Safety precautions
i) Do not exceed the maximum
working pressure of the cylinder,
even temporarily.
j) When the cylinders have been
fi lled correctly and the process
completed, make sure that the
cylinders and the equipment are
removed from site promptly and all
isolation valves on the equipment
are closed off.
k) Recovered refrigerant shall not be
charged into another refrigerating
system unless it has been cleaned
and checked.
• Electrostatic charge may accumulate
and create a hazardous condition
when charging or discharging the
refrigerant.To avoid fi re or explosion,
dissipate static electricity during
transfer by grounding and bonding
containers and equipment before
charging/discharging.
11. Labelling
• Equipment shall be labelled stating
that it has been de-commissioned
and emptied of refrigerant.
• The label shall be dated and signed.
• Ensure that there are labels on the
equipment stating the equipment
contains fl ammable refrigerant.
12. Recovery
• When removing refrigerant from
a system, either for servicing or
decommissioning, it is recommended
good practice that all refrigerants are
removed safely.
• 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 are 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-off valves in good working order.
• 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 fl 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 fl 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.
