•
The recovery procedure is monitored at all times by skilled personnel;
•
The recovery equipment and tanks comply with suitable standards.
•
If possible, pump the cooling system.
•
If it is not possible to obtain a vacuum, make sure that a collector removes the refrigerant from various
parts of the system.
•
Before proceeding with the recovery, check that the tank is located on the scales.
•
Start up the recovery machine and use it following the instructions by the manufacturer.
•
Do not fill the tanks excessively. (Do not exceed 80% of the liquid volume).
•
Do not exceed the tank's maximum operating pressure, not even momentarily.
•
Once the tanks are filled correctly and the process is over, make sure that the tanks and equipment
are immediately removed from the site and that all insulation valves on the equipment are closed.
•
The refrigerant recovered must not be loaded into another cooling system unless it has been cleaned
and checked.

Equipment must be labelled reporting the dismantling and emptying of the refrigerant.
Labels must be dated and signed.
Make sure all the equipment is labelled and reporting the presence of flammable refrigerant.

When removing the refrigerant from the system, please adopt good practices to remove all refrigerants
safely in case of both assistance or decommissioning operations.
When transferring the refrigerant into the tanks, make sure only suitable tanks are used to recover the
refrigerant.
Make sure enough tanks are used.
All the tanks to be used are designated for the recovered refrigerant and are labelled for that specific
refrigerant (e.g. special tanks for refrigerant collection.
Tanks must be equipped with a perfectly-functioning safety valve and relative interception valves.
Empty recovery tanks are evacuated and, if possible, cooled before recovery.
Recovery equipment must be perfectly functioning with the respective instruction booklets at hand and they
must be suitable to recover flammable refrigerants. A series of perfectly-functioning calibrates scales must
also be available.
Flexible tubes must be equipped with leak-proof disconnection fittings in good condition. Before using the
recovery machine, make sure it is in good condition, maintained and that all associated electrical
components are sealed to avoid combustion in case of a refrigerant leak. Please contact the manufacturer
in case of doubt.
The refrigerant recovered must be taken to the supplier in suitable recovery tanks and with the relative
waste transfer note suitably filled in.
Do not mix the refrigerants in the recovery units nor in the tanks.
If it is necessary to remove compressors or compressor oils, make sure they are evacuated to an
acceptable level to make sure no trace is left of the flammable refrigerant inside the lubricant. The
evacuation process must be performed before taking the compressors back to the suppliers.
The electric resistance must be used with the compressor body only to accelerate this process.
Operations to discharge the oil from the system must be performed in full safety.
