WALLSLEEVEEXTENSION
INSTAUATION INSTRUCTIONS
The PTAC/PTHP is intended for mounting through an exterior
wall. If the wall is thicker than 13 in. (33 cm), an extension to
the wall sleeve must be used. The PTAC/PTHP should be
installed level or pitched slightly to the outside. The exterior
of the sleeve must be caulked at the building interface.
Unpack and dispose of packaging materials.
NOTE: Do not remove weatherboard and center support from
wall sleeve until ready to install chassis and outdoor grille.
Construct and install flashing into wall cutout, as shown.

Run a bead of silicone sealant along the perimeter of the
flashing.
Attach wall sleeve extension to the wall sleeve using 4 sheet
metal screws (provided).
NOTE: Do not overtighten the screws. The wall sleeve
extension is aluminum, and overtightening will strip out the
holes.
