INTERIOR EQUIPMENT
10.1 Head Compartment and Marine Toilet
The head compartment is equipped with a sink, hot and cold faucet that converts to a shower by pulling the
faucet out of the base.
Storage is in the vanity over the counter top and behind the door under the sink. Daylight and ventilation is
provided by an opening port light above the sink. There is also a 12-volt overhead light. An AC G.F.I. duplex
outlet is provided next to the door below the sink.
Marine Head System
Your boat is equipped with a VacuFlush marine head system as standard
equipment. VacuFlush systems use a small amount of water and vacuum
which is generated by the 12-volt vacuum pump to flush. The toilet is
connected to the pressurized fresh water system. Using fresh water results
in less odor in the head compartment.
To use the toilet, make sure the “Electric Head” switch on the cabin DC
breaker panel is on. Then add water to wet the bowl by depressing the foot
activated flush lever slightly until the desired water level is reached. Flush
the toilet by activating the flush lever all the way for approximately three seconds or until contents clear the
bowl. 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 transferred into the holding tank where it remains until it is pumped out by a waste dumping station
or the 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 holding tank and contains stored vacuum. System vacuum is
monitored by a vacuum switch which is located on the vacuum
generator tank. When the switch senses a drop in vacuum 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 two minutes.
It is normal for the stored vacuum to leak down slightly between
flushes, causing the vacuum pump to run for a short period. The
pump should not run more than once every three hours after the
last flush for recharging the system. A holding tank fluid level
monitor and macerator pump-out switch is located in a panel near
the toilet. Please refer to the toilet manufacturer owner's manual
for more information on the operation of the marine head system.
