Safety Information (continued)
1. Become familiar with the equipment and its operation.
2. Isolate system electrically.
3. 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 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 over ll 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 lled 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.
LABELING
Equipment shall be labeled stating that it has been decommissioned and emptied of refrigerant. The label shall be dated and signed. Ensure
that there are labels on the equipment stating the equipment contains ammable 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 labeled 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 ammable 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 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. Consult manufacturer if 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 ammable 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 oil is drained from a system, it shall be carried out safely.
