SeaLand 4700 Series VacuFlush Toilet General safety instructions
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
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!
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
Dometic DTM01C tank monitor or DTM04 four-level tank monitor system .
3 Intended use
The SeaLand 4700 series VacuFlush toilet provides an electric-flush toilet that vacuums waste from
the bowl and pumps it to a holding tank or other effluent storage/disposal system . Operated by a
wall-mounted flush switch or electronic flush handle, the toilet allows the user to add water to the
bowl (before using or flushing) and to flush the toilet . A status panel activates lights to indicate when
the toilet is ready to flush, when the toilet is operating, and when the toilet is not ready to flush due
to recharging vacuum or a full holding tank .
3.1 Benefits
Convenient electronic flush. Add water or flush with the touch of a button or by operating the
flush handle . No need to continue pressing button or handle for full flush to occur .
Choice of two water consumption settings. “Normal” flush uses 2 quarts (1 .9 liters) per flush and
adds water to bowl after flush; “Dry Bowl” setting uses only 1 pint (0 .5 liter) per flush and does not
add water to the bowl – ideal for marine applications when boat is underway .
“OK to Flush” and “Do Not Flush” indicator lights. Green light indicates “OK to Flush” when
proper vacuum is achieved and toilet is ready to flush . Red light indicates “Do Not Flush” when
vacuum level is too low for a flush to occur . Vacuum recharges in about one minute after flushing .
Integrated fuse. Toilet circuitry includes built-in resettable fuse . If toilet fuse ever trips, just turn
off electrical power to toilet for about 60 seconds, then turn electrical power on .
Automatic “full tank” shut-down. When connected to a holding tank level indication system and
the tank reaches full level, electrical power to the toilet will become interrupted and the red “Do
Not Flush” light will turn on . This safety feature prevents overfilling the holding tank, which may
cause damage to the boat or vehicle .
Three-second “rough seas” shut-down delay. If motion of rough sea causes “full tank” indica-
tor to activate toilet shut-down, a three-second signal delay allows tank contents to settle before
completing shut-down process .
Service mode. Service mode keeps flush ball open for easier toilet cleaning or other service
function .
