INSTALLATION—CONTINUED
Field-Installation of Cooling Coil Cabinet and Downturn Plenum
⚠ WARNING ⚠
Do NOT install the cooling coil cabinet before lifting the packaged blower/furnace system into
position. Lift the cooling coil cabinet separately. Do NOT install the cooling coil cabinet while the
furnace is in operation.
NOTES:
• If the cabinet is being installed on an indoor model SSCBL, consult the factory regarding
installation. If suspending the cabinet, consult the factory.
• The optional cooling coil cabinet is shipped separately for field-installation. The cabinet includes
either a chilled water or a refrigerant (DX) air conditioning coil. Cabinets alone have horizontal
discharge but may have an attached downturn plenum for vertical discharge.
• The total length of an indoor system with a cooling coil cabinet depends on how the system is
installed. If the blower/furnace is suspended, a special curb cap and a field-installed transition
duct are required. Contact your Sales Representative to receive specific information. If an indoor
system is mounted, add the cabinet length to the blower/furnace length listed in Table 2 or Table 3 .
• Optional two-position discharge dampers in option AU12 or AU14 fit in the discharge air opening.
The damper motor fits inside the downturn cabinet.
• If the downturn plenum is equipped with discharge dampers, field wiring including drilling holes
and running wires is required. Cooling coil cabinet dimensions are listed in Table 12 and shown
in Figure 7 .
