AFDH-SVN03H-EN 7
General Information
The step-by-step instructions outlined in this manual
describe the procedures required to successfully install an
AFDH Retrofit Air-Cooled Adaptive Frequency™ Drive
(AFD) package in place of an existing starter on a Trane
CVHE or CVHF model centrifugal chiller. This only applies
to chillers having either a UCP2™ or UCP2 FastPak™
Controller, a Tracer® CH531 Controller Retrofit, or a
Tracer® AdaptiView™ Controller.
D-Frame AFDH can be ordered in a unit mounted or remote
floor mounted cabinet configuration. Voltage options
include 460/480 volts, 380/400 volts, and 575/600 volts.
D-Frame size AFDH drive packages can be ordered in a
unit-mounted, stand-mounted, or remote floor-mounted
cabinet configuration. The D-Frame units can be equipped
with a drive having a maximum rating of 302 amps,
361 amps, or 443 amps for 460 V/480 V, and 242 amps,
344 amps, or 400 amps for 575 V/600 V.
Important: The unit-mounted versions of AFDH Retrofit
Air-Cooled Adaptive Frequency™ Drive
packages are not suitable for installation on
chillers having direct-mount starters. To
determine if a specific unit-mounted starter
is in fact a direct mount starter, please refer
to Figure 2, p. 9.
Notes:
• Prior to July 1994, early version UCP2™ and UCP2
FastPak™ controls did not have AFD compatible
software in their Chiller Modules or their Clear
Language Display Modules.Between July 1994 to June
1998 the first release of AFD compatible UCP2
hardware/software allowed a speed reduction down to
as low as 42 Hz. In June 1998, the second version
UCP2™ software release allowed speed reduction
down to 38 Hz, which resulted in slightly improved
energy savings. To determine if a specific UCP2™
control type is equipped with AFDH compatible
hardware and software, please refer to “UCP2
Compatibility with AFDH Drives,” p. 10.
• The factory installed Tracer® CH530 chiller controller
system will not support an AFDH Air-Cooled Adaptive
Frequency™ Drive. The controller system must first be
upgraded to Tracer® AdaptiView™ before an AFDH
retrofit package can be installed.
• The AFDH series of retrofit air-cooled Adaptive
Frequency™ Drive packages are only intended for
installation on existing Trane® chillers with CVHE or
CVHF model centrifugal compressors. Trane makes no
claim of suitability or performance regarding retrofit
AFDH drives on older Trane® centrifugal compressor
models or on chillers made by other manufacturers.
Although there may exist successful drive retrofits to
these units, users are cautioned that Trane has not
evaluated these installations. Accordingly, Trane
cannot provide assurances regarding performance,
reliability or suitability of retrofit AFDH installations to
other than Trane model CVHE and CVHF compressors.
