Insulated line sets are available for all Friedrich split systems in 15 ft. and 35 ft. lengths. Each line set is equipped with flare nuts on both ends. Both liquid and
suction lines are insulated. Line sets can be joined together with field supplied double female connectors. Each system requires one line set for each indoor
unit installed. On multi-zone systems, line sets should be ordered based on individual indoor unit capacities not total system capacity. For example, a M18DYF
uses 2 line sets for 9,000 btu units, not 1 for the 18,000 btu product.

NOTE: All R410A models have 1/2˝ UNF 20 thread per inch charging and vacuuming ports. An adapter must be used
for 1/4˝ gauges. Adapter part number 67270018 is available through Friedrich parts distributors.
