4. To flush the toilet, press the flush lever in one swift motion down to
the floor until contents in the bowl disappear. A distinct popping noise
is normal when flushing action begins and the vacuum seal is broken.
Hold the lever down for at least 3 seconds. If flush lever is accidentally
released before waste clears the bowl, do not try to flush toilet again
until vacuum pump stops running. A small amount of water should
remain in the bowl after flushing. See figure 2.
5. Do not dispose of sanitary napkins or other non-dissolving items in
the toilet. Do not attempt to flush facial tissue, wet strength tissue,
paper towels, or excessive quantities of toilet paper down the toilet.
These type items do not dissolve and cause plugging of the system.
See figure 3.
6. Make sure all passengers are aware of the
toilet operation.
7. If using a holding tank deodorant, use the
approved ones for the system.
8. See the maintenance section for cleaning and
routine inspection items such as the vent filter.
