MODEL I I Panel • <br /> Single phase,duplex alternating pump control with override. • <br /> The Model 122 control panel is designed to alternately control two 120, 208, or 240 VAC single phase pumps in water and <br /> sewage installations. The alternating action equalizes pump wear. In addition to the alternating pump control, this system <br /> provides override control should either pump fail.
