NOTE: In the event of a power failure, the shut-off valve 
should be closed, if the restarting of the pump is not 
desirable once power is regained.

AIR-OPERATED PUMPS: To stop the pump from operating 
in an emergency situation, simply close the shut-off valve 
(user-supplied) installed in the air supply line. A properly 
functioning valve will stop the air supply to the pump, 
therefore stopping output. This shut-off valve should be 
located far enough away from the pumping equipment 
such that it can be reached safely in an emergency 
situation.
