INTERIOR EQUIPMENT
10.1 Marine Head System
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. A special seat folds down over the toilet to make showering
more comfortable.
An opening port light above the sink provides daylight and ventilation. There is also a 12-volt
overhead light. An AC G.F.I. duplex outlet is provided by 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 (one pint to one quart) 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” breaker 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 elimi-
nates 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 moni-
tored 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 oper-
ating level. This process is normally completed in less
than two minutes.
