    Sweet, one of the new collaboration units from Mitsu.
    Hoping it goes better then Trane/Samsung did.
    A bunch of the schools down here are doing similar things with water source VRF.

    Yup, that’s how the Trane-Sung units were. Peel off the Samsung logo and put a Trane one in its place. Except they didn’t do great things together.

    Looks nice. Have you had any problems with the white linesets leaking from formicary corrosion? I have read some have had problems and it seems sometimes the foam is acidic.
    Makes me leery of using it which is a shame because it looks so good.

    No. But, the tubing had a foul smell while purging N2. Almost like a carcinogen smell. Hope we don't have issues
