including, when applicable, 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.
