New refrigerant R410A cannot be used
for earlier models
1. Compressor specifications are different.
If recharging a R22 or R407C compressor with R410A,
durability will significantly decrease since some of the materials
used for compressor parts are different.
2. Existing tubing cannot be used (especially R22).
Completely cleaning out residual refrigerating machine oil is
impossible, even by flushing.
3. Refrigerating machine oil differs (R22).
Since R22 refrigerating machine oil is mineral oil, it does
not dissolve in R410A. Therefore, refrigerating machine oil
discharged from the compressor can cause compressor
damage.
