Caution! Hazard of Flooding
If the toilet uses fresh water for ushing and is connected directly or indirectly to a shore-
side municipal water system at ANY time, shoreside water connections MUST be discon-
nected if the boat is unattended (even if boat is unattended for a brief period). Failure to do
so can result in ooding which can cause loss of property and life.
Caution! Hazard of Flooding
Before beginning any work on this product, be sure that all electrical power to the unit has
been turned off and that seacocks are in the CLOSED or OFF position. Failure to do so can
result in ooding which can cause loss of property and life.
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 DNF (Do Not Flush) full tank monitor or DTM04 four-level tank monitor system.
3 Intended use
SeaLand 9300 and 9400 series RushFlush toilets provide an electric-ush toilet that uses a high-
velocity water jet to break up efuent waste and push it to a holding tank or other efuent storage/
disposal system. Operated by an electronic ush handle or wall-mounted ush switch (depending on
model), 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 3/4-full or completely full.
RushFlush toilets are not intended for use with a raw water or seawater flush system.
3.1 Benefits
Convenient electronic flush. Add water or ush with the touch of a button or electronic ush handle.
Adjustable water consumption settings. To optimize toilet performance and overall system operation,
the rate of water ow can be adjusted separately for the upper rim of the toilet and for the lower bowl
jet. This allows water consumption to range from as little as 1.25 gallon (4.7 l) up to 2.75 gallons (10.4 l)
per ush. The water ow control module is located inside the back of the toilet, so adjustment should be
made during installation.
“Power on”, “3/4-full” and “full tank” indicator lights. Dometic ush switch panel indicates when
electrical power to toilet is activated, and when holding tank is 3/4 and completely full (when
connected to holding tank level indication system).
Automatic “full tank” shut-down. When connected to a holding tank level indication system, the
RushFlush 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.
