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
Dometic DTM01C tank monitor or DTM04 four-level tank monitor system .
3 Intended use
The SeaLand MasterFlush toilet provides an electric-flush toilet that macerates waste 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 . The Dometic flush 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 flush with the touch of a button .
Choice of two water consumption settings. “Normal” flush uses 0 .85 gal . (3 .2 liters) per flush and adds
water to bowl after flush; “Dry Bowl” setting uses only 0 .45 gal . (1 .7 liters) per flush 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 flush 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 overfilling the holding tank, which may cause damage to the boat .
