It should be in auto normally. That will allow the pump to run automatically when the level activates the on float. Off will cut it off and it will not function at all. On will run the pump and it will not stop until you turn it off. Only run it in auto.
The On/Off switch should be in the On position and the Hand/Off/Auto (HOA) should be in the Auto Position for your typical day to day use. The Hand position is manual run and can be used to drain the tank for service or any other need. NOTE: Do not forget the pump in Hand mode as this may result in the pump running dry risking damage to the pump and/or over saturation to where the pump is moving fluid to.
So should the switch always be on auto or should it be on off
