INSTALLATION

1. Unpack accessory from carton. Check to be sure contents
are not damaged or missing. See Table 1.

2. Select mounting location on the wall. The location must
allow for use of wall studs for mounting security. Check

local building codes and building construction to ensure
that there is adequate wall strength to support the mounted

unit. The location must also allow for condensate drainage
from the unit. Be sure this drainage does not cause a

problem for the area beneath the unit.

IMPORTANT: Ensure that the unit will be mounted at least 6 in.
from the wall for proper airflow. Also ensure that there will be at

least 6 in. of airflow clearance on the coil end and 18 in. on the
compressor end for service access.
IMPORTANT: Do not drill new holes in the bracket assembly in

order to move the unit closer to the wall.

3. Use the enclosed long bracket sections as a template for
marking the mounting kit location on the wall. Both long

bracket sections must line up with the middle and coil end
mounting feet of the unit. See Fig. 1.
