NOTE: Follow all wall system manufacturer installation instructions. For sunrooms and modular buildings, adhere to their installation instructions for
supporting and sealing sleeve to their frames. All wall and window/wall installations must provide for proper drainage. In applications where the
drain holes on the PTAC wall sleeve are not exposed beyond the wall an internal drain system is recommended. It is the installer's responsibility to
ensure there is adequate drainage for the PTAC unit.
