Model Number Description
Model Number Descriptions
All products are identified by a
multiple character model number that
precisely identifies a particular type of
unit. An explanation of the
alphanumeric identification code is
provided. Its use will enable the
owner/operator, installing
contractors, and service engineers to
define the operation, specific
components, and other options for
any specific unit.
When ordering replacement parts or
requesting service, be sure to refer to
the specific model number and serial
number printed on the unit
nameplate.
