2.- INSTALLATION
Legislation does not allow refrigerant gas emissions to the atmosphere, so the refrigerants have to be
recycled to avoid being released to the atmosphere. Those recycled refrigerants shall be processed afte-
rwards by an authorized waste manager.
Those components derived from the recycling of the unit have to be managed by authorized waste manager
or be left in local waste facilities according the local normative in each country.
