a compatible liquid thread sealant on all male threads.
3.Place the suction tube (L) in the fluid to be pumped.
4.Place the end of the fluid hose (P), see FIG. 2, into an appropriate container.
5.Close the fluid drain valve (J).
6.With the pump air regulator (F) closed, open the
7.If the fluid hose has a dispensing device, hold it open while continuing with the following step.
8.Slowly open the air regulator (F) until the pump starts to cycle. Allow the pump to cycle slowly until all air is pushed out of the lines and the pump is primed.
If you are flushing, run the pump long enough to thor- oughly clean the pump and hoses. Close the air regula- tor. Remove the suction tube (L) from compatible flushing fluid and place it in the fluid to be pumped.
NOTE: Operating the pump dry for extended periods or operating at pressures higher than the recommended maximum input air pressure will reduce diaphragm life.
Pump Shutdown
Short Term Shutdown
For a short term shutdown, relieve the pressure (see procedure on this page).
Long Term Shutdown
For a long term shutdown, such as several hours or overnight:
1.Flush the pump thoroughly.
2.Leave compatible flushing fluid in the pump.
3.Relieve the pressure (see procedure on this page).
