Unbelievably Fujitsu mentions that R410a is an ecological gas because it does not deplete the ozone layer! Only R12 and R22 deplete the ozone layer, but R12 was banned worldwide in 1994 and R22 is already being phased out in the EU and USA. So I am sorry to inform you that your AC units are not eco-friendly at all.
Really, the installation manual in Portuguese says that the air conditioning unit uses a new HFC refrigerant (R410A).
