HS40 condensing units use R407C which is an ozone
friendly HFC refrigerant. This unit must be installed with a
matching indoor coil and line set as outlined in the Lennox
Engineering Handbook. HS40 condensing units are de-
signed for use in expansion valve systems only. They are
not designed to be used in RFC systems. An expansion
valve and filter drier approved for use with R407C have
been shipped with the unit. These components must be
installed prior to unit operation.
