10 Final Check
3.7 Checking aspiration function
Necessary with the Suction MODULE and the Combi MODULE
1. Open the valve of the oxygen bottle slowly.
2. Switch on aspiration.
3. Suction MODULE:
Turn the regulator knob 9 as far right as it will
go. Remove the vacuum tube and hold vacu-
um connection 10 closed.
Combi MODULE:
The vacuum is locked at ≥ – 0.5 bar (at
4.5 bar O
2
input pressure) and cannot be read
off the manometer 6 directly. In this case it is nec-
essary to connect the Weinmann test manometer
WM 15294 to vacuum connection 10.
4. When the manometer 6 on the Suction
MODULE or the test manometer connected to
the Combi MODULE are showing a constant
reading, this should be not less than – 0.5 bar
at an O
2
input pressure of 4.5 bar.
5. To check the OMNIVAC aspirate collection
set for leaks, replace the vacuum tube and
hold the opening of the end piece closed.
6. A reading of at least – 0.5 bar must be ob-
tained within 30 seconds.
If this level is not reached, the connections must
be checked for leaks.
