Installing whole house humidifier, replacing my old Honeywell with Aprilaire

My Humidifier was leaking and not really working properly anyway as the humidity in my house had dropped a lot this year, so I decided to replace it myself. It actually wasn't that hard. just follow some instructions and away you go.
This is a huge help in my house.
