RECOVERY
•
When draining the refrigerant for maintenance or decommissioning, best practices
should be followed in order to safely drain all of the refrigerant.
•
When transferring refrigerant to a cylinder, make sure that you use a recovery
cylinder that is compatible with the refrigerant. Make sure that the correct number
of cylinders are provided for recovering all of the refrigerant. All cylinders used must
be intended for the recovery of refrigerant and must be labelled for this specific
refrigerant. The cylinders must be equipped with a vacuum valve and a stop gate
in good working order. Empty collection cylinders are drained and, where possible,
cooled before recovery.
•
The recovery equipment must be in good working order, the instructions for using
the equipment must be within reach and the equipment must be compatible for
use with the refrigerant concerned, including, where appropriate, a flammable
refrigerant. Moreover, a set of calibrated scales must be available and in good
working order. The pipework must be complete, have no leaks or disconnected
connectors, and must be in good condition. Before using the recovery unit, check
that it is in good working order, that it has been well maintained and that the
associated electric components are sealed so as to prevent any risk of fire in the event
of refrigerant being released. If you have any doubts, contact the manufacturer.
•
The recovered refrigerant must be sent to the refrigerant supplier in its recovery
cylinder with a waste transfer note. Do not mix different refrigerants in the recovery
units, and in particular in the cylinders.
•
If the compressor has been removed or if oil from the compressor has been drained,
check that the refrigerant has been completely removed to prevent it from mixing
with the lubricant. The draining process must be carried out before returning the
compressor to the supplier. Only the electric heater of the compressor body can
be used to accelerate this process. This operation can be carried out safely once all
liquids within the system have been drained.
