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.

Competence of service personnel Information of procedures additional to usual information for refrigerating appliance

installation, repair, maintenance and decommission procedures is required when an appliance with FLAMMABLE

REFRIGERANTS is affected. The training of these procedures is carried out by national training organizations or

manufacturers that are accredited to teach the relevant national competency standards that may be set in legislation.

The achieved competence should be documented by a certificate.

5) Label the equipment as indicated below:

Labeling

Equipment shall be labeled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated

and signed. For appliances containing FLAMMABLE REFRIGERANTS, ensure that there are labels on the equipment stating

the equipment contains FLAMMABLE REFRIGERANT.

Decommissioning

If safety is affected when the equipment is taken out of service, the REFRIGERANT CHARGE shall be removed before

decommissioning.

Ensure sufficient ventilation at the equipment location.

Be aware that malfunction of the equipment may be caused by refrigerant loss and a refrigerant leak is possible.

Discharge capacitors in a way that won't cause any spark; using a Supco CapDis tool.

Remove the refrigerant. If recovery is not required by national regulations, drain the refrigerant to the outside. Take care

that the drained refrigerant will not cause any danger. In doubt, one person should guard the outlet. Take special care that

drained refrigerant will not float back into the building.

When FLAMMABLE REFRIGERANTS are used:

A) Evacuate the refrigerant circuit.

B) Purge the refrigerant circuit with oxygen-free nitrogen for 5 min.

C) Evacuate again.

D) Fill with nitrogen up to atmospheric pressure.

E) Put a label on the equipment that the refrigerant is removed.
