12.1 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 it has to be subjected to the
mentioned norms. A particular care is recommended during service operations in order to reduce as much as possible any
refrigerant loss.
This equipment contains R134a refrigerant in the amount as stated in the specification. Do not vent R134a into
the atmosphere: R134a, is a fluorinated greenhouse gas with a Global Warming Potential (GWP) = 1300.
It should only be serviced or dismantled by professional trained personnel.
13 TROUBLESHOOTING
This section provides useful information for diagnosing and correcting certain troubles which may occur. Before starting the
troubleshooting procedure, carry out a thorough visual inspection of the unit and look for obvious defects such as loose
