Complete Model Number
The complete unit model number consists of
a base model number followed by and series
of individual module numbers. In the
individual module model number, the three
numbers after the three letter Module ID
indicate the position of the module in final
air handler assembly, increasing in value
from the return/outside air section to the
discharge air section. In the above example,
the cooling coil module, CLA-103-A-00-
CNCA0-00000-0-0, would be the third
module in the air handler.
