Macerator Toilet
• Before beginning any work on this product,
be sure that all electrical power to the unit
has been turned off and that the seacocks are
in the closed or off position.
NOTICE: Overfilling the holding tank can cause
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 a full
tank shut-down relay. The full signal from the
holding tank can be generated by an optional
Dometic DTM01C tank monitor or DTM04 four-
level tank monitor system.
I
Follow all local regulations for waste tank
discharge.

2 Intended use

The Macerator toilet (hereinafter referred to
as toilet or product) provides an electric-flush
toilet that macerates waste and pumps it either
to a holding tank or other effluent storage/
disposal system, or overboard. Operated by a

add water to the bowl (before or after flushing)
and to flush the toilet by pushing a button. This
toilet is designed for use in marine applications
and is only suitable for the intended purpose
and application in accordance with these
instructions.

3.2 Toilet tissue paper
To avoid potential clogging problems with some
household toilet tissues, Dometic recommends
using quick-dissolving tissue, such as Dometic
rapid dissolving 1-ply or 2-ply toilet tissue.
I
Not every marine-grade toilet tissue
paper dissolves rapidly.
To determine any toilet tissue's ability to
dissolve, immerse one square of the tissue in
a jar of water and shake 5-10 times. The tissue
sample should break up so that it is no longer in
one piece.
3.3 Benefits
Convenient electronic flush. Add water
(freshwater version only) or flush with the touch
of a button.
