LOUVERED PANEL REMOVAL

Remove the louvered panels as follows:

1.

Remove two screws, allowing the panel to swing open slight­
ly.

2.

Hold the panel firmly throughout this procedure. Rotate bot­
tom corner of panel away from hinged corner post until lower
three tabs clear the slots as illustrated in 

detail B.

3.

Move panel down until lip of upper tab clears the top slot in
corner post as illustrated in 

detail A

.

LOUVERED PANEL INSTALLATION

Position the panel almost parallel with the unit as illustrated in

detail D 

with the screw side as close to the unit as possible.

Then, in a continuous motion:

1. Slightly rotate and guide the lip of top tab inward as illus­

trated in 

detail A

 and 

C

; then upward into the top slot

of the hinge corner post.

2. Rotate panel to vertical to fully engage all tabs.

3. Holding the panel's hinged side firmly in place, close the

right-hand side of the panel, aligning the screw holes.

4. When panel is correctly positioned and aligned, insert

the screws and tighten

.

IMPORTANT! DO NOT ALLOW PANELS TO HANG ON UNIT BY TOP TAB. TAB IS FOR
ALIGNMENT AND NOT DESIGNED TO SUPPORT WEIGHT OF PANEL.

PANEL SHOWN SLIGHTLY ROTATED TO ALLOW TOP TAB TO EXIT (OR
ENTER) TOP SLOT FOR REMOVING (OR INSTALLING) PANEL.

MAINTAIN MINIMUM PANEL ANGLE (AS CLOSE TO PARALLEL WITH THE UNIT
AS POSSIBLE) WHILE INSTALLING PANEL.

New or Replacement Line Set

REFRIGERANT LINE SET

This section provides information on installation or
replacement of existing line set. If new or replacement line
set is not being installed then proceed to 

Brazing

Connections 

on page 14.

IMPORTANT

Lennox highly recommends changing line set when
converting the existing system from HCFC-22 to
HFC-410A

.

 If that is not possible and the line set is the

proper size as referenced in table 2, use the procedure
outlined under Flushing the System on page 13.

If refrigerant lines are routed through a wall, then 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. See figure 6 for recommended
installation practices. Also, consider the following when
placing and installing a high-efficiency outdoor unit.

Liquid lines that meter the refrigerant, such as RFC1 liquid
lines, must not be used in this application. Existing line set
of proper size as listed in table 2 may be reused. If system
was previously charged with HCFC-22 refrigerant, then
existing line set must be flushed (see 

Flushing

 on page

17).
