able as an option. The owner’s packet in your boat
contains information pertaining to your head system
that should be read carefully.
Vessel Operators Requirements
The Environmental Protection Agency (EPA) Marine
Sanitation Device Standards state that in freshwater
lakes, freshwater reservoirs or other freshwater
impoundments whose inlets or outlets are such as
to prevent the ingress or egress by vessel traffic
subject to this regulation, or in rivers not capable of
navigation by interstate vessel traffic subject to this
regulation, marine sanitation devices certified by the
U.S. Coast Guard installed on all vessels shall be
designed and operated to prevent the overboard
discharge of sewage, treated or untreated, or of any
waste derived from sewage. The Agency further
states that this shall not be construed to prohibit the
carriage of Coast Guard-certified flow through treat-
ment devices which have been secured so as to
prevent such discharges.
Note: There is the possibility of being fined for
having an operable overboard discharge in the
U.S. waters. Removing handle of seacock while
in closed position, or other means must be uti-
lized to avoid fine.
It is illegal for a vessel to dump plastic trash
anywhere in the ocean or navigable waters of
the United States.
It is also stated that in all other waters, the Coast
Guard-certified marine sanitation device installed on
all vessels shall be designed and operated to retain,
dispose of, or discharge sewage. Waters where a
Coast Guard-certified marine sanitation device per-
mitting discharge is allowed include coastal waters
and estuaries, the Great Lakes and inter-connected
waterways, fresh-water lakes and impoundments
accessible through locks, and other flowing waters
that are navigable interstate by vessels subject to
this regulation. (40 CFR 140.3).
VacuFlush® Head
The VacuFlush® head utilizes the HEAD breakers
on the DC distribution panel in the salon. Individual
breakers on the DC distribution panel control the
GUEST HEAD and MASTER HEAD. The foot pedal
at the base of the toilet opens a mechanical seal
and vacuum forces waste through the opening in the
bowl to the vacuum generator, through the vacuum
pump and then to the holding tank. (Figure 8.7)
To Operate Vacu-Flush® Head:
1. Turn ON the FRESH WATER PUMP breaker.
2. Turn ON the HEAD SYSTEM breaker.
3. If no water is present in bowl or to add water to
bowl before using, raise flush handle until
desired water level is reached. (Water flow will
stop automatically after a period of time.).
4. To flush, press flush handle down. Water will
flow into bowl for two seconds, and then flush
ball will open. Toilet will not flush again until “OK
to Flush” light is on.
HOLDING TANK OPERATION
Waste from the head is directed into the 42 gallon
(159 liter) holding tank in the starboard forward
bilge. Holding tank fluid level indicators are located
on the distribution panel area in the salon and in the
head. The head indicators read OK TO FLUSH and
DO NOT FLUSH (Figure 8.8). When the DO NOT
FLUSH light is on, the holding tank must be emptied
before the head can be reused. It is a good practice
to empty the holding tank when the 1/2 light (on the
DC Distribution panel) is on to avoid overflowing the
holding tank and ruining the vent filter.

C AUTION: Do not dispose of sanitary napkins
or other non-dissolving items in toilet, such as
facial tissue or paper towels. These items can
cause plugging of the sanitation system.
