Warnings and Cautions
Protecting the Environment
World environmental scientists have concluded, based on the best currently available
evidence,thatozoneinourupperatmosphereisbeingreducedduetothereleaseof CFC
(chlorofluorocarbon) fully halogenated compounds.
Trane urges that all HVAC servicers working on Trane equipment, or any manufacturer’s
products, make every effort to eliminate, if possible, or vigorously reduce the emission
of CFC, HCFC (halocarbon that contains fluorine, chlorine, carbon, and hydrogen), and
HFC (halocarbon that contains only fluorine, carbon, and hydrogen) refrigerants to the
atmosphereresultingfrominstallation,operation,routinemaintenance,ormajorservice
on this equipment. Always act in a responsible manner to conserve refrigerants for
continued use even when acceptable alternatives are available.
Refrigerant used in any type of air-conditioning or refrigerating equipment should be
recovered for reuse, recovered and/or recycled for reuse, reprocessed (reclaimed), or
properly destroyed, whenever it is removed from equipment. Never release it to the
atmosphere!

Warnings and Cautions
 WARNING
Equipment Damage From Ultraviolet (UV) Lights!
Trane does not recommend field-installation of ultraviolet lights in its air handling
equipment for the intended purpose of improving indoor air quality. High intensity
C-band ultraviolet light is known to severely damage polymer (plastic) materials and
poses a personal safety risk to anyone exposed to the light without proper personal
protective equipment (could cause damage to eyes and skin). Polymer materials
commonly found in HVAC equipment that may be susceptible include insulation on
electrical wiring, fan belts, thermal insulation, various fasteners and bushings.
Degradation of these materials can result in serious damage to the equipment.
Trane accepts no responsibility for the performance or operation of our air handling
equipment in which ultraviolet devices were installed outside of the Trane factory.
Ultraviolet (UV) Germicidal Irradiation Lights (optional)
The United States Environmental Protection Agency (EPA) believes that molds and
bacteria inside buildings have the potential to cause health problems in sensitive
individuals. If specified, Trane provides ultraviolet lights (UV-C) as a factory-engineered
and installed option in select commercial air handling products for the purpose of
reducing microbiological growth (mold and bacteria) within the equipment. When
factory provided, polymer materials that are susceptible to deterioration by the UV-C
light will be substituted or shielded from direct exposure to the light. In addition, UV-C
radiation can damage human tissue, namely eyes and skin. To reduce the potential for
inadvertent exposure to the lights by operating and maintenance personnel, electrical
interlocks that automatically disconnect power to the lights are providedat all unit entry
points to equipment where lights are located.

CLCH-SVX06A-EN • T-Series Climate Changer Air Handler 7
General Information
Operating Environment
The T-Series Climate Changer air handler is a central station outdoor air handler. When
considering the placement of the T-Series air handler, it is important to consider the
operatingenvironment.The acceptableambient temperaturerangeforunit operationis
-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 94 for more information.

General Information
Factory-Mounted Controls
The T-Series air handler is 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.
Smallitemsthatcannotbefactory-mounted,suchasspacetemperaturesensors,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 starters or 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
3 ampsforunitsizes3to57and5 ampsforunitsizes66to100.Adedicated15-ampcircuit
is recommended.
Factory-mounted control systems ordered with factory-mounted starters or VFDs are
suppliedwithlineto24 Vaccontroltransformers.Noadditionalpowerwiringisrequired.
Pre-Packaged Solutions for Controls
If the T-Series airhandler has been selectedusing 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.
For a more in-depth understanding of controls, refer to the following manuals:
• For factory-configured AH540/AH541 controllers
–CNT-SVX05B-EN
• For programmable MP580 controllers
–CNT-SVP01A-EN
• For hardware installation
–CNT-SVN01A-EN
• For Trane TR1 Drives (from Danfoss)

Wiring
WARNING
Grounding Required!
All field-installed wiring must be completed by qualified personnel. All field-installed
wiring must comply with NEC and applicable local codes. Failure to follow these
instructions could result in death or serious injuries.
Entrances are provided for field-installation of high and low voltage wiring through a
pipe/nippleconnectioninthebaseoftheunit.Thelow-andhigh-voltageconnectionsare

installation, consider overall unit serviceability and accessibility before mounting,
running wires (power), making penetrations, or mounting any components to the
cabinet.
Wiring to T-Series units must be provided by the installer and must comply with all
nationalandlocalcodes.Thefanmotornameplateincludesawiringdiagram.Ifthereare
any questions concerning the wiring of the motor, write down the information on the
motor nameplate and contact your local Trane sales office.

Pre-Installation Requirements
The T-Series air handler typically ships as a complete air handler, but if shipping splits
are required, it can ship in individual sections, or in section sub-assemblies. Unit sizes
3 to 100 have an integral base rail.
The specifications provided in Table 1 indicate the maximum values for a single-piece
shipment. If either the maximum weight or maximum length is exceeded, the T-Series
unit will ship in multiple pieces.
Note: These limits are based on a four-point lift.
Inspection Checklist
Upon receipt of the air-handling unit, prior to unloading, visually check the components
foranydamagethatmayhaveoccurredduringshipment.Conductathoroughinspection
immediately before accepting the shipment.
Note: Delivery cannot be refused. Trane is not responsible for shipping damage.
• Check all access doors to confirm the latches and hinges are not damaged.
• Inspect the interior of each section for any internal damage.
• Concealed damage must be reported within 15 days of receipt.
• Inspect the coils for damage to the fin surface and/or coil connections.
• If the unit was ordered with factory-mounted controls, locate all sensors.
• Items that cannot be factory-mounted should ship inside the control enclosures, or
should be packaged inside the fan or mixing box section.
• Check all control devices attached to the unit exterior and confirm they are not
damaged.
• Manually rotate the fan wheel to ensure free movement of the shaft, bearings, and
drive.
• Inspect the fan housing for any foreign objects.
• Iftheunitshippedinsub-assemblies,locatetheassemblyhardware,whichshouldbe
