5.1.1 Environmental protection
According to the norms dealing with the use of depleting stratospheric ozone substances, it is forbidden to release
refrigerants fluids in the atmosphere. They have to be collected and delivered to the seller or to proper gathering points
at the end of their operating life. Refrigerant R134A is mentioned among controlled substances and for this reason
