j. When the cylinders have been properly filled and the process is complete, ensure that the cylinders and equipment are
removed from the site quickly and that all equipment isolation valves are closed.
k. The recovered refrigerant must not be loaded into another refrigeration system unless it has been cleaned and checked.
- Labelling
A label must be affixed to the equipment indicating that it has been taken out of service and drained of its refrigerant. This
label must be dated and signed. Ensure that there are labels on equipment indicating that it contains flammable
refrigerants.
Recuperation
-
When draining a system of its refrigerant for service or shutdown operations, it is recommended good practice to safely
remove all refrigerants.
When transferring refrigerants into the cylinders, ensure that only appropriate recovery cylinders are used. Ensure that the
correct number of cylinders is available to hold the entire system load. All bottles to be used are designated for the
recovered refrigerant and are labelled for this refrigerant (i.e. special bottles for refrigerant recovery). Cylinders must be
equipped with a pressure relief valve and associated shut-off valves in good working order. Empty recovery cylinders are
evacuated and, if possible, cooled before recovery begins.
Recovery equipment must be in good working order and accompanied by instructions regarding the equipment that is
within reach and must be adapted to the recovery of flammable refrigerants. In addition, a set of calibrated scales for
weighing must be available and in good working order. The hoses must be equipped with leak-proof disconnection sleeves
and be in good condition. Before using the recovery machine, check that it is in good working order and has been properly
maintained and that all associated electrical components are sealed to prevent ignition in the event of refrigerant release.
In case of doubt, consult the manufacturer.
The recovered refrigerant must be returned to its supplier in the correct recovery bottle and the corresponding waste
transfer note must be established. Do not mix refrigerants in recovery units and in particular in bottles.
If compressors or compressor oils need to be removed, ensure that they have been evacuated to an acceptable level to
ensure that there is no flammable refrigerant left in the lubricant. The evacuation process must be completed before
returning the compressor to its supplier. Only an electric heater should be used on the compressor body to accelerate this
process. When oil is extracted from a system, it must be done safely.
