* C and D are roof opening dimensions.
** Field installed means that the cooling coil cabinet with or without the downturn is factory assembled and shipped
separately. The roof curb is sized to accommodate the complete length of the system. The shipped-separate cooling
coil cabinet with or without a downturn must be lifted to the roof separately from the packaged system, set on the roof
curb, and attached to the furnace section (see instructions in Paragraph 6.3.6).

IMPORTANT: Top surface of the
roof curb MUST be sealed.
* Illustration is shown with an Option AQ5 or AQ8
downturn plenum. The system can have a variety
of configurations which affect installation.
• If the system does not have a downturn plenum,
the discharge is horizontal.
• Downturn plenum Options AQ5 and AQ8 are
factory installed to be lifted to the roof and set on
the roof curb as part of the packaged system.
• If the system has an Option AU2 or AU3 cooling
coil cabinet, the discharge is horizontal. If
the system has an AU11, AU12, AU13, AU14
cooling coil cabinet, there is a downturn plenum
with vertical discharge. Options AU2, AU3,
AU11, AU12, AU13, and AU14 are not factory
installed. Options AU2, AU3, AU11, AU12,
AU13, and AU14 must be lifted to the roof
separately from the packaged system, set on
the roof curb, and attached to the furnace.
IMPORTANT: Area enclosed by the roof curb must comply with clearance to
combustible materials. If roof is constructed of combustible materials, area
within curb must be either ventilated, left open, or covered with non-combus-
tible material which has an "R" value of at least 5.0. If area within curb is left
open, higher radiated sound levels may result.
Bottom Duct Connections - The blower section and optional downturn plenum have
duct flanges for connection to return air and supply air ducts. Duct opening sizes and
curb spacing shown in FIGURE 9D are for currently manufactured curbs that are avail-
able from the system manufacturer.
