RECOVERING
• When removing refrigerant from a system. either for servicing or decommissioning,
it is recommended good practice that all refrigerants are removed safely.
• When transferring refrigerant into cylinders, ensure that only appropriate refrigerant
recovery cylinders are employed. Ensure that the correct number of cylinders for
holding the total system charge is 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-off 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 all appropriate refrigerants including, when applicable, flammable 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 appliance, 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 it 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 flammable 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 all is drained from a system,
it shall be carried out safely.
