Disposal and recycle
Label：
The unit shall be labeled with data and note after scrapping and discharging
refrigerant. Make sure the label on the unit can reflect the R32 refrigerant which it
has been filled.
Recycle：
It's recommended to remove the refrigerant in the system before maintenance and
disposal.
Put the refrigerant into the specialized refrigerant tank with refrigerant label. The
refrigerant tank shall be equipped with pressure-relief valve and cut-off valve, which
are in good condition. If possible, the empty tank should be dealt with vacuum
pumping before using and keep it in normal temperature.
Recycling device shall be kept in good working status and equipped with operation
instructions for reference. The device shall be applicable for the recycle of R32
refrigerant. In addition, qualified weighing apparatus which can be used normally
shall be prepared. The hose shall adopt removable connector without leakage for
connection and keep it in good status. Check if the recycling device is in normal
status before using it and if it is properly stored with all electrical components sealed
to prevent fire hazard caused by refrigerant leakage. If you have any question,
please consult with the manufacturer.
The recycled refrigerant shall be put in proper container attached with transportation
instruction and send it back to the refrigerant manufacturer. Do not mix different
refrigerants in the refrigerant recycle device, especially the refrigerant tank.
When disassembling the compressor or clearing the compressor oil, make sure the
compressor has been dealt with vacuum pumping to suitable level, so that there is
no R32 refrigerant remained in the lubricant. Vacuum pumping shall be done
before the compressor is sent back to the supplier. Only electric heating can be
adopted for heating the shell of compressor in order to speed up the course. When
oil is drained from the system, please ensure the safety.
