2.1 Warnings – marine applications
The following statements must be read and understood before installing, servicing and/or

Dometic VacuFlush ToiletGeneral safety instructions
Caution! Hazard of Flooding
If the toilet uses fresh water for ushing and is connected directly or indirectly to a shoreside municipal water system at ANY time, shoreside water connections MUST be disconnected if the boat is unattended (even if boat is unattended for a brief period). Failure to do
so can result in ooding which can cause loss of property and life.
Caution! Hazard of Flooding
Before beginning any work on this product, be sure that all electrical power to the unit has
been turned off and that seacocks are in the CLOSED or OFF position. Failure to do so can
result in ooding which can cause loss of property and life.
Caution!
Overlling the holding tank can create serious damage to the sanitation system, such as
rupturing the holding tank and releasing tank contents into the bilge. To prevent this possibility, Dometic recommends using the “full” tank shut-down relay in the toilet’s electronic
control module. The “full” signal from the holding tank can be generated by an optional
Dometic DTM01C tank monitor or DTM04 four-level tank monitor system.
3 Intended use
The Dometic VacuFlush toilet provides an electric-ush toilet that vacuums waste from the bowl and
pumps it to a holding tank or other efuent storage/disposal system. Operated by a wall-mounted
ush switch, the toilet allows the user to add water to the bowl (before using or ushing) and to ush
the toilet by pushing a button. An integrated status panel activates lights to indicate when the toilet
is activated, when the toilet is ready to ush, and when the toilet is not ready to ush due to
recharging vacuum.
3.1 Benefits
Convenient electronic flush. Add water or ush with the touch of a button.
Choice of two water consumption settings. “Normal” ush uses 1 quart (0.95 liter) per ush and
adds water to bowl after ush; “Dry Bowl” setting uses only 1 pint (0.5 liter) per ush and does not
add water to the bowl – ideal for marine applications when boat is underway.
“OK to Flush” and “Do Not Flush” indicator lights. Green light indicates when proper vacuum is
achieved and toilet is ready to ush. Red light indicates when vacuum level is too low for a ush to
occur. Vacuum recharges in about one minute after ushing.
Integrated fuse. Toilet circuitry includes built-in resettable fuse. If toilet fuse ever trips, just turn
off electrical power to toilet for about 60 seconds, then turn electrical power on.
Automatic “full tank” shut-down. When connected to a holding tank level indication system and
the tank reaches full level, the VacuFlush toilet will shut its electrical power off. This safety feature
prevents overlling the holding tank, which may cause damage to the boat.
Three-second “rough seas” shut-down delay. If motion of rough sea causes “full tank” indicator
to activate toilet shut-down, a three-second signal delay occurs to allow tank contents to settle
before completing shut-down process.
Service Mode. Service switch behind toilet seat, when activated, keeps ush ball open for easier
toilet cleaning or other service function.
