AFDH-SVN01A-EN 19
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 lbs.
– 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 ® part number for a proper 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.
