Labelling
• The parts shall be labelled to ensure that they have
been decommissioned and emptied of refrigerant.
• The labels shall be dated.
• Make sure that the labels are affixed on the system to
notify it contains flammable refrigerant.
Recovery
• When removing refrigerant from the system for
servicing or decommissioning, it is recommended to
remove the entire refrigerant.
• When transferring refrigerant into cylinders, make
sure that only the refrigerant recovery cylinders are
used.
• All cylinders used for the recovered refrigerant shall
be labelled.
• Cylinders shall be equipped with pressure relief valves
and shut-off valves in a proper order.
• The recovery system shall operate normally according
to the specified instructions and shall be suitable for
refrigerant recovery.
• In addition, the calibration scales shall operate
normally.
• Hoses shall be equipped with leak-free disconnect
couplings.
• Before starting the recovery, check for the status of
the recovery system and sealing state. Consult with
the manufacturer if suspected.
• The recovered refrigerant shall be returned to the
supplier in the correct recovery cylinders with the
Waste Transfer Note attached.
• Do not mix refrigerants in the recovery units or
cylinders.
• If compressors or compressor oils are to be removed,
make sure that they have been evacuated to the
acceptable level to ensure that flammable refrigerant
does not remain in the lubricant.
• The evacuation process shall be performed before
sending the compressor to the suppliers.
• Only the electrical heating to the compressor body is
allowed to accelerate the process.
• Oil shall be drained safely from the system.
• Never install a motor-driven equipment to prevent
ignition.
• Empty recovery cylinders shall be evacuated and
cooled before recovery.
