Abstract
An electrolytic pool purifier system for purifying water in a swimming pool. The system includes an electrolytic cell, located at the discharge end of a water circulation line, and a control circuit The control circuit includes a pump sense circuit for sensing the initiation of the pool pump cycle so as to maximize concurrent operation of the pump and the cell. The control circuit further includes a low current shutdown circuit for terminating operation of the system when a fault in the cell causes a reduction in control circuit current. The low current shutdown circuit includes a current monitor circuit that permits the indirect measurement of current with a voltmeter.
