• All personal protective equipment is available and being used

correctly;

• The recovery process is supervised at all times by a competent

person;

• Recovery equipment and cylinders conform to the appropriate

standards.

4. Pump down refrigerant system, if possible.

5. If a vacuum is not possible, make a manifold so that refrigerant can

be removed from various parts of the system.

6. Make sure that cylinder is situated on the scales before recovery

takes place.

7. Start the recovery machine and operate in accordance with

manufacturer’s instructions.

8. Do not overﬁll cylinders. (No more than 80% volume liquid charge).

9. Do not exceed the maximum working pressure of the cylinder, even

temporarily.

10. When the cylinders have been ﬁlled correctly and the process

completed, make sure that the cylinders and the equipment are

removed from site promptly and all isolation valves on the equipment

are closed off.

11. Recovered refrigerant shall not be charged into another refrigeration

system unless it has been cleaned and checked.

Labelling

Equipment shall be labelled stating that it has been de-commissioned

and emptied of refrigerant. The label shall be dated and signed. Ensure

that there are labels on the equipment stating the equipment contains

ﬂammable refrigerant.

Recovery

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.
