General safety instructions Dometic 4300/4400 Series Toilets
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!
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.
2.3 Warnings – all applications
Caution! Hazard of Flooding
If toilet uses raw water for ushing 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 ood 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
re 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 ttings, 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 ooding which can cause loss of
property and life.
* if connected to raw water
