3.14 Air extraction (all devices)
3.14.1 Position and function
Air extraction is made through the steam air extractor (D1) on the
sterilisation chamber, the air extractor valve (Y9) and the needle valve
(N1, when necessary).
When the steam in the sterilisation chamber is saturated, the steam air
extractor closes. The air now flows out easily via the needle valve to allow
any residual air pockets to escape.
Position of the needle valve (N1):
The needle valve is opened by

Steam air extractor
If the steam air extractor does not close, then the capsule may
not be properly centred (e.g. due to transport). The capsule can
be realigned in the central position by gently tapping the steam
air extractor (e.g. using a screwdriver).
