3-2. Use R410A exclusive cylinder only.
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.
