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-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
manufacturer if in doubt. The recovered refrigerant shall be
returned to the refrigerant supplier in the correct recovery cylinder,
and the relevant Waste trransfer 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 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.
