    April aire

    Model # 550

    I had it tied into the supply plenum....
    but now ....witht he cased coil.....no room.....So it will be placed on the Return plenum....
    Should I get the same results ?

    This April aire .....also has a 6" takeoff ...on the side....that would normally go to the return......

    I........... will probably have to cap that off......

    No... you don't want to cap it off, you have to pull heated air through the water panel.

    Here is a link to all of Aprilaire's Manuals:

    Humidifier...duct to supply

    I took a look at the manuals....

    .......... IF...I attach the Aprilaire..mod #550

    to the return plenu.....then off of the
    6" collar...
    take a 6" 90 26 g.

    bring a short piece of flex to the supply plenum....will this work

    The manuals ...did not really get into installation Options...

    Yeah that should work fine... all you have to do is pass air off the plenum through the water panel in order to make it work. You should also put a damper in your flex line off the plenum so you can close it off in the summertime and not recirculate your a/c back into the return drop.
