retrofit and are actually compatible with an AFDH retrofit despite their root hardware part
number.
ii. If either (or both) these part numbers are lower that the software part numbers listed in
Table 1, the module or modules cannot be used with an AFDH drive. Purchase the
appropriate replacement modules through service parts.

Equipment room ambient temperature considerations
An air-conditioned equipment room is not a prerequisite for the installation and operation of an
AFDH retrofit drive package.
However, be advised that all models of the AFDH air-cooled drives are not suitable for installation
into equipment rooms where the ambient temperature conditions are expected to exceed either
95°F for a continuous 24-hour period, or where the potential maximum ambient temperatures can
exceed 104°F.
If the ambient temperatures exceed either of these conditions, the potential exists to trigger a drive
shut down from an over temperature fault - effectively disabling the chiller until the drive
temperature drops to the factory set, non-adjustable, safe temperature level that will allow the
drive to be restarted.
If the ambient temperatures routinely exceeds either of these conditions, the overall service life of
the drive may be compromised.
Chiller upgrades
• The chiller condenser loop setpoint should be set to 72°F to fully exploit the energy savings
possible with a retrofit AFDH drive.
• In some climates and applications, it may be beneficial to set the condenser loop setpoint even
lower, to 65°F.
Important: Under such low condenser water conditions, use of an oil recovery system is
recommended. These systems are found on all Trane chillers built since 1985. Refer
to general service bulletins CTV-SB-26 and CTV-SB-68 for upgrade information.
