Refrigerant lines must be flushed by a licensed, EPA certified refrigerant technician in accordance with established procedures. Flushing Connections NOTES: s R-410A outdoor systems are not recommended for use with indoor systems that have used R-22 as the refrigerant. However, if this unit is being matched with an approved line set or indoor coil which was previously charged with R-22 refrigerant, or if it is being matched with a coil which was manufactured before January of 1999, the R-22 coil and line set must be flushed prior to installation. s Check the refrigerant lines for size and length.
