Oldcabin-On the overflow, just put about 6" of water in your pump chamber...put a witness mark with tape (see above).

Turn on pump.

Crank down on the knob from open to close till the sucking stops. Wait a couple minutes and move it a few thousandths to fine tune. Note that the water level in the overflow will be an inch or two below the emergency tube.

It's only hard if your afraid of messing up. The emergency overflow will prevent from flooding tank and running pump dry.
