CAUTIONS RELATED TO NEW REFRIGERANT Cautions for units utilizing refrigerant R410A Use new refrigerant pipes. Do not use refrigerant other than R410A. In case of using the existing pipes for R22, be careful with If other refrigerant (R22 etc.) is used, chlorine in refrige- the followings.

Check if existing air conditioner can operate.
- Page 7 (2) Cautions for refrigerant piping work New refrigerant R410A is adopted for replacement inverter series. Although the refrigerant piping work for R410A is same as for R22, exclusive tools are necessary so as not to mix with different kind of refrigerant. Furthermore as the working pressure of R410A is 1.6 time higher than that of R22, their sizes of flared sections and flare nuts are different.
