Hi! I just bought a townhouse and the float switch to the AC unit has been disconnected. It's a Carrier Model FB4A. I've got the float switch. Can someone please give me instructions on how to reattach it?? Thank you!!!!

If you can find the wires in or at the unit that go to the thermostat, one will probably be red and or attached to a terminal on a board marked "R". You want the two wires of your float to be in series with that wire
