Chapter 1.0 Introduction
This section provides a brief introduction to the Service Manual including the Application, Purpose,
Organization, Document Conventions used, Safety Information, and the Danfoss LLC Quality Policy.
1.1 Application
As of May 6, 2019, the product nomenclature changed. "Figure 1-1 Old to New Type Code" maps the
old structure of the Type code to the new structure. Additionally, the “Series” indicators not have an
additional character in order to differentiate the standard compressors from high-lift compressors.
Unless the compressor is a high-lift design, an “S” will be added (e.g., TTS350). A high lift compressor
will have an “H” in the Series designation (e.g., TTH375). Throughout this manual, it shall be assumed
that if a series designation contains neither an "S" or "H" (e.g., TT350) that it is not a high-lift design.
Refer to "Figure 1-2 New Type Code" on page 16 for a complete description in the new design.
