Q: I have a 20X 25 older unit. My current power supply runs from a sail switch to a
connection at the air cleaner and then to a power connection at the furnace. Do I need the power cord from a new unit or can splice and tie in the power sources as I now have? Thank you, Best regards, Fred
A: You do not need the power cord if the air cleaner is connected in series with the sail switch and power source. You can splice the wire or remove it if not needed if you can use your current wires.
