General Information
Operating Environment
The Performance Climate Changer™ air handler is a
central station air handler for indoor and outdoor
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
"Routine Maintenance," p. 72
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.
Components
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, discharge plenums, UL-approved electric
heat sections, humidity management options, mixing
boxes, moisture eliminator sections, exhaust dampers,
controls, blenders and airflow monitoring stations.

available from your local Trane sales engineer:

Factory-Mounted Controls
Trane air handlers are available with a wide selection of
factory-mounted controls, including controllers, 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,
controllers, control transformers, static pressure
transducers, DC power supplies, and customer interface
relays will be in enclosures mounted on the inside of the
unit.
CLCH-SVX013B-EN
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.
All factory-mounted control systems (controls that are
factory-wired to a unit controller or termination strip)
ordered without variable-frequency drives (VFDs) are
provided with 120 to 24 Vac control transformers mounted
and wired in the auxiliary control panel. The customer
must provide 120 Vac control power, 50/60 Hz, typically
5 amps. A dedicated 15-amp circuit is recommended.

Factory-mounted control systems ordered with factory-
mounted VFDs are supplied with line to 24 Vac control
transformers. No additional power wiring is required.
Pre-Packaged Solutions for Controls
If the air handler has been selected using one of Trane's
pre-packaged solutions options for controls, there are a
number of resources available to aid in commissioning
and start-up of the unit. These resources include
commissioning sheets, graphics and technical application
notes. The technical application notes include the control
sequencing, Trane Graphic Programming (TGP) and Rover
set-up files for the specific unit selected. These resources
are available through your local Trane sales office.
