Environmental Concerns!

Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment.Trane advocates the responsible handling of all refrigerants-including industry replacements for CFCs such as HCFCs and HFCs.

Responsible Refrigerant Practices!

Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified.The Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that

WARNING

Hazardous Voltage w/Capacitors!

Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/ tagout procedures to ensure the power cannot be inadvertently energized. For variable frequency drives or other energy storing components provided by Trane or others, refer to the appropriate manufacturer’s literature for allowable waiting periods for discharge of capacitors. Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.

For additional information regarding the safe discharge of capacitors, see PROD-SVB06A-EN

General Data

Unit Description

Model CCRC/CIRC units function as the outdoor condenser unit for appropriately sized split refrigeration systems. These units operate in conjunction with a matched indoor compressor/evaporator configuration (Trane models SCRF, SIRF, SCRG, or SIRG) and provide refrigerant condensing for these systems down to a normal ambient temperature of 45°F. Operation to 0°F ambient is possible with the addition of the optional external mount low ambient dampers. Refer to the “Low Ambient Damper” section in this manual.

Model CCRC/CIRC remote air cooled condensers are dehydrated, leak tested, and charged with a holding charge of dry nitrogen. Units are tested for proper control operation before shipment.

The factory provided unit-mounted control panel contains all required fan cycling controls, compressor interlocks

and 115 V control power transformer. Each unit features two independent refrigerant circuits with an integral subcooling loop.The slab condenser coils are aluminum fins bonded to copper tubing. Louvered condenser grills are for coil protection and are an orderable option. Direct drive, vertical discharge fans are provided with built-in current and overload protection. Head pressure control dampers are available if low ambient operation is required.

A bag containing the installation/ operation/maintenance manual, schematics, and other pertaining literature is provided and located in the control panel. Read all literature pertaining to unit before installation and operation. Figure 1 illustrates CCRC/CIRC exterior component locations
