Important Information
This document provides installation instructions for Trane replacement coils. It is intended for use by qualified personnel only. Improper installation, adjustment, or alteration can result in death, serious injury, or property damage.
Safety Precautions
- Qualified Personnel Only: Installation and servicing must be performed by trained professionals.
- Hazardous Voltage: Disconnect all electric power, including remote disconnects, before servicing. Follow proper lock out/tag out procedures.
- Refrigerant Handling: The system contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure before opening the system.
- Brazing: If using existing refrigerant lines, ensure all joints are brazed, not soldered. Perform a leak test after mechanical connections.
- Chemical Warning: This product may expose you to chemicals, including lead, known to the State of California to cause cancer and birth defects.
Inspection
Upon receiving the kit, perform the following steps:
- Unpack all components of the kit.
- Check carefully for any shipping damage. Report any damage immediately to the transportation company.
- Verify that all components are present. Report missing components to your supplier at once for replacement with authorized parts.
General Information
Replacement coils are identical to the production coil for all heat pumps, RunTru cooling, and Ameristar cooling units. For Trane and American Standard cooling units, the replacement coil may differ in height but has been verified to perform the same or better than the production coil. It is recommended to change the filter drier when replacing the coil.
Installation and Modifications
One or more of the following modifications may be required to install the replacement coils:

- Gas Manifold: If the gas manifold extends too far below the discharge connection, remove an appropriate amount of tubing from the gas manifold on the replacement coil.
- Filter Drier: If the original unit contains an internal filter drier, it is recommended to convert to a filter drier external to the cabinet.
- Liquid Valve: If the liquid valve connection tube on the replacement coil does not reach the liquid service valve, brazing an extension is required.
