For an air handler without a filter section:On the inlet of the air handler, install horizontal and upright
mounts. The mounts will be installed via angles open towards the outside of the air handler.
For an air handler with a filter section: First, attach the filter section to the air handler. Then, bolt the
inlet hood horizontal and upright mounts to the inlet of the filter section with the angles opening towards
the inside of the filter section.
Upright mounts (P/N 13505090) are attached with five 3/8-16 bolts (P/N 20517) and flat washers
(P/N 20515) each; the receiving riv-nut (P/N 91120106) will be factory installed on the air handler or filter
section. Horizontal mounts (P/N 13505091) are attached using five TEK self-tapping screws (P/N 13404).
Prior to installing the mounts, seal the gap between the mating surfaces of the air handler/filter section
and the mounts with the provided foam tape (P/N 92700017).
When installing the top horizontal mount directly to the air handler without a filter section, foam tape
should NOT be used. In this case, the hardware on the lip of the air handler roof panel should be removed,
the mount slid under the lip and hardware re-installed. Foam tape to be used on remaining three sides.
To install inlet hood on an exterior wall, drill holes ev
ery 8" (20.3 cm) in the flanges of the inlet hood and
mount with lag bolts (provided by others).
