Unit Description

Trane T -Series Climate Changers® are Central
Station Air Handlers designed for a variety of air
handling applications. The basic unit consists of a
fan, heating and/or cooling coils, filters, and
dampers. See the sales catalog (CLCH-DS-9) for a
list of available options and components.

The fan is internally isolated. Fans available are
double-width, double-inlet Centrifugal types with
forward curved, backward inclined, or airfoil blade
type design; single-width, single-inlet Plug Fans or
Vane-Axial Q Fans
medium, and high pressure classes with or without
inlet guide vanes.

To insure fan stability, the unit ships with four (4) lock­down devices that prevent the fan from shifting
during shipment and installation. These spacers
must be removed prior to fan operation to assure
proper vibration isolation.

The units are available with factory-mounted controls
for stand-alone operation or operation with a
complete building automation system. This includes
factory-mounted starters, DDC controllers, and end
devices.

Operating Environment

The T-Series Climate Changer (TSC) is an outdoor
air handler. When considering the placement of the
TSC it is important to consider the operating
environment. The acceptable ambient temperature
range for unit operation is -40° to +140°F (-40°C to
60°C).

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 104

°F while motors with
class “F” insulation can withstand ambient
temperatures to +140

NOTE: IT IS RECOMMENDED THAT THE CUSTOMER
PROVIDE ADEQUATE FREEZE PROTECTION FOR THE
COILS.
UNITS WITH UL APPROVAL HAVE A MAXIMUM
AMBIENT TEMPERATURE REQUIREMENT OF 104°F.

° F (60°C).

Most control components are mounted inside the
units. Depending on system configuration, these
controls may include damper actuat ors, dir ty filter
switches, averaging temp er ature sensors, low limit
switches, point temperature switches, and inlet guide
vane actuators. Variable frequency drives, starters,
PCMs, control transformers, static pressure
transducers, DC power supplies, customer interface
relays, etc. will be in enclosures mounted on the
inside of the unit.

Small items that cannot be factory-mounted will ship
inside the control enclosures. These controls may
include space temperature sensors, outside air
temperature sensors, and humidity sensors.

All control valves will ship directly to the “ship to
address” from the vendor, unless another address
was given on the order.

All constant volume or variable air volume control
systems are provided with 120 to 24 VAC control
transformers. Unless ordered with a factory­mounted/wired starter or variable frequency drive,
the customer must provide 120 VAC control power,
50/60 hz, typically 3 amps for unit sizes 3 - 50, and 5
amps for unit sizes 66 -100. A dedicated 15 amp
circuit is recommended.

A T-Series Climate Changer unit and/or field-installed
accessories that must be stored for a period of time
prior to being installed MUST be protected from the
elements. The PCM and all other electrical/electronic
components should be stored in conditions of -20 ­120°F and 5 - 95% relative humidity non-condensing.
Electrical components ARE NOT moisture-tolerant

The warranty will not cover damage to the unit or
controls due to negligence during storage. A
controlled indoor environment is recommended for
proper storage. For further storage considerations,
refer to “Storage Considerations” in the next section.

The T-Series Climate Changer is available with a
wide array of factory mounted controls. They include
the Programmable Control Module (PCM), motor
starters, and Variable Frequency Drives (VFD).

Storage Considerations

General

The Trane T-Series Climate Changer air handler is
an outdoor unit and requir es no spec ial prot ecti on for
storage before installation. Keep the equipment in
the original shipping container for protection and
ease of handling. The warranty will not cover

damages to the unit due to negligence during
storage.

For longer periods of storage, allow enough
clearance around the unit to perform periodic
inspection and maintenance of the equipment. In
addition, loosen belt tension on drive belts.

Long Term Storage

Every two weeks, rotate the fan and motor shaft thirty
revolutions by hand. Check for free rotation.

Every six months, check fan shaft bearings and
grease lines. Add grease using a manual grease gun
following the lubrication recommendations in the
Periodic Maintenance section.

Check the motor lubrication; remove and clean
grease plugs and check for the presence of moisture
in the grease. If moisture is present, remove the
motor and send it to an authorized repair shop for
bearing inspection/replacement. If no moisture is

present, refer to the motor manufacturer’s lubrication
recommendation for proper lubrication.

Resolving Shipping Damage

The T-Series Climate Changer ships FOB. If damage
has occurred to the unit sections during shipment,
the following instructions should be completed:

1 Make specific notation describing the damage on

the freight bill.

2 Report all claims of shipping damage to the

delivering carrier immediately.
