refrigerant. The label must be dated and signed.
Ensure that there are labels on the equipment
stating the equipment contains ammable
refrigerant.
16. Recovery
When removing refrigerant from a system,
either for servicing or decommissioning,
it is recommended good practice that all
refrigerants are removed in a safe manner.
When transferring refrigerant into cylinders,
ensure that only appropriate refrigerant
recovery cylinders are employed.
Ensure that the correct number of cylinders
for holding the total system charge is available.
All cylinders to be used are designated for
the recovered refrigerant and labelled for
that refrigerant (i.e. special cylinders for
the recovery of refrigerant). Cylinders shall
be complete with pressure relief valve and
associated shut- o valves in good working
order. Empty recovery cylinders are evacuated
and, if possible, cooled before recovery
occurs.
The recovery equipment shall be in good
working order with a set of instructions
concerning the equipment that is at hand and
shall be suitable for the recovery of ammable
refrigerants. In addition, a set of calibrated
weighing scales shall be available and in good
working order. Hoses shall be complete with
leak- free disconnect couplings and in good
condition. Before using the recovery machine,
check that it is in satisfactory working order,
has been properly maintained and that any
associated electrical components are sealed
to prevent ignition in the event of a refrigerant
release. Consult manufacturer if in doubt.
The recovered refrigerant shall be returned to
the refrigerant supplier in the correct recovery
cylinder, and the relevant Waste Transfer
Note arranged. Do not mix refrigerants in
recovery units and especially not in cylinders.
If compressors or compressor oils are to
be removed, ensure that they have been
evacuated to an acceptable level to make
certain that ammable refrigerant does not
remain within the lubricant. The evacuation
process shall be carried out prior to returning
the compressor to the suppliers. Only electric
heating to the compressor body shall be
employed to accelerate this process. When oil
is drained from a system, it shall be carried out
safely.
Important Note Regarding Fluorinated
Gasses
- Fluorinated greenhouse gases are contained
in rmly sealed equipment. For specic
information on the type, the amount and the
CO
2
equivalent in tonnes of the uorinated
greenhouse gas (on some models), please refer
to the relevant label on the unit itself.
- Installation, service, maintenance and repair of
this unit must be performed only by a certied
technician.
- Unit un- installation and the recycling of, must
be performed by a certied technician.
