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 Transfer Notice 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.
