The following information is
provided on the unit nameplate.
1. Serial Number
The unit serial number provides the
specific chiller identity. Always
provide this serial number when
calling for service or during parts
identification..
2. Service Model Number
The service model represents the unit
as built for service purposes . It
identifies the selections of variable
unit features required when ordering
replacements parts or requesting
service.
Note: Unit-mounted starters are
identified by a separate number
found on the starter.
3. Product Coding Block
The CVHE, CVHF and CVHG models
are defined and built using the
product definition and selection
(PDS) system. This system describes
the product offerings in terms of a
product coding block which is made
up of feature categories and feature
codes. An example of a typical
product code block is given on this
page. The coding block precisely
identifies all characteristics of a unit.

About this manual
Operation and maintenance
information for models CVHE, CVHF
and CVHG are covered in this
manual. This includes both 50 and 60
Hz. CVHE, CVHF and CVHG
centrifugal chillers equipped with the
Tracer CH530 Chiller Controller
system. Please note that information
pertains to all three chiller types
unless differences exist in which
case the sections are broken down
by Chiller type as applicable and
discussed separately.
By carefully reviewing this
information and following the
instructions given, the owner or

and maintain a CVHE, CVHF or CVHG
unit.
If mechanical problems do occur,
however, contact a qualified service
organization to ensure proper
diagnosis and repair of the unit.
Note: The CH530 controller was first
applied to CVHE with Design
Sequence “3K”, and to CVHF with
Design Sequence “1W”.
