6.2 Refrigerant Identifier
(optional, standard on RI variants)
If the internal or external refrigerant identifier,
connected to the station through the USB cable, is
installed, before performing a recovery operation,
an internal tank filling or the automatic function, the
refrigerant identifier checks the purity of the refrigerant
in the vehicle on which to carry out the operation
(during a recovery or automatic function) or in the
cylinder (when filling the internal tank).
i This procedure was written using screens related
to the recovery or automatic functions. The screens
displayed when filling the internal tank are slightly
different, although the procedure is the same.
