STABILIZING UNIT ON UNEVEN SURFACES
With unit positioned at installation site, remove two side
louvered panels to expose the unit base pan. Install the
brackets as illustrated in Figure 10 using conventional
practices. Replace the panels after installation is
complete.
TO MAINTAIN FULLY−ENGAGED TABS
To help stabilize an outdoor unit, some installations may
require strapping the unit to the pad using brackets and
anchors commonly available in the marketplace.
IMPORTANT
Unit Stabilizer Bracket Use (field−provided):
Always use stabilizers when unit is raised above the
factory height. (Elevated units could become
unstable in gusty wind conditions).
Stabilizers may be used on factory height units
when mounted on unstable an uneven surface.

New or Replacement Line Set

This section provides information on installation or
replacement of existing line set. If line set are not being
installed then proceed to Brazing Connections on page 11.
If refrigerant lines are routed through a wall, seal and
isolate the opening so vibration is not transmitted to the
building. Pay close attention to line set isolation during
installation of any HVAC system. When properly isolated
from building structures (walls, ceilings. floors), the
refrigerant lines will not create unnecessary vibration and
subsequent sounds. Also, consider the following when
placing and installing a high−efficiency air conditioner.
