How hard is it to install an Aprilaire humidifier myself (either bypass type such as 560A/568 or forced air 760A/768)? I'm comfortable with electrical & plumbing work.
It looks like all I need to do is connect a water inlet, drain, 24V, relay from the blower motor, and cut holes in the return air and forced air plenums. Is that it? Are there pitfalls I'm not aware of?
