5. The oxygen must be felt to come out at the

12.5 Checking aspiration
Required for Suction
MODULE and Combi
MODULE
1. Open the oxygen supply valve
slowly
.
2. Switch on aspiration.
3.
Suction MODULE:
turn the dial to the right-hand
stop. Take off the vacuum tube and hold
vacuum connection
closed.
Combi MODULE:
the vacuum is permanently set to
≥
– 0.5 bar (at 4.5 bar O
2
inlet pressure) and can-
not be read off directly on the pressure gauge. You
should therefore plug WEINMANN Emergency test
pressure gauge WM 15294 onto connection for
the vacuum
.
4. Read off the value which becomes constant on
the pressure gauge (Suction MODULE) or on the
test pressure gauge (Combi MODULE). This value
must be at least – 0.5 bar at a feed pressure of
4.5 bar.
5.
Suction MODULE:
to check that the OMNIVAC
secretion aspiration system is leaktight, connect
the vacuum tube again and hold the aspiration
opening of the end-piece closed instead.
Combi MODULE:
to check that the OMNIVAC
secretion aspiration system is leaktight, connect
WEINMANN Emergency test pressure gauge
WM 15294 to the end-piece of the fingertip
regulator. Hold the fingertip regulator closed as
you do so.
6. After no more than 30 seconds, at least –
0.5 bar must be displayed.
