• Recovery equipment and cylinders conform to the appropriate standards.
d) Pump down refrigerant system, if possible.
e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
f) Make sure that the cylinder is placed on the scales before recovery takes place.
g) Start the recovery machine and operate in accordance with manufacturer's instructions.
h) Do not overfill cylinders. (No more than 80 % liquid charge by volume).
i) Do not exceed the maximum working pressure of the cylinder, even temporarily.
j) When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the
equipment are removed from the site promptly and that all isolation valves on the equipment are closed off.
k) Recovered refrigerant must not be charged into another refrigeration system unless it has been cleaned and checked.
15. Labelling
Equipment must be labelled stating that it has been decommissioned and emptied of refrigerant. The label must be
dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.
16. Recovery
When removing refrigerant from a system, either for servicing or decommissioning, ensuring that all refrigerants are
removed safely is recommended good practice.
When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are used.
Ensure that the correct number of cylinders for holding the total system charge are available. All cylinders to be used
must be designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery
of refrigerant). Cylinders must be complete with pressure relief valves and associated shut-off valves in good working
order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.
The recovery equipment must be in good working order with instructions concerning the equipment being used and
must be suitable for the recovery of flammable refrigerants. A set of calibrated weighing scales must also be available
and in good working order. Hoses must 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. If in doubt consult
the manufacturer.
The recovered refrigerant must 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
ensure that flammable refrigerant does not remain within the lubricant. The evacuation process must be carried out
prior to returning the compressor to the supplier. Only electric heating to the compressor body shall be used to
accelerate this process. Oil must be drained from systems safely.
Fluorinated gases
• Fluorinated gases are contained in hermetically sealed equipment. For information on the type, quantity and CO2
equivalent in tonnes of fluorinated greenhouse gas, please see the label.
• Installation, servicing, maintenance and repair of this unit must be performed by a certified technician.
• The product must be removed and recycled by a certified technician.
