7 Operation
When a VacuFlush toilet is flushed, vacuum pressure created by the vacuum generator pulls
waste from the toilet to the vacuum generator . The increase of ambient pressure in the vacuum
tank causes the vacuum switch (fig . 1 D, page 2) to turn on power to the vacuum generator . The
vacuum pump begins to create vacuum and push the effluent in the discharge line to the holding
tank or other destination . After vacuum is restored in the discharge system (about 60-90 seconds,
depending on the installation), the vacuum switch shuts off electrical power, and the toilet system
is ready for the next flush.
Caution!
Vacuum pump may start automatically. Turn off electrical power before servicing .
