Trane’s Charge Assist™ is an automatic, self-charging technology that takes the guesswork out of system installation and maintenance. It enables technicians to push a button and ensure proper refrigerant charge. A standard feature on Trane’s ComfortLink™ II high efficiency systems, this tool ensures that the most efficient residential systems deliver the performance levels specified. To use, installers or technicians connect the refrigerant container to the outdoor unit, pushe one button on the Charge Assist board, and the system begins to charge. A light inside the unit indicates when the charge is complete. Even if the installer or technician is not on hand, when the charge is complete the charging process shuts down automatically.
During maintenance, it will indicate if a unit is under or over charged with refrigerant, enabling the technician to add or recover refrigerant and put the system back in balance.
