Safety precautions
• 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
fl
ammable 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.
