11.18 Labelling
The appliance must be labelled to indicate that it has been decommissioned and emptied of refrigerant. The
label must be dated and signed. Make sure that labels indicating flammable refrigerant content are axed
to the appliance.
11.19 Recovery
• When discharging refrigerant from a system for maintenance or decommissioning reasons, it is recom-
mended to extract the refrigerant safely.
• If the refrigerant is decanted into cylinders, use only cylinders suitable for refrigerant recovery. Verify that
the number of cylinders required to hold the entire system charge is available. All cylinders to be used
shall be designated for the refrigerant recovered and labelled for that refrigerant (special refrigerant re-
covery cylinders). Cylinders shall be equipped with a pressure relief valve and well-functioning shut-o
valves.
• Empty recovery cylinders must be evacuated and, if possible, cooled before recovery.
• The recovery equipment must be in good working order, accompanied by a set of instructions at hand,
and must be suitable for flammable refrigerant recovery. In addition, you will need to prepare a set of
well-functioning calibrated scales.
• The pipes shall be complete with decoupling fittings that are leak-free and in good condition. Before us-
ing the recovery equipment, check that it is in good working order, that it has been properly maintained
and that the associated electrical components are sealed to prevent a risk of ignition in the event of re-
frigerant leakage. If in doubt, consult the manufacturer.
• The recovered refrigerant must be returned to the supplier in the correct recovery cylinders, accompa-
nied by the relevant waste identification form. Do not mix dierent types of refrigerant in recovery units,
especially in cylinders.
• If compressors or compressor oils need to be decommissioned, evacuate them to an acceptable level
to prevent flammable refrigerant from remaining inside the lubricant. The evacuation procedure must be
carried out before returning the compressor to the suppliers. To accelerate this process, only use electric
heating on the compressor body. When extracting oil from the system, drain it using a safe procedure.
11.20 Transport, marking and storage of units
Transport of equipment containing flammable refrigerants
Follow applicable regulations related to transporting these materials.
Markings and signage on equipment
Comply with current regulations.
Disposing of equipment containing flammable refrigerants
Comply with current national regulations.
Equipment storage
The equipment must be stored in accordance with the manufacturer's instructions.
Storage of packaged equipment (not sold)
The packaging material to be stored must be protected so that any mechani-
cal damage to the equipment contained in it cannot cause refrigerant leakage.
The maximum number of appliances that can be stored in the same location is determined by local regula-
tions.
Construction and specifications are subject to product improvement changes without notice. Please contact
the sales agency or manufacturer for further details.
