Installing With a Wall Sleeve
FIGURE 6-1 HW/HWC Installation
Refer to the installation instructions packed with the wall sleeve and
Figure 6-1 for guidance in assembly and mounting using a wall sleeve.
See also the Accessories section beginning on page 7-3 for further
details on wall sleeve installations.
Refer to page 6-6 for information concerning additional support under the
HW/HWC unit.
Make sure the gaskets attached to the sleeve are not damaged.
Seal the space between the wall sleeve and the building opening with
non-hardening caulking compound. The seal must be weathertight to
prevent entrance of moisture and water into the building.
Assure that the unit is completely seated against the gaskets on the wall
sleeve.
The sleeve is not intended as the sole support for the
unit. Additional support must be provided near the
return opening on the unit for adequate support. The
use of vibration isolation material between the unit and
the support is recommended.
