Step 7 — Convert to Horizontal and Connect
Ductwork (when required)
Unit is shipped in the vertical duct configuration. Unit with-
out factory-installed economizer or return-air smoke detector
option may be field-converted to horizontal ducted configura-
tion. To convert to horizontal configuration, remove screws
from side duct opening covers (see Fig. 7) and remove cov-
ers. Use the screws to install the covers on vertical duct open-
ings with the insulation-side down. The panels must be insert-
ed 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. 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.
Insulate and weatherproof all external ductwork, joints, and
roof or building 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.
