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.
