included in the wall sleeve extension as shown in
the illustrations below.

When installing a new chassis into an existing wall
sleeve with an extension, it will be necessary to relocate
the two air splitters to match the dimensions shown in

Louvers
Two styles of exterior louvers are available.
The standard ush stamped louver is a one-piece
stamped aluminum type that is nished natural and
clear anodized. Attractive, rugged architectural
louvers are extruded aluminum and are nished
natural and clear anodized (optional colors are also
available).
Louvers by others are acceptable as long as they
meet factory specications. They must have a
minimum free area of 70% or a pressure drop not
exceeding .05 in. w.g. at 300 fpm face velocity, and
a blade design that will not cause recirculation of
condenser air.
