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.

Wall sleeveextensions--maximum of 3 may be used.

Run a bead of silicone sealant along the bottom mating

surfaces of the wall sleeve and the wall sleeve extension. Run

this bead at least 3 in. (7.6 cm) up the side seams.
