SeaLand VacuFlush Toilet General safety instructions
Caution! Hazard of Flooding
If the toilet uses fresh water for flushing and is connected directly or indirectly to a shore-
side municipal water system at ANY time, shoreside water connections MUST be discon-
nected if the boat is unattended (even if boat is unattended for a brief period) . Failure to do
so can result in flooding 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 flooding which can cause loss of property and life.
Caution!
Overfilling 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 pos-
sibility, 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
SeaLand DTM01C tank monitor or DTM04 four-level tank monitor system.
3 Intended use
The SeaLand VacuFlush toilet provides an electric-flush toilet that vacuums waste from the bowl and
pumps it to a holding tank or other effluent storage/disposal system. Operated by a wall-mounted
flush switch, the toilet allows the user to add water to the bowl (before using or flushing) and to flush
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 flush, and when the toilet is not ready to flush due to
recharging vacuum .
3.1 Benefits
Convenient electronic flush. Add water or flush with the touch of a button.
Choice of two water consumption settings. “Normal” flush uses 1 quart (0.95 liter) per flush and
adds water to bowl after flush; “Dry Bowl” setting uses only 1 pint (0.5 liter) per flush 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 flush. Red light indicates when vacuum level is too low for a flush to
occur. Vacuum recharges in about one minute after flushing.
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 overfilling 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 flush ball open for easier
toilet cleaning or other service function .
