Anchoring
Figures 3 through 5 on the following pages illustrate typical wall
sleeve installations. After the wall sleeve has been set in place
anchor it in the opening as shown in Figure 2. It is recommended
that rubber isolation washers be used with the fasteners to minimize sound transmission from the equipment to the wall, at the
point of contact.

(see Figure 3).
The recommended procedure for installing units in panel wall
and thin wall construction is as follows:
3. Level wall sleeve in all directions and anchor with appropriate
