General Information
About this Manual
This manual describes proper
installation of Model CVHE, CVHF,
and CVHG 50 Hz and 60 Hz chillers
with the Tracer CH530 Controls
platform. See Figure 1 for an
illustration of a Centrifugal Chiller
with the Tracer CH530 Unit
Control Panel.
These chillers are equipped with
microcomputer-based control
systems whether standard cooling
or heat-recovery. A careful review of
this information along with the
submittal package provided for the
unit will assure that the chiller is
correctly installed.
Product Description Block
Trane 50 Hz and 60 Hz hermetic
CenTraVac units are defined by the
product definition and selection

the product description block which
appears on the unit nameplate. A
service model number which
represents the unit as-built is
provided on the unit nameplate,
along with a specific unit service
number. Both these are utilized
whenever parts or service are
required. An example is provided in
the unit operation and maintenance
manual (CVHE-SVU01A-EN).
