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. 
a. Become familiar with the equipment and its operation. 
b. Isolate system electrically. 
c. 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. 
d. Pump down refrigerant system, if possible. 
e. If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the 
system. 
f. Make sure that cylinder is situated on the scales before recovery takes place. 
g. Start the recovery machine and operate in accordance with manufacturer’s instructions. 
h. 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 onthe equipment are closed off. 
k. Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and 
checked.

24. 

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 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 all appropriate refrigerants including, when applicable, 
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 recover 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.
