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.
