General Information
Model Number Description
All products are identified by a multiple character model
number listed on the unit nameplate. An explanation of the
alphanumeric identification code is provided below. Its use
can define the unit's specific components, type of applica-
tion, i.e. CV or VAV, for a particular unit.
When ordering replacement parts or requesting service, be
sure to refer to the specific model number, serial number,
and DL number (if applicable) stamped on the unit name-
plate.
