2 Warnings (for using R290 refrigerant only)
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 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.
