Step 7 — Convert to Horizontal and Connect
Ductwork (when required)
Unit is shipped in the vertical duct configuration. Unit without
factory-installed economizer or return-air smoke detector op-
tion may be field-converted to horizontal ducted configuration.
To convert to horizontal configuration, remove screws from
side duct opening covers (see Fig. 7) and remove covers. Use
the screws to install the covers on vertical duct openings with
the insulation-side down. The panels must be inserted into the
notches on the basepan to properly seal. The notches are cov-
ered by the tape used to secure the insulation to the basepan
and are not easily seen. See Fig. 8 for position of the notches in
the basepan. Seals around duct openings must be tight. Secure
with screws as shown in Fig. 9. Cover seams with foil duct
tape.
Field-supplied flanges should be attached to horizontal duct
openings and all ductwork should be secured to the flanges. In-
sulate and weatherproof all external ductwork, joints, and roof
or building openings with counter flashing and mastic in accor-
dance with applicable codes.
Do not cover or obscure visibility to the unit's informative data
plate when insulating horizontal ductwork.
