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
option may be field-converted
configuration. To convert to horizontal configuration, remove
screws from side duct opening covers (see Fig. 10) 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 covered by the tape used to secure the insulation to
the basepan and are not easily seen. See Fig. 11 for position of
the notches in the basepan. Seals around duct openings must be
tight. Secure with screws as shown in Fig. 12. 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.
