VacuFlush toilet – general use
Toilet system start-up
1. Fill freshwater tank.
2. Turn on electrical power and water supply to toilet system. When the system
vacuum reaches operating level, the vacuum pump will shut off, and the toilet
is ready for use.
Normal toilet operation
ADD WATER TO TOILET BOWL
Raise ush pedal until desired water level is reached. More water is
usually added only when ushing solids. (If pedal is raised too long,
water may overow the toilet bowl.)
FLUSH TOILET
Press foot pedal sharply down until contents clear bowl. Hold foot
pedal down for three seconds. After ush, let foot pedal snap back
into position. If foot pedal is accidentally released before waste
clears bowl, do not ush again until vacuum pump stops running. A
small amount of water remains in bowl after ushing.
VacuFlush®Toilet System Quick-Start Guide
DO NOT FLUSH FOREIGN OBJECTS
CAUTION! Flush only water, bodily wastes and rapid-
dissolving tissue paper. Do not flush wet wipes, sanitary
napkins, condoms, diapers, razor blades, paper cups,
cotton swabs, food, hair or liquids such as oils or solvents.
Clogging or damage to the toilet system may occur.
Note
Make sure all guests understand toilet operation before use.
Use RAPID-DISSOLVING toilet tissue – avoid clogs
To avoid potential clogging problems with some household
tissues, Dometic recommends the use of quick-dissolving
tissue, such as Dometic Rapid-dissolving 1-ply or 2-ply
Toilet Tissue.
IMPORTANT! NOT EVERY MARINE-GRADE TOILET PAPER
DISSOLVES RAPIDLY
To determine any tissue’s ability to dissolve, immerse one square
of tissue in a jar of water and shake 5-10 times. The tissue sample should break up
so that it is no longer in one piece.

VacuFlush®5140 series vacuum toilets include a hold-open pedal lock. It holds
the ush ball open to allow positive air pressure into the holding tank during
pump-out. This helps assure thorough discharge of the tank.
1. Turn off water supply to toilet and
electrical power to vacuum pump.
2. a. Press down fully on Pedal, then
b. press Lock.
3. Slowly bring Pedal up while holding
Lock down against Pedal until Pedal
stops. Lock prevents ush ball inside
the toilet bowl from closing.
4. Open ball valve on top of VHT or at
seacock (if applicable). Start Discharge
Pump at control panel and pump out
holding tank. Let pump run for 4-5
minutes or until empty.
5. After pump-out is complete, press
down on Pedal fully, then release to
close ush ball.
6. Close ball valve at top of VHT and at seacock (if applicable).
