General safety instructions
SeaLand 4800 Series VacuFlush Toilet
Caution! Hazard of Flooding
If toilet is connected to ANY through-the-hull fittings, 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
flooding which can cause loss of property and life .
Caution! Hazard of Flooding
If toilet is connected to ANY through-the-hull fittings, ALL flexible hoses must be of marine
sanitation quality and must be secured to ANY fittings (such as those at seacock, vented
loop or toilet) with two stainless steel, worm-drive hose band clamps at each connection .
Connections MUST be checked frequently for integrity . Failure to comply can result in
flooding which can cause 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
Caution! Hazard of Flooding
If the toilet uses fresh water for flushing 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 flooding which can cause loss of property and life .
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 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 flooding which 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!
Overfilling 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
SeaLand DTM01C tank monitor or DTM04 four-level tank monitor system .
