locker under the starboard aft gunwale.
The tanks should be filled until water
runs out of the vent located on the hull
side just below the fill.
9. Switch ON the freshwater pump break-
er(s) and open each faucet. When water
flows smoothly from the hot and cold
tap, close the faucet. When all faucets
are closed, the pump will shut off as
the system pressure increases. Any air
should now be purged from the system
10. Repeat if necessary.
5.3 Marine Head System
Your boat is equipped with a VacuFlush
®
marine head system. This system uses a
small amount of water and a vacuum, which
is powered by a 12-volt vacuum pump, to
flush. The toilet is connected to the pressur -
ized freshwater system. Fresh water is used
to reduce odor in the head compartment.
Before using the toilet, switch ON the VAC -
UUM PUMP and FRESH WATER PUMP
breakers on the DC distribution panel
(located in the starboard cabin upper electri-
cal cabinet)
. To use the toilet, lift the foot flush
lever slightly to wet the bowl with the desired
water level. Depress the flush lever all the
way for approximately three seconds or until
the bowl is clear. A sharp popping noise is
normal when the vacuum seal is broken and
flushing action begins. It is also normal for a
small amount of water to remain in the bowl
after flushing.
NOTICE
!
DO NOT operate the macerator dry;
damage to the pump can occur.
In some waters it is illegal to discharge
waste overboard. Remove the sea-
cock handle or use another method to
prevent accidental discharge.
The waste is directed to the holding tank,
located in the mechanical space, until it is
pumped out by a waste dumping station or
the overboard macerator discharge system.
The waste moves through a small opening in
the toilet base. Incoming air mixes with and
fragments the waste as it passes through the
base opening. This process eliminates the
need for a macerator or mechanical motors
in the toilet base. When the tank is full, the
indicators on the tank monitor (located in the
starboard cabin lower electrical cabinet) will
show full and the vacuum pump will not run.
The vacuum generator, located on top of the
holding tank in the mechanical space, con-
tains a stored vacuum and is connected to
the holding tank. The system vacuum is mon-
itored by a vacuum switch, which is located
on the vacuum generator tank. When the
switch senses a drop in vacuum pressure
in the system, it automatically signals the
pump to energize and bring the vacuum back
to operating level. This process is normally
completed in less than a couple minutes.
It is normal for the stored vacuum to leak
down slightly between flushes, causing the
vacuum pump to run for a short period. After
the last flush, the pump should not run more
than once every three hours to recharge the
system. Refer to the head owner’s manual
for more information on the operation of the
system.
Holding Tank
Monitor the holding tank level using the hold-
ing tank monitor (located in the starboard
cabin lower electrical cabinet), and have the
tank pumped out before it is completely full.
