11.5 Filter Section Installation - Horizontal Air
Handlers
11.5.1 Filter Section Installation (2005)
For installation directly onto the inlet of the air
handler, remove the hardware on the inlet surface of
the air handler that would prevent the filter section
from being mated to the inlet of the air handler. Use
the provided shims (one bottom and two sides) to
reduce the size of the gap between the air handler
and the filter section. Re-install the hardware (that
was removed) through the filter section and the
shims to mate the air handler to the filter section.
Hardware must be torqued to recommended
specifications on Page 9, Table 1. Caulk (provided by
others) the sides, roof and bottom seams between
the filter section and air handler. Apply 3" zip tape
(provided by others) over the roof seam. Install the
filters in proper orientation (See Page 130, Section
20.6) and attach the filter access door. Secure filter
access door in the closed position.
11.5.2 Filter Section Installation (2010 - 2030)
For installation directly onto the inlet of the air
handler, foam tape (provided by others) must be
applied to the air handler sides and bottom. To place
the filter section, the top flange of the filter section will
slide up under the top panel (drip edge) of the air
handler. Refer to Page 43, Figure 23. All hardware in
this top panel drip edge will need to be removed prior
to placing the filter section on the air handler. Attach
the sides of the filter section to the factory installed
riv-nuts on the inlet of the air handler w
ith the
supplied hardware. Re-install the hardware from the
top panel of the air handler through the top panel and
top flange of the filter section. Additional TEK screws
may be used along the bottom flange of the filter
section to seal the bottom seam. Caulk (provided by
others) the side and bottom seams between the filter
section and air handler. If the filter section was
installed prior to completing the filter section
assembly, return to the filter section assembly
instructions to complete the assembly. See Page 33,
Figure 11.2.5 for Models 2010 and 2010B or Page 39,
Figure 11.3.6 for Models 2020 and 2030.

11.6.1 Filter Section Installation (2005)
For installation directly onto the inlet of the air
handler, remove the hardware on the inlet surface of
the air handler that would prevent the filter section
from being mated to the inlet of the air handler. Use
the provided shims (one bottom and two sides) to
reduce the size of the gap between the air handler
and the filter section. Re-install the hardware (that
was removed) through the filter section and the
shims to mate the air handler to the filter section.
Caulk (provided by others) the sides, roof and bottom
seams between the filter section and air handler.
Install the filters in proper orientation (See Page 130,
Section 20.6) and attach the filter access door.
Secure filter access door in the closed position.
11.6.2 Filter Section Installation (2010 - 2030)
To install a filter section on an u
pright air handler that
is stand mounted, the filter section must be installed
in the stand prior to placing the air handler (See Page
22, Section 8 for proper stand mounting). Place the
filter section so that the outward flange is on the top
side. Set the filter section into the stand. Place ½"
foam tape (supplied by others) along the perimeter of
the top of the flange. Place the air handler in the
stand per the stand mounting instructions.
