the correct number of cylinders for holding the total system charge are available. All cylinders to be used are designated for the
recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be
complete with pressure relief valve and associated shut-o valves in good working order. Empty recovery cylinders are evacuated
and, if possible, cooled before recovery occurs.
The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at hand and
shall be suitable for the recovery of ammable refrigerants. In addition, a set of calibrated weighing scales shall be available and in
good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition. Before using the recovery
machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components
are sealed to prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt.
The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste
Transfer Note arranged. Do not mix refrigerants in recovery units and especially not in cylinders.
If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain
that ammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out prior to returning the
compressor to the suppliers. Only electric heating to the compressor body shall be employed to accelerate this process. When oil is
drained from a system, it shall be carried out safely.
