instructions.
h. Do not allow the bottles to overflow. (Not more than 80% of liquid charge by volume).
i. Do not exceed the maximum working pressure of the cylinder, even temporarily.
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 must be removed, ensure that they have been
evacuated to an acceptable level to ensure that no flammable refrigerant remains 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.
