In a properly operating system, the stored vacuum will “leak” down
betw
een fl ushes, causing the vacuum pump to run for a short period.
This is normal. The pump should not run for more than once every
(3) hours after the last fl ush.
To operate the Vacufl ush® head:
1. Activate the fresh water system switch at the helm
since the fresh water tank is the main water source for
the Vacufl ush® system.
2. Activate the vacuum pump switch located at the head
aft wall. This will activate the vacuum generator pump
which diminishes the size of the waste as it enters the
holding tank. Remember to tell passengers using the
toilet system to activate the vacuum pump switch be-
fore fl ushing the toilet or the waste entering the holding tank will not
be diminished in size.
3. Lift the toilet lever until the desired water level is reached. The sys-
tem requires more water for solid over liquid
waste. See fi gure 1.
4. To fl ush the toilet, press the fl ush lever
in one swift motion down to the fl oor un-
til contents in the bowl disappear. A distinct
popping noise is normal when fl ushing ac-
tion begins and the vacuum seal is broken.
Hold the lever down for at least 3 seconds.
If fl ush lever is accidentally released before
waste clears the bowl, do not try to fl ush toi-
let again until vacuum pump stops running.
A small amount of water should remain in
the bowl after fl ushing. See fi gure 2.
