• When transferring refrigerant into cylinders, ensure that only
appropriate refrigerant recovery cylinders are used. Ensure that the
correct numbers 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.
• 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 flammable
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 the 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 the cylinders.
• If compressors or compressor oils are to be removed, ensure that
they have been evacuated to an acceptable level to make sure
that flammable 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.
