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 and remove covers. Using the same screws, install
covers on vertical duct openings with the insulation−side
down. Seals around duct openings must be tight. See
Fig. 10.
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.
