Controls - Trane CLCH-IM-16A Installation And Maintenance Manual

Each section of a T-Series Climate Changer is
identified with a multi-character model number and
serial number. The model number precisely identifies
a particular section. Refer to model number and
serial number when ordering parts or requesting
service.
If the unit ships as individual sections or section
subassemblies refer to the nameplate for customer
tagging information and section position to insure
proper placement of the sections during assembly.

Controls

Wiring Sizes and Connections
Entrances are provided for field installation of high
and low voltage wiring through a pipe/nipple
connection in the base of the unit. The low and high
voltage connections are on opposite sides of the unit
on sizes 3 - 50 and on the same side for sizes 66 -
100.
CAUTION
The high and low voltage wire
raceways for the T-series units are
intended for factory wiring ONLY.
Do not use these raceways for
field uses. Failure to follow these
instructions can result in damage
to the unit.
Wiring to the unit must be provided by the installer
and must comply with all national and local electrical
codes. The motor nameplate includes a wiring
diagram. If there are any questions concerning the
wiring of the motor be sure to take the motor
manufacturer's name, model number, and serial
number and contact your local Trane representative
for assistance.

Most control components are mounted inside the
units. Depending on system configuration, these
controls may include damper actuators, dirty filter
switches, averaging temperature 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 factory-
mounted/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.
