is LIT. This means that power is being supplied to the control

close attention when running the pump in this mode.
DAMAGE to the pump may occur if pump is not immersed
in water.
5. To operate the pump automatically (float switches), place the
3-position operation switch in the AUTO position (Figure 13).
6. In the AUTO mode the pump will run as long as there is a
sufficient amount of water. This amount is determined by
the setting of the float switches. The
stop float
switch
contacts will open when the water level is low and power
will be removed from the pump's motor.
Once the water level has risen back to the appropriate
level the
start float
switch contacts will close and power
will be restored to the pump's motor.
