CX34 upow coils and all Lennox air handlers (except CB26UH “R”) are
shipped with a factory installed TXV. In most cases, no change out of the valve
is needed.
If a change out is required it will be listed in the “TXV SUBSTITUTIONS” table.
The correct TXV must be ordered and eld installed. C33 coils and all horizontal
and downow coils are shipped without a TXV. The TXV must be ordered and
eld installed.
