DIMENSION DRAWINGS AND INSTALLATION

DATA — NEW CONSTRUCTION (cont)

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 sealant 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 prevent recir-

culation of outdoor air circuit. These baffles should make a

tight seal between the outdoor coil and the outdoor grille.

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 assembly and wall

opening.

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

all drain holes of excess sealant, paint, etc., to permit 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 standard

practices. Seal assembly to wall on all 4 sides, indoors and

outdoors.

8. Make provision for a condensate drain extension tube for rout-

ing 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.
