I have successfully installed one humidifier on the one furnace and now onto the next one. Second furnace threw me a surprise, no where to install it on the supply side. Return duct is open but where do i install the bypass duct and humidistat? There is an area in between furnace and coil i could attach the bypass duct but unsure to do that and only other way would to run it up to the supply trunk out. Would I install the humidistat above the humidifier on the return side or? again
By the way its a bypass Aprilair 600M on a Trane XV95
For particular installation project that throw some curveballs, I would suggest possibly calling a professional out to at least survey the situation. It may be worth the 100 bucks to pick the professional HVAC person to see what they would do for installation.
