INSTALLING PANEL
Install the louvered panels as follows:
1. Position the panel almost parallel with the unit as
illustrated in figure 13, detail D with the screw side as
close to the unit as possible.
2. With a continuous motion slightly rotate and guide the
lip of top tab inward as illustrated in figure 12, details
A and C; then upward into the top slot of the hinge
corner post.
3. Rotate panel to vertical to fully engage all tabs.
4. Holding the panel’s hinged side firmly in place, close
the right−hand side of the panel, aligning the screw
holes.
5. When panel is correctly positioned and aligned, insert
the screws and tighten.
STABILIZING UNIT ON UNEVEN SURFACES
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.
With unit positioned at installation site, remove two side
louvered panels to expose the unit base pan.
Install the
brackets as illustrated in figure 14 using conventional
practices; replace the panels after installation is complete.
IMPORTANT
Unit Stabilizer Bracket Use (field−provided):
Always use stabilizers when unit is raised above the
factory height. (Elevated units could become unsta-
ble 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 is not being
installed then proceed to
Brazing Connections
on page 10.
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.
REFRIGERANT LINE SET
Field refrigerant piping consists of liquid and suction lines
from the outdoor unit (braze connections) to the indoor unit
coil (flare or sweat connections). Use Lennox L15 (sweat,
non−flare) series line set, or use field−fabricated refrigerant
lines as listed in table 2.
NOTE − When installing refrigerant lines longer than 50
feet, see the Lennox Refrigerant Piping Design and
Fabrication Guidelines, or contact Lennox Technical
Support Product Applications for assistance. To obtain the
correct information from Lennox, be sure to communicate
the following points:
