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 to horizontal ducted 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 open-
ings and all ductwork should be secured to the flanges. Insulate
and weatherproof all external ductwork, joints, and roof or build-
ing openings with counter flashing and mastic in accordance with
applicable codes.
Do not cover or obscure visibility to the unit’s informative data
plate when insulating horizontal ductwork.
