Field Fabricating A Sleeve Extension

The Following points MUST be considered when designing a

wall sleeve extension.

1. Provision must be made to direct excess condensate from

the back of the wall sleeve to the outside of the build-

ing.

2. Air must be mounted to properly direct air

from the condenser.

3. Wall Sleeve Extension design must allow for the proper

mounting of the louvers.

4. Caulking of all potential sites where condensate or external

5. Seal strips must be attached to the outside edge of the

Extension Installation

Size wall sleeve extension to frame opening. Secure it to

the

wall sleeve before installing in the wall. Refer to Figure 4

for a

guide for fabrication of a condensate drip panel. Panel MUST

extend the full depth of the wall sleeve and the wall sleeve

extension. Pay particular care in sealing and caulking the panel

where it makes contact with the wall sleeve (see Figure 4 .)

After installation in the wall, secure with fasteners through the

sides. Seal around the sleeve extension with exterior caulking.

Using a good grade of silicone sealant, seal all exposed screw

heads. When installation is complete, outside louver may be

attached to wall sleeve extension.
