Note
Instead of the measuring vessel 6.1428.100 made from polycarbonate,
the optionally available measuring vessel 6.1428.020 made from clear
glass can be used. In contrast to the polycarbonate vessel, the measur-
ing vessel 6.1428.020 can also be cleaned with acetone.
3.2.5 Mounting the exhaust collection tube (optional accessories)
The optionally available exhaust collection tube 6.2757.000 can be moun-
ted on the 743 Rancimat for targeted removal of the exhaust air. In addi-
tion to the exhaust collection tube, 8 silicone tubings 6.1816.010
(220 mm) also have to be ordered.
Proceed as follows to mount the collection tube:
1 Mount the exhaust collection tube
￭ Insert the exhaust collection tube with both nozzles into the col-
lection tube holders (3-1) on the Rancimat in such a way that the
connection to the exhaust air removal is located to the rear.
2 Connect the measuring vessels
￭ Screw the tubing adapter M8 / olive (5-11) into the opening Out
(5-12) of the measuring vessel cover.
￭ Connect the one end of the silicone tubing (5-2) to the tubing
adapter M8 / olive.
￭ 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 plugs E.400.0010.
3 Connect the exhaust collection tube
￭ Connect a suitable tubing to the connection of the exhaust collec-
tion tube and connect this to an active suction device (e.g. water
jet pump).
