3 Operation

NOTICE: Failure to obey the following may
cause clogging or damage to the toilet, toilet
components, or toilet system.
• Do not operate the toilet without the water
supply turned on.
• Do not flush foreign objects. Flush only
water, bodily wastes, and rapid-dissolving
toilet tissue.
• Do not flush wet wipes, sanitary napkins,
condoms, diapers, paper cups, cotton
swabs, food, hair, or liquids such as oils or
solvents.
I
Make sure all guests understand toilet
operation before use.
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.

solids.

Do not press the Add Water switch too
long or overflow may occur.
Flushing toilet
Press the Flush switch down and hold until the
waste drains from the toilet bowl (about 10-20
seconds).
To use less water for liquid-only flushes, press
the Flush switch for a shorter period of time.

siphons water and waste from the bowl,
macerates, and propels the effluent to the
discharge line/holding tank.
