NOTE See the outdoor unit installation instructions and
the Lennox Engineering Handbook for approved fixed
orifice match−ups and application information.
CB26UH−R units are equipped with a factory−installed
refrigerant flow control (RFC) device (see table 1 on
Page 3).
IMPORTANT
If a unit equipped with an RFC device is used in an ap-
plication which requires conversion to an expansion
valve, the fixed orifice must be removed before the ex-
pansion valve is installed.
