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 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
Dometic DTM01C tank monitor or DTM04 four-level tank monitor system.
3 Intended use
The SeaLand MasterFlush toilet provides an electric-ush toilet that macerates waste 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. The Dometic ush switch panel includes lights to indicate when electric
power to the toilet is activated, and when the holding tank (if applicable) is full.
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 0.85 gal. (3.2 liters) per ush and adds
water to bowl after ush; “Dry Bowl” setting uses only 0.45 gal. (1.7 liters) per ush and does not add
water to the bowl.
Versatile installation. Powerful macerator pump allows toilet to be located up to 98 ft. (30 m) away and
9.8 ft. (3 m) below holding tank or other discharge line destination.
“Power on”, “3/4” and “full tank” indicator lights. Dometic ush switch panel indicates when
electrical power to toilet is activated, and when holding tank is 75% and/or 100% full (depending on
holding tank level indication system).
Automatic “full tank” shut-down. When connected to a holding tank level indication system, the
MasterFlush toilet control module will shut off electrical power to the toilet when the holding tank is full.
This safety features prevents overlling the holding tank, which may cause damage to the boat.
