Operation
Start and Adjust the Pump
1.Be sure the pump is properly grounded. Refer to Grounding, page 8 .
2.Ensure the High/Low pressure lever is in the “Low” position before starting the pump.
3.Check all fittings to be sure they are tight. Use a compatible liquid thread sealant on all male threads. Tighten fluid inlet and outlet fittings securely.
4.Place the suction tube (if used) in the 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 and may result in pump damage.
5.Place the end of the fluid hose into an appropriate container.
6.Close the fluid drain valve.
7.Turn the air regulator knob to 0. Open all
8.If the fluid hose has a dispensing device, hold it open.
9.Slowly increase air pressure with the air regulator 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.
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.
10.If you are flushing, run the pump long enough to thoroughly clean the pump and hoses.
11.Close the dispensing valve, if used.
12.Close the
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 13.
