General Information

Use this manual to install, startup, operate, and maintain the Custom Climate Changer™ air

handler. Carefully review the procedures discussed in this manual to minimize installation and

startup difficulties.

Each Trane air handler section is provided with a nameplate which identifies the type of section,

customer tagging information, the section serial number, the section position, the service model

number, and electrical data.

Note: This information is required when ordering parts or requesting service for a Trane air

handler.

Operating Environment

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).

For the units furnished with gas furnaces, the heating demands require a special motor to

withstand the higher temperatures. These motors are furnished with Class “H” insulation to

withstand this rigorous duty.

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 93 for more information.

Unit Description

Custom Climate Changer™ air handlers are designed for a variety of controlled-air applications.

The basic unit consists of a fan, heating and/or cooling coils, filters, and dampers. See the unit

submittal drawings for detailed descriptions.

The fans are internally isolated. To insure fan stability, the unit ships with a minimum of four lock-

down devices that prevent the fan from shifting during shipment and installation. These spacers

must be removed prior to fan operation to ensure proper vibration isolation. Retain these spacers

for use in adjusting fan isolators if required.

The units are available with factory mounted controls for climate and humidity control. These can

be use as stand-alone devices or operate with a complete controls system. End devices include

factory-mounted starters and variable speed drives.

Custom Climate Changer™ air handlers ship as complete assemblies or in sections. Some jobsite

assembly is required when the units ship in sections.
