General Information
Operating Environment
The Performance Climate Changer™ air handler is a central station air handler for indoor
applications. When considering the placement of the air handler, it is important to consider the
operating environment. The acceptable ambient temperature range for unit operation is -40ºF to
140ºF (-40ºC to 60ºC).
For heating applications, a special motor may be required to withstand the higher temperatures.
Motors with Class B insulation are acceptable for ambient temperatures up to 104º F, while motors
with Class F insulation can withstand ambient temperatures to +140º F (60º C).
Note: Units with UL approval have a maximum ambient temperature requirement of 104ºF. The
customer should provide adequate freeze protection for the coils. See “Coil Winterization”
on page 126 for more information.
Unit Description
The Performance Climate Changer air handler is designed for a variety of controlled-air
applications. The basic unit consists of a fan, heating and/or cooling coils, filters, and dampers.
Trane air handlers ship as complete assemblies or in sub-assemblies if shipping splits are required.
Some assembly is required when the unit ships in subassemblies.
A wide variety of components is available for Trane air handlers, including numerous fan, coil, and
filter options, access sections, diffusers, discharge plenums, face-and-bypass sections, UL-
approved electric heat sections, humidifiers, mixing boxes, moisture eliminator sections, exhaust
dampers, controls, blenders and airflow monitoring stations.

Factory-Mounted Controls
Trane air handlers are available with a wide selection of factory-mounted controls, including
controllers, motor starters, and variable frequency drives (VFD).
Most control components are mounted inside the unit. Depending on the system configuration,
this may include damper actuators, dirty filter switches, averaging temperature sensors, and low
limit switches. VFDs, starters, controllers, control transformers, static pressure transducers, DC
power supplies, and customer interface relays will be in enclosures mounted on the inside of the
unit.
Small items that cannot be factory-mounted, such as space temperature sensors, outside air
temperature sensors, and humidity sensors, will ship inside the control enclosures, or packaged
and shipped inside the fan or mixing box section. Larger items are shipped inside the fan section.
Note: All control valves ship directly to the “ship-to address” from the vendor unless another
address is given on the Trane sales order.
