DO NOT FLUSH FOREIGN OBJECTS
CAUTION! Flush only water, bodily wastes and rapid-dissolving tissue
paper. Do not flush wet wipes, sanitary napkins, condoms, diapers,
razor blades, paper cups, cotton swabs, food, hair or liquids such as
oils or solvents. Clogging or damage to the toilet system may occur.
Note
Make sure all guests understand toilet operation before use.
Use RAPID-DISSOLVING toilet tissue – avoid clogs
To avoid potential clogging problems with some household tissues,
Dometic recommends the use of quick-dissolving tissue, such as
Dometic rapid-dissolving 1-ply or 2-ply toilet tissue.
IMPORTANT! NOT EVERY MARINE-GRADE TOILET
PAPER DISSOLVES RAPIDLY
To determine any tissue’s ability to dissolve, immerse one square of
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.
