Introduction

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.

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.

Each unit is provided with a nameplate. This nameplate includes unit model number, serial number and electrical data.

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 assure 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.

Protecting the

Environment

World environmental scientists have concluded, based on the best currently available evidence, that ozone in our upper atmosphere is being reduced due to the release of 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 atmosphere resulting from installation, operation, routine maintenance, or major service 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!
