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.
