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 il is in satisfactory working
order, has been properly maintained and that any associated electrical components are sealed to prevent igni-
tion 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.
lf 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 healing to the compressor
body shall be employed to accelerate this process. When oil is drained from a system, il shall be carried out
safely.
