5. Connect the feed tube (8) to the Ultrasonic nozzle (connector (b)) while in­
tegrating the damper into the tube. (See below)
6. Connect the spray gas (compressed air or nitrogen), as provided by the in­
stallation of the B­290, to the nozzle (connector (a)). The spray gas will
serve as cooling gas for the nozzle.

5 Damper
The damper is integrated into the feeding tube. To install it proceed as follows:
1. Select the suitable type of tube for the feed solution.
2. Prepare a piece of tube of the adequate length for the connection between
the feed solution vessel on the product feed table and the corresponding
connector (2) of the ultrasonic nozzle.
3. Cut of a short piece of the prepared tube (3).
4. Connect the y­piece (4) to the longer part of the feed tube (1) and the
shorter part (3), as described above.
5. Slide the damper (5) on the free connector of the Y­piece (4).
6. Insert the free end of the feed tube into the feed solution vessel. Make
sure in dips into the solution.
NOTE
The damper can also be used to remove a slight blockage in the nozzle by sim­
ply squeezing it. This will generate a short overpressure impulse that ­ in some
cases ­ is sufficient to remove the blockage.
