The furnace must also be equipped with an
automatic damper (See Figures 37 or 38,
NORDYNE p/n 901996 for furnaces without coil
cavity, or p/n 901083 with coil cavity) to prevent
cold air from being discharged up around the
heat exchanger. Cold air may cause conden-
sation inside the heat exchanger which can lead
to rust and early failure.
OPTIONAL ADD-ON AIR CONDITIONING
Ask your dealer or contractor about NORDYNE
add-on central air conditioning systems. There
is a split-system or package air conditioner
designed for your total comfort needs. Whether
split system or single package, an energy-
saving NORDYNE unit is available that has
been designed specifically for manufactured
housing applications and can best handle your
home comfort needs.
Listed and ARI Certified, all models are pro-
tected by the NORDYNE Air Conditioner Lim-
ited Warranty.
Platinum series units are self contained pack-
age units with compressor and cooling coils.
They are designed as a drop in system when
used with the AC ready M1.
Single package unit includes cooling coils, com-
pressor, and vertical discharge fan. This type
of unit connects with the existing home air duct
system (an optional close-off damper is re-
quired with the furnace).
Split system unit with vertical discharge for quiet
operation connects with NORDYNE cooling
coil furnace (optional coil cavity required with
“A” model furnaces).
