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.
l
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.
l
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.
l
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.
