associated shut-off valves in good working order. Empty recovery cylinders are
evacuated and, if possible, cooled before recovery begins.
Recovery equipment must be in good working order and accompanied by
instructions regarding the equipment that is within reach and must be adapted to
the recovery of flammable refrigerants. In addition, a set of calibrated scales for
weighing must be available and in good working order. The hoses must be equipped
with leak-proof disconnection sleeves and be in good condition. Before using the
recovery machine, check that it is in good working order and has been properly
maintained and that all associated electrical components are sealed to prevent
ignition in the event of refrigerant release. In case of doubt, consult the
manufacturer.
The recovered refrigerant must be returned to its supplier in the correct recovery
bottle and the corresponding waste transfer note must be established. Do not mix
refrigerants in recovery units and in particular in bottles.
If compressors or compressor oils need to be removed, ensure that they have been
evacuated to an acceptable level to ensure that there is no flammable refrigerant left
in the lubricant. The evacuation process must be completed before returning the
compressor to its supplier. Only an electric heater should be used on the compressor
body to accelerate this process. When oil is extracted from a system, it must be done
safely.
