PUMP PRIMING & STARTUP
,
CONTINUED
5. With pump operating at high pressure, open two or more faucets and slowly unscrew
the flow control screw until maximum flow is obtained. This steady pressure will be
minimum operating pressure and should agree with the pressure shown below. The
flow control screw diverts the proper amount of water to operate the ejector (Fig. 5).
The correct control valve setting will depend on the type of well installation and pressure switch setting for the particular pump.
NOTE: If the pump is being used for shallow well applications, the flow control screw should be set
in the full open position.
IMPORTANT:
If the pump fails to prime within five minutes:
Turn power off at the breaker box. Look for leaks or a milky color in the discharged water, which indicates an air leak. Re-prime if necessary,
following steps 1 through 5 above. Reset breaker at the breaker box. All connections must be water and air tight in order for pump to operate.
