VacuFlush Pedal-Flush ToiletGeneral safety instructions
Caution! Hazard of Flooding
If the toilet uses fresh water for ushing and is connected directly or indirectly to a shore-
side 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 toilet
system 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 vacuums waste from the bowl and pumps it to a holding tank or other
efuent storage/disposal system. Operated by a foot pedal, the toilet allows the user to add water to
the bowl (before using or ushing) by slightly raising the pedal, and to ush the toilet by pressing the
pedal down. An optional 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 pedal-operated flush. Add water or ush with the foot pedal. Hands-free operation.
Home-like comfort. Toilets feature a full-size wood seat with large opening and deep bowl (500
Plus series) for premium comfort. Model 706 toilet has marine-size toilet bowl.
Water conservation. Water consumption per ush is determined by how long the pedal is pushed.
VacuFlush pedal-ush toilets typically use about 1 pint (0.5 l) per ush when the pedal is pressed
for 3 seconds.
Built-in water supply vacuum breaker. In-line vacuum breaker provides atmospheric protection
to prevent backow in event of negative pressure in the water supply line.
“OK to Flush” and “Do Not Flush” indicator lights (option). When equipped with an optional
VacuFlush status panel, a 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.
Automatic “full tank” shut-down (option). When connected to an optional holding tank level
indication system and the holding tank reaches full level, the VacuFlush toilet’s vacuum generator
will shut its electrical power off. This safety feature prevents overlling the holding tank, which
may cause damage to the boat.
