Pre-Installation
Requirements for Installation
Technicians
To properly install an AFDH Retrofit Adaptive Frequency
Drive package, the technician must have a good working
knowledge of the centrifugal chiller controller system
involved in the application. Training is highly
recommended before beginning this upgrade.

Tools Required

Normal tools are required to perform the work. An HVAC
service technician with a well stocked tool chest should
already have the majority of the normal tools needed for
this job.
In addition to the normally carried service tools and
hardware, the following is a partial list of specific field
supplied hardware and software components and special
tools that will also be required to perform the drive retrofit:
• The appropriate lifting device or devices (including
all necessary rigging hardware) with the capacity to
safely lift up to 1500 lb.
– Important! A spreader bar will be required if
the drive unit will be hoisted into position using
a single lifting device that is capable of making
only a single-point lift.
• A PC or laptop computer equipped with the correct
software tools for the chiller controller involved in
the application.
– TechView™ or KestrelView™service software
version 11.0 with service pack (SP) 3 or newer.
– Tracer TU service software version 2.01.020 or
newer.
Note: The most current CTV and CVR microprocessor
(MP) firmware files are included with the program
files for the TechView, KestrelView, and Tracer TU
service software tools.
• Type A to Type B USB cable to connect the computer
to a Tracer UC800 controller
• An RS-232 male DB9 to female DB9 pin to pin serial
cable connect the computer to a DynaView™
display
– Important: The cable must not be a "null-
modem" cable.
– Important: The cable must be less than 50 feet
in length.
– The Radio Shack
cable is 26-117B.
• South pole magnet screwdriver (TOL01343).

Miscellaneous Field-Provided
Material
Some field provided material will be required to perform
the drive retrofit. A partial list of material is provided here
to help the technician to plan ahead and to avoid material
shortages at the job site.
• Self-adhesive cable tie mounting bases and cable
ties.
– Used to help "clean up" wiring runs during the
installation process.
®
• Loctite 554 thread sealant for refrigerant
applications (Trane part number SEL00528).
– Used in applications where a pressure
transducer needs to be installed.
Recommended Rigging and
Lifting Procedures for AFDH Drive
Units
WARNING
Heavy Objects!
Failure to follow instructions below or properly lift unit
could result in unit dropping and possibly crushing
operator/technician which could result in death or
serious injury, and equipment or property-only damage.
Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of the
cables (chains or slings), hooks, and shackles used to
lift the unit must be capable of supporting the entire
weight of the unit. Lifting cables (chains or slings) may
not be of the same length. Adjust as necessary for even
unit lift.
WARNING
Improper Unit Lift!
Failure to properly lift unit could result in unit dropping
and possibly crushing operator/technician which could
result in death or serious injury, and equipment or
property-only damage. An AFDH cabinet assembly is
top heavy. Test lift unit approximately 24 inches to
verify proper center of gravity lift point. To avoid
dropping of unit, reposition lifting point if unit is not
level.
