2.4 Horizontal Installation
2.4.1 Front Doors
The hanging brackets are supplied loose with the
necessary hardware to install them. They are not
shipped assembled due to the variability of installation
access on job sites.
Each hanging bracket is composed of two pieces: an
inner component and an outer component. The units
are designed to have four sets of brackets to support
the unit.
Note Depending on the ducted opening location
selected during the design phase, the location of
the brackets will vary. Please consult your submittal
drawings for specific locations.

the ¼" bolt. 32 - ¼" bolts, 32 - ¼" lock nut, 32 - ¼"
washers and 64 - ¼" washers have been provided
with the unit.
3. Assemble the hanging bracket by aligning the 8
holes of the outer bracket through the unit and
with the inner bracket. Note: the inner component
should be oriented so that its flange is pointing to
the ceiling, and the outer bracket has the single
hole pointing to the ceiling.
4. Install the 8 bolts. Caution - Do not over tighten
and crush the panel.
5. Install 4 tek-screws in the flange portion of the
inner bracket and secure it to the top casing of the
unit.
6. Install 4 tek-screws in the lower flange of the outer
bracket to secure it to the bottom frame of the unit.
7. Repeat steps 1 through 6 for the remainder of the
brackets.
