10. Decommissioning

• Before carrying out this procedure, it is 

essential that the technician is completely 

familiar with the equipment and all its details.

• 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 over fi ll 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 fi 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.

k)  Recovered refrigerant shall not be 

charged into another refrigeration system 

unless it has been cleaned and checked.

• Electrostatic charge may accumulate and 

create a hazardous condition when charging 

or discharging the refrigerant.

To avoid fi re or explosion, dissipate static 

electricity during transfer by grounding and 

bonding containers and equipment before 

charging/discharging.

11. 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 

fl ammable refrigerant.

12. 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.

• 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 

fl 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 fl 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.
