Head System

Environmental Considerations

The Environmental Protection Agency (EPA)
standards state that in freshwater lakes, reservoirs,
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 traffic subject to this
regulation, marine sanitation certified by the United
States Coast Guard (U.S.C.G.) installed on vessels
shall be designed and operated to prevent the
overboard discharge of sewage, treated or untreated
or any other waste derived from sewage.
The EPA standards further state that this shall
not be construed to prohibit the carriage of Coast
Guard certified flow through treatment devices
which have been secured so as to prevent such
discharges. They also state that the waters where
a Coast Guard certified marine sanitation device
permitting discharge is allowed include: Coastal
waters, Estuaries, The Great Lakes and Intercoastal
waterways, Freshwater lakes and Impoundments
accessible through locks and other flowing waters
that are navigable interstate by vessels subject to
this regulation. (40CFR 140.3)
NOTICE
Severe state and federal penalties are levied
for discharging raw sewage and solid waste
in waters where it is not permitted.
Demonstrating that you have disabled the
macerator by locking the system and/or
removing the seacock handle may avoid a
fine.
It is illegal for any vessel to dump plastic trash
anywhere in the ocean or navigable waters of
the United States.
NOTICE
This boat is equipped with a direct overboard
discharge valve. Discharging of sewage
directly overboard is for use where approved
only. Damage to the system could occur if
the discharge seacock is not open during

operation.

Your boat is equipped with a waste disposal system
located in the head in the forward cabin. The system
is protected by the "VACUUM FLUSH" breaker on
the DC Breaker Panel in the aft starboard side of
the forward cabin. The breaker must be ON for the
system to function (See page 4-7).
The waste system includes a Vacu-Flush
Gal. (75.7 L) holding tank with vacuum pump and
a thru-hull vent.

Vacu-Flush Head
The foot pedal at the base of
the toilet opens a mechanical
seal which allows a vacuum
to force waste through the
opening in the bowl to the
vacuum generator, through
the vacuum pump and then
to the holding tank.
Operation
• Turn ON the FRESH WATER breaker
(See page 4-7)
• Turn ON the VACUUM FLUSH breaker
(See page 4-7)
• If there is no water in the bowl, lift the foot
pedal to add sufficient water.
• To flush, depress the foot pedal until bowl is
clear.
NOTICE
NEVER use residential tissue paper in your
marine waste system.
Waste from the head is directed into the 20 gal. (75.7
L) holding tank located in the bilge. A holding tank
fluid level indicator is located on the overboard
discharge panel (See figure 3.21.1) located on the
aft wall of the vanity in the head. When the FULL
light is on, the holding tank must be emptied before
the head can be reused. However, it would be a good
practice to empty the tank when the 3/4 light is on
to avoid damage to the system.
