General safety instructions
Dometic 4300/4400 Series Toilets
Caution! Hazard of Flooding
If the toilet uses fresh water for flushing 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 flooding which can cause loss of property and life .
Caution!
Overfilling 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 .
2.3
Warnings – all applications
Caution! Hazard of Flooding
If toilet uses raw water for flushing at ANY time, a raw water pump controlled by an auto-
matically operating demand switch MUST NOT be installed . If the onboard water valve or
any plumbing connections were to leak, the automatically operated pump would start and
could flood the boat . Failure to comply can cause loss of property and life .
Caution! Hazard of Shock or Fire
Always use recommended fuse, circuit breaker and wire size . Failure to do so can result in
fire that can cause the loss of property and life .
Caution! Hazard of Flooding
If toilet rim is below the waterline at ANY time (during any conditions of heel, load or trim)
and is connected to ANY through-the-hull fittings, properly positioned ventilated (vented)
loops MUST be installed in intake* or discharge piping to prevent potential back siphonage
of seawater into the boat . Failure to do so can result in flooding which can cause loss of
property and life .
* if connected to raw water
