1. In all lavatories: In the vacuum toilet system:
- push each flush switch 51MG - the vacuum generator 37MG starts to
with a time delay of 15 +3 -3 operate each time when the flush
s. switch is pressed.
- approx. 0.2 l (0.05 USgal) of water
flows into the toilet bowl.
- air flows out of the ventilation port
of the vacuum generator.
- the toilet flush valve opens and the
suction removes the water.
2. In two lavatories: In the vacuum toilet system:
- push the flush switches 51MG - the vacuum generator 37MG starts to
within 7 s. operate.
- approx. 0.2 l (0.05 USgal) of water
flows into one toilet bowl.
- air flows out of the ventilation port
of the vacuum generator.
- the toilet flush valve (of the same
toilet) opens and the suction removes
the water.
3. In a lavatory: In the vacuum toilet system:
- Operate the flush switch 51MG - the vacuum generator does not

is open. - the flush does not occur.
- on the FAP the message VACUUM SYSTEM
DISABLED-GROUND SERVICING is shown.
4. In the aircraft system: In the vacuum toilet system:
- Simulate a cabin differential - The vacuum generator remains switched
pressure of 260 mbar (3.77 off.
psi). - The flush occurs as required.
