Vacuson 40/60

7.1 Bacterial Filter

As one-way element, the Bacterial Filter must be periodically changed, and
immediately when foam or infectious material is sucked in.
(Art. Nr. see 9. Replacement parts and numbers)

7.2 Secretion Jar

Because the inflow of secretion material mixed with air produces a build-up of foam in the Secretion
Jar, an anti-foaming agent is required. Before operation, put anti-foaming agent in clean and dry
Secretion Jar. Do not add disinfecting agents, as they increase the build-up of foam.
Check carefully that the Secretion Jar is in good condition. Make sure that there are no cracks or chips
and that the rim is unmarked. This is important to insure a properly sealed system, and enables the
Suction Pump to function correctly.

7.3 Inspection of Overflow Protection Elements

To insure proper function, the Overflow Protection must be checked out from time to time:
1) Connect Secretion Lid, without Jar, to the Bacteria Filter tube.
2) Turn regulator „VACUUM" on Control Unit clockwise to open.
3) Turn Vacuum Suction Pump on.
4) Press Overflow Protection float on Secretion Lid.
5) Vacuum Meter should indicate increasing value, to a maximum of > -0.8bar.
If the maximum vacuum is not indicated, the Overflow Protection must be
disassembled, cleaned, and seals replaced

7.4 Disassembly of the Overflow Protection System

1) Unscrew threaded Overflow Protection connector (1)
from Secretion Jar connector.
2) Remove connector seal (2).
3) Install new seal.
4) Clean Overflow Protection with float.
5) Screw threaded Overflow Protection connector (3)
back on.
Float Check following disassembly:
1) Hold lid vertical.
2) Press float repeatedly against lid.
3) Check that float falls back independently to normal position.
If float does not fall back, cleaning must be repeated.
