New construction. The unit sits in a pan and has a kill switch if the water gets to high. Builder said normally they install a pipe to drain by a window, but since no window was near by they didn't install one. He said it shouldn't be a problem since the unit sits in what is considered conditioned space (attic insulated with spray foam). I thought condensate removal to the outside was a standard thing. Is it not necessarily required? The house already passed inspection.
Code requires it to either drain out, or have a shut off device if it doesn't have a drain. So it is in compliance since it has a shut off device.
Is that for primary condensate removal or for auxiliary / backup? I was under the impression condenstate had to be removed as part of normal operation, but there were options for auxillary / overflow that spilled into the catch pan. I can't imagine code would allow the sealed, unventilated attic space to be used as evap space for water by design.
I asked the builder for clarification if the "no drain" part was in reference to primary condensate removal or backup / overflow. Thx for the response.
what the contractor is talking about is the equipment malfunction overflow pan needs no drain if there is a safety switch connected to the equipment.
if you look, the a/c coil will indeed have a drain and it will either run along the freon lines, and drain out there, or it will connect to a trapped soil line. if there is no drain connected to the a/c coil, then there is CERTAINLY going to be a problem!!!!
