2.16 Float Switch: The pump incorporates an integral automatic float switch which
has two modes of operation, auto and manual.
The float switch consists of a float which moves up and down on a vertical
axis within a housing.
2.17 Float Switch Operation: The float switch operation mode is changed by
moving the selection lever (1) either up for the Manual position or down for
the Auto position.
2.18 Automatic Operation (Switch Position ‘Down’): The integrated float starts
and stops the pump automatically when the selection indicator is set to
automatic. It also provides a low level cut out to prevent dry running.
2.19 Manual Operation (Switch Position ‘Up’): To start the pump, lift the selector
lever (1) to the up position. This will cause the pump to run continuously.
In this condition the pump will empty the sump down to a level of 3–6 mm.
The pump must then be manually stopped to avoid dry running and pump
damage.
