11. Recovery
- When refrigerant is removed from a system, either for service or decommissioning, it is
recommended good practice that all refrigerants are removed safely.
- When transferring refrigerant to cylinders, ensure that only suitable refrigerant-recovery
cylinders are used. Ensure that the correct number of cylinders is available to support
the total load of the system. All cylinders to be used are designated for the refrigerant

addition, a set of calibrated weighing scales must be available and in good working order.
Hoses must be complete with disconnect couplings free of leakage and in good running
order. Before using the recovery machine, check that it is in good running order, properly
maintained, and that all associated electrical components are sealed to prevent ignition in
the event of refrigerant release. Consult the manufacturer in case of doubt.

is no refrigerant left in the system. When using the oxygen-free nitrogen end-charge,
the system must be vented to atmospheric pressure to allow for work. This operation is
absolutely vital if brazing operations are to take place on pipes.
- Ensure that the vacuum pump outlet is not near any source of ignition and that ventilation
is available.
