Proceed as follows to mount the collection tube:
1 Mounting the exhaust air collection tube
￭ Insert the exhaust air collection tube with both support pins into
the collection tube holders on the 892 Professional Rancimat in
such a way that the connector to the exhaust air removal is
located to the rear.
2 Connecting the measuring vessels
￭ Screw the M8/olive tubing adapter into the Out opening of the
measuring vessel cover.
￭ Connect one end of the silicone tubing to the M8/olive tubing
adapter.
￭ Insert the other end of the silicone tubing into the corresponding
opening on the collection tube.
￭ Seal the unused openings on the collection tube with the
enclosed stoppers.
3 Connecting the exhaust air collection tube
￭ Connect a suitable tubing to the connector of the exhaust air col-
lection tube and connect it to an active suction device (e.g. water
jet pump).
3.2.6 Mounting the oil separator
If samples with a high content of highly volatile compounds are used,
there is a risk that the sample is transferred to the measuring vessel in the
vapor phase. This can compromise the conductivity measurement. The
amount of oil contained in the vapor phase can be reduced by means of
the oil separator (6.2753.200). The use of the oil separator is recommen-
ded if the conductivity measurement is compromised by the presence of
the sample in the measuring vessel

NOTE
An additional 8 pieces of silicone tubing (6.1816.010) are required if 8
oil separators are used.
NOTE
The oil separators must be cleaned after each measurement (see Chap-
ter 4.3.5, page 38).
