Dometic 4300/4400 Series Toilets General safety instructions
Caution! Hazard of Flooding
If the toilet uses fresh water for ushing and is connected directly or indirectly to a
municipal water system at ANY time, water connections MUST be disconnected if the
vehicle is unattended (even if vehicle 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!
Overlling the holding tank can create serious damage to the sanitation system, such as
rupturing the holding tank and releasing tank contents. To prevent this possibility, 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
Dometic 4300 and 4400 series gravity-discharge toilets provides an electric-ush toilet that ushes
waste in to a holding tank or other efuent storage/disposal system. Operated by a wall-mounted
ush switch or electronic ush handle, the toilet allows the user to add water to the bowl (before
using or ushing) and to ush the toilet by pushing a button.
3.1 Benefits
Convenient electronic flush. Add water or ush with the touch of a button or electronic ush handle.
Residential-style wood seat with elongated opening. Provides premium quality and comfort.
Water-conserving flushes. User controls volume of water used per ush.
Manual flush override. Allows manual ushing in event of electrical power failure.
Caution! Hazard of Flooding
If toilet is connected to ANY through-the-hull ttings, ALWAYS close seacocks when
toilet is not in use (even if boat is unattended for a brief period). All passengers MUST be
instructed on how to close valves when the toilet is not in use. Failure to do so can result in
ooding which can cause loss of property and life.
