Mounting
Vertical units can be mounted on the floor or a concrete
pad, typically in a mechanical closet or other area en-
closed from the space to promote a quieter occupied
environment..
Horizontal units must be hung from the ceiling. Mount-
ing brackets, rubber grommets, bolts and washers are shipped in place on the unit. The mounting brackets
are designed to accept up to a 3/8-inch threaded rod
(by others). A flat washer and two nuts (both by others)
should be used to mount the unit on the ceiling at-
tached threaded rods. When installed, the unit should
be slightly pitched toward the condensate drain con-
nection.
