7.0 DISPOSAL AND GAS RECOVERY
7.1 DISPOSAL OF THE EQUIPEMENT AND PARTS :
Disposal of the equipment and parts of it must be done in compliance with the laws in force for the
differentiated disposal of waste and / or recycling.
7.2 REFRIGERANT FLUORINATED GAS RECOVERY :
THIS OPERATION MUST BE PERFORMED BY QUALIFIED PERSONNEL
During the maintenance or disposal interventions it is necessary to empty the refrigeration
system from the refrigerant. The emptying operation requires precision. The refrigerant must be
loaded in a special tank (cylinder), with a capacity suitable to contain all the refrigerant present in
the refrigeration system. The cylinders must be specially labeled so that specify clearly that they are
destined to contain recovery refrigerant; they must be used for one type of refrigerant (dedicated
tank for recovery refrigerant). The cylinders must be equipped with working pressure and shut-off
valves. If possible, the empty cylinder must be placed under vacuum and kept at normal
temperature before use. The devices used for the recovery must be in good condition and
equipped with instructions for use; they must be suitable for the recovery of flammable refrigerants.
Weighing instruments must also be supplied with a specific calibration certificate. Removable
components such as the flexible pipe used for inlet and extraction of the refrigerant must be leak
free and always in good condition. Before use, always check that the recovery devices are in good
condition and in good maintenance conditions. Contact the manufacturer if you have any
questions. The recovered refrigerant must be sent to the appropriate recovery centers in appropriate
cylinders with instructions for transport. Do not mix different refrigerants in recovery devices,
especially in cylinders. During transport, the space in which the air conditioners are charged must not
be sealed. When loading and unloading the air conditioners, provide for the correct protection
measures to prevent the units from being damaged. When dismantling the compressor or removing
the compressor oil, make sure that the compressor is adequately depressurized to prevent the
presence of residual amounts of refrigerant in the lubricating oil. Complete emptying before
returning the compressor to the manufacturer. Pay attention to safety when draining the oil from the
system.
