1. On the altitude pressure switch
43MG:
- set the altitude to 15250 ft.
(4648.11 m).
2. 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.
s. - 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.
3. In two lavatories: In the vacuum toilet system:

-push the flush switches 51MG within 15 s.
-within 10 s after the flush cycle starts, push the flush switch 51MG in the same and/or a different lavatory again.
4. On the altitude pressure switch 43MG:
-set the altitude to 16000 +700-700 ft. (4876.71 +213.35 -

5. In one lavatory:
-push the flush switch 51MG.
6. On the altitude pressure switch 43MG:
-set the altitude to 12000 ft. (3657.53 m).
7. In a different lavatory:
-push the flush switch 51MG.
-the vacuum generator 37MG starts tooperate.
-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.
-
the vacuum generator continues tooperate (first flush cycle notfinished).
-a second or additional flush cycle does not start.
-the next flush cycle sequence is prevented for approx. 15 s after the first flush cycle starts.
In the vacuum toilet system:
-the vacuum generator 37MG will not operate.
-approx. 0.2 l (0.05 USgal) of water flows into the toilet bowl.
-the toilet flush valve opens and the water drains out of the toilet bowl.
In the vacuum toilet system:
-the vacuum generator 37MG starts to operate.
-approx. 0.2 l (0.05 USgal) of water flows into the toilet bowl.
