INDOOR COIL / AIR HANDLER SUBSTITUTIONS
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, CB30M and CB31MV air handlers can be used in place of the
CB26XUH, CBX32M and CBX32MV, respectively.
The expansion device is based on the size of the outdoor unit. The factory installed RFC or TXV on the
C33/CB26UH/CB31MV/CB30M must be replaced to correspond to the outdoor unit. The correct TXV’s are:
3 ton air conditioners 56J19
4−5 ton air conditioners 56J20
Example:
A four−ton air conditioner is being installed. The ARI table shows that CBX32MV−048 is a matching air handler. A
CB31MV−51 with a 56J20 TXV can be used in its place.
