Downflow Air Conditioning Coil Cabinet
The Cooling Coil Cabinet can be used in place of the combustible floor
base for downflow installations on combustible materials. The furnace
should be installed with the cooling coil cabinet specifically intended for
downflow applications. The cooling coil cabinet must be secured to the
floor. A supply air duct plenum is installed through the opening pro-
vided. The supply air duct is then secured to the duct system with
screws and sealed to prevent leaks. If a matching cooling coil is used, it
may be placed directly on the furnace outlet using the accessory transi-
tion kit and sealed to prevent leakage. The transition kit must be used to
secure the cooling coil cabinet to the furnace casing when installed in a
downflow configuration.

These kits are required in downflow application when using G*F* series
coils. These kits are not required with MC/FC series coils, but please
ensurethat the coil and furnace are sucured and that there are noair
leaks.

IMPORTANT: On all installations without a coil, a removable access
panel is recommended in the outlet duct such that smoke or reflected
light would be observable inside the casing to indicate the presence of
leaks in the heat exchanger. This access cover shall be attached in
such a manner as to prevent leaks.

Horizontal Installations With a Cooling Coil Cabinet
The furnace should be installed with the cooling coil cabinet specifically
intended for horizontal applications. If a matching cooling coil is used, it
may be placed directly on the supply air side of the furnace and sealed
to prevent leakage. A warm air duct plenum with 1" (2.54 cm) is
installed through the opening provided. The supply air duct system is
connected to the warm air plenum and sealed to prevent leaks.

Attach the supply plenum to the air conditioning coil cabinet outlet duct
flanges through the use of S cleat material when a metal plenum is
used. The use of an approved flexible duct connector is recommended
on all installations. The connection to the furnace, air conditioning coil
cabinet and the supply plenum should be sealed to prevent air leakage.

The sheet metal plenum should be crosshatched to eliminate any pop-
ping of the sheet metal when the indoor fan is energized. The minimum
plenum height is 12" (30.5 cm). If the plenum is shorter than 12" (30.5
cm) the turbulent air flow may cause the limit controls not to operate as
designed, or the limit controls may not operate at all. Also the plastic
drain pan in the under the air conditioning coil can overheat and melt

Horizontal Installations Without a Cooling Coil Cabinet
When installing this appliance, the furnace must be installed so as to
create a closed duct system, the supply duct system must be con-
nected to the furnace outlet and the supply duct system must terminate
outside the space containing the furnace. When replacing an existing
furnace, if the existing plenum is not the same size as the new furnace
then the existing plenum must be removed and a new plenum installed
that is the proper size for the new furnace.
