Before attempting the procedure ensure that:

–

Mechanical handling equipment is available, if required, for handling refrigerant

cylinders;

–

All personal protective equipment is available and being used correctly;

–

The recovery process is always supervised by a competent person;

–

Recovery equipment and cylinders conform to the appropriate standards.

Pump down refrigerant system, if possible.

If a vacuum is not possible, make a manifold so that refrigerant can be removed from

various parts of the system.

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

Start the recovery machine and operate in accordance with manufacturer's instructions.

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

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 site promptly and all isolation valves

on the equipment are closed off.

k) Recovered refrigerant shall not be charged into another refrigeration system unless it has

been cleaned and checked.

15. 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.

16. 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.

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

flammable refrigerants.
