ARI RATINGS − INDOOR COIL / AIR HANDLER SUBSTITUTION
Substituting Coils in the ARI Tables
Most R−22 and R−410A indoor coils and air handlers are
the same except for the factory installed expansion
device. C33 coils can be used in place of the CX34 coils,
CB26UH−R, CB27UH, and CB30M air handlers can be
used in place of the CBX26UH, CBX27UH, and CBX32M,
respectively.

The expansion device is based on the size of the outdoor
unit. The factory installed RFC or TXV on the
C33/CB26UH−R/CB27UH/CB30M must be replaced to
correspond to the outdoor unit. The correct TXV's are:
1.5−3 ton air conditioners
3.5 ton air conditioners
4−5 ton air conditioners
Example:
A four−ton air conditioner is being installed. The ARI table
shows that CBX32M−048 is a matching air handler. A
CB30M−51 with a 91M02 TXV can be used in its place.
