CAUTION
Vacuush Marine Head System
be pumped out by an approved waste dumping
station through the waste deck tting or the op-
tional overboard discharge pump.
To pump out the holding tank with the overboard
waste discharge system, open the valve at the
discharge thru-hull tting in the forward bilge and
activate the momentary switch in the Overboard
Discharge switch panel. Monitor the uid level as
the tank is pumped and release the switch and
to turn off the discharge pump when pumping is
complete, then close the ball valve at the thru-
hull tting.
NOTICE:
Monitor the pumping operation as the over-
board discharge drains the holding tank and
turn the pump off immediately when draining
is complete.
NOTICE:
In order to comply with current State, Fed-
eral and Coast Guard regulations, the Over-
board Discharge Valve must be off and se-
cured with a lock or wire tie strap whenever
the boat is operating in areas in which the
discharge of sewage is prohibited.
IN MANY AREAS IT IS ILLEGAL TO PUMP HEAD WASTE DIRECTLY
OVERBOARD. VIOLATION OF THESE POLLUTION LAWS CAN
RESULT IN FINES OR IMPRISONMENT. ALWAYS KNOW THE LAW
FOR THE AREAS IN WHICH YOU BOAT. NEVER DUMP HEAD OR
HOLDING TANK WASTE OVERBOARD ILLEGALLY.
Manual Head System Maintenance
The head should be cleaned and inspected for
leaks regularly.
The holding tank should be pumped out and
ushed as needed. Periodically add chemical
to the holding tank to help control odor and to
chemically break down the waste. See the head
manufacturer owner’s manual for additional op-
erating and maintenance information.
NOTICE:
The head system must be properly winter-
ized before winter lay-up. Please refer to
the Seasonal Maintenance chapter and the
manufacturer owner’s manual for winter-
izing instructions.
VacuushHeadSystem(OptionalM5)
A VacuFlush marine head system is optional on M5
models. VacuFlush systems use a small amount of
water (one pint to one quart) and vacuum which is
generated by the 12-volt vacuum pump to ush.
The toilet is connected to the pressurized fresh
water system. Using fresh water results in less
odor in the head compartment and cockpit.
To use the toilet, make sure the Water System
switch in the helm switch panel is on. Then add
water to wet the bowl by lifting the foot activated
ush lever slightly until the desired water level
is reached. Flush the toilet by pressing the ush
lever all the way down for approximately three
seconds or until contents clear the bowl. A sharp
popping noise is normal when the vacuum seal
is broken and ushing action begins. It is also
normal for a small amount of water to remain in
the bowl after ushing.
The waste is transferred into the holding tank
where it remains until it is pumped out by a
waste dumping station or the optional overboard
macerator discharge system. The waste moves
through a one-inch opening in the toilet base.
Incoming air fragments the waste as it passes
through the base opening. This process eliminates
the need for macerators or mechanical motors in
the toilet base.
The vacuum generator is mounted on the hold-
ing tank and contains stored vacuum. System
