NOTES:

1. Unit sleeve and sleeve extension (ﬁeld fabricated) should

be connected before installing in wall opening.

2. Sleeve extension is water bearing. It must be watertight

when installed against unit sleeve. Use quality grade seal-

ant on all butting ﬂanges. Attach both sections with bolts

and nuts or self-tapping screws installed from unit sleeve

to extension. Cut drain slots in front and rear ﬂanges of

extension to line up with drain openings in unit sleeve.

3. Install 2 center baffles inside sleeve extension to pre-

vent recirculation of outdoor air circuit.

4. Leave

⁄

-in. roomside projection of extension and

-in.

outdoor projection of sleeve. This allows for unit casing

clearance to ﬁnished wall plus ample edging to apply

weather sealant between unit sleeve/extension assem-

bly and wall opening.

5. Paint sleeve extension and seal corner and lap joints;

clear all drain holes of excess sealant, paint, etc., to per-

mit free drainage.

6. Install quality ﬂashing under unit sleeve and extension

using quality sealant between ﬂashing and wall.

7. Install unit casing/extension assembly following stand-

ard practices. Seal assembly to wall on all 4 sides, in-

doors and outdoors.

8. Make provision for a condensate drain extension tube

for routing excess condensate from the wall sleeve through

the sleeve extension to the building exterior.

9. Attach grille to the outside of the sleeve extension

(using ﬁeld-supplied fasteners).

10. Seal any gaps between grille and sleeve extension on

all sides.
