Air locks can occur in the cooling pump water
supply at the time of launching. If your boat
has been recently launched and water is not
flowing from the overboard thru-hull when the
COOLING PUMP breaker on the AC MDP is
ON, air may have to be purged from the sys-
tem. This can be achieved by making sure
the valve at the cooling pump intake thru-hull
is open. Then run the boat at cruise speed
for several minutes. A scoop attached to the
intake thru-hull will pressurize the system and
force the air through the pump. Refer to the
air conditioner owner’s manual for additional
operating and maintenance information.
NOTICE
!
Air conditioners use surface water to
cool. DO NOT operate the air condi-
tioner out of the water or without the
raw water supply, or damage to the
system will occur. Make sure there is
a water supply before operating the air
condition. The lack of a water supply
can also trip the circuit breaker.
8.5 Head Compartment
The head compartment is equipped with
a fresh water sink with a hot and cold fau-
cet and shower. When the FRESH WATER
switch in the DC MDP is on, the water system
will operate much like a home water system.
Refer to section 5, Plumbing Systems, for
more information on operating the system.
For care and cleaning information, refer to
section 11, Routine Maintenance.
Secure the head compartment door in the
closed position whenever the boat is under-
way to prevent damage to the door.
An AC GFI duplex outlet is provided in the
head. It is installed in a waterproof outlet box
with an opening cover. Close the cover com-
pletely when the outlet is not being used, to
prevent corrosion.
The countertop may be made of Corian ® .
Refer to section 11, Routine Maintenance, for
Corian care information.
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 generated by the 12-volt vacuum pump, to
flush. The toilet is connected to the pressur -
ized fresh water system. Fresh water is used
to reduce odor in the head compartment.
Before using the toilet, ensure the VacuFlush
breaker on the DC MDP is ON. 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.
The waste is directed to the holding tank,
located outboard of the starboard hull
stringer in the aft 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 indi-
cators on the tank monitor (located just above
the toilet in the outboard panel of the head
wall) will show full and the vacuum pump will
not run.
