• DD.12 Decommissioning:

Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and

all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried

out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. It

is essential that electrical power is available before the task is commenced.

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 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.

• 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.

• 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 are 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. 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 flammable 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.

• Warning: disconnect the appliance from its power source during service and when replacing parts.

• These units are partial unit air conditioners, complying with partial unit requirements of this International Standard,

and must only be connected to other units that have been confirmed as complying to corresponding partial unit

requirements of this International Standard.
