Liquid refrigerant should be recharged with the cylinder standing on end as shown.

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.
R410A
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.
