Raw Water System - Formula Cruiser Owner's Manual

SYSTEM OPERATION AND EQUIPMENT
Jabsco Manual Head—This system, as the
name indicates, is operated manually without the
need for 12 volt power. The toilet's water supply
comes from raw (sea) water, and the vacuum
necessary to flush waste from the toilet to the
waste holding tank is generated with a manual
pump attached to the toilet assembly.
To operate this head system, the raw water
seacock associated with the manual toilet must be
OPEN. Select the "wet" bowl position on the
wet/dry bowl selector and pump the handle a few
times to add water to the bowl prior to use.
Flushing the toilet is accomplished by pumping
the handle (with bowl selector in "wet" position)
until the bowl is thoroughly rinsed and evacuated.
When finished, move the wet/dry bowl selector to
the "dry" position, and continue pumping until
about one cup of water remains in the bowl.
Leave the wet/dry selector in the "dry" position
when toilet is not in use.

VacuFlush head—The VacuFlush system is
active when the 12VDC system is energized and
the HEAD PUMP breaker is turned ON. The head
pump creates vacuum in the system, and when
the toilet is flushed the stored vacuum clears the
bowl of waste. The vacuum pump will run for a few
minutes after flushing to restore vacuum in the
system and then automatically shut off upon
reaching the set vacuum level.
The water pump breaker on the 12VDC panel
must be turned ON (not necessary if boat is
connected to dockside water supply). This
provides the water needed for flushing.
Monitor your waste tank level indicator to know
when your tank has reached its full level and it's
time to have it pumped out.
FORMULA
Please note: Your head system is equipped
with a safety mechanism that shuts down the
head pump, not allowing the toilet to flush,
when the waste tank full level light has
illuminated. This safety measure prevents the
waste holding tank from being overfilled.
After pumping out your waste holding tank,
recharge the holding tank with the approved
waste treatment chemical as prescribed in the
Sealand Operation Manual found in your boat's
systems information binder.
Macerator—The optional macerator system
allows the discharging of wastewater directly
overboard through a seacock/underwater through-
hull fitting. Before operating the macerator make
sure the macerator seacock is open. Activate the
macerator by depressing and holding the
macerator switch located in the head
compartment until the tank has reached the
empty level.
Overboard discharge of waste water
should only be used in approved areas. It
is your responsibility to comply with local
regulations regarding the discharge of
waste. You could be fined if your boat has
an operable overboard discharge system.
Removing the handle of the seacock while
in closed position, or disabling the system
by other means may be required to avoid
a fine.

RAW WATER SYSTEM

Your Formula boat may have as many as two
accessory components (generator and air
conditioning) - in addition to the engines - with
complete raw water systems.
Each raw water system will have its own thru-hull
water intake, seacock and strainer. The seacock is
very important. It protects the boat from sinking if
a hose or fitting should fail. It is important to close
any seacock not in use.
Waste water from the generator is routed with the
generator's exhaust system. Waste water from the
air conditioning unit is directed overboard through
a drain port in the hull.
Your engines have their own raw water system for
cooling. Refer to the propulsion unit operator's
manual for engine cooling information.
