Start the panel by turning the door interlocking general switch, a green led will indicate that the panel is operating.
The pumps start automatically when an input from a float switch or pressure switch occurs.
The pumps exchangeover permits both pumps to alternate at each start of the motors, should the system require to have both the motors running, the second motor will start with 4” delay.
