• 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.
Contact the manufacturer if you are unsure.
• 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
electrical heating of the compressor body shall be employed
to accelerate this process. When oil is drained from a system,
it shall be carried out safely.
