When transferring refrigerants into the cylinders, ensure that only appropriate recovery cylinders are used. Ensure
that the correct number of cylinders is available to hold the entire system load. All bottles to be used are designated
for the recovered refrigerant and are labelled for this refrigerant (i.e. special bottles for refrigerant recovery).
Cylinders must be equipped with a pressure relief valve and 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 must be removed, ensure that they have been evacuated to an acceptable level to
ensure that no flammable refrigerant remains 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.
