Aquaguard Float Switch Wiring Diagram. Cut the wires, strip them and twist them together. Connect the ribbed wire of the switch, using a wire nut, to the air handler side of the circuit or to terminal in unit.

Connect the second red switch lead to “r” terminal of unit. Most float switches have a float with two wires coming from the top of it where the float can be removed from the fitting. Incorporating both switch wires in the red circuit will shut the unit completely off.
