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. When the tank is full, the tank monitor will
show full and the vacuum pump will not run.
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 head manufacturer owner’s manual for more information on the operation of the
marine head system.
HOLDING TANK
Monitor the waste level in the holding tank and have it pumped out before it is completely full. If the holding
tank is allowed to overfill, the waste will overflow out the tank vent and then overboard.
EMPTYING THE HOLDING TANK
When the holding tank is full it must either be pumped out by an approved waste dumping station through the
waste deck fitting or be pumped overboard with the macerator discharge pump, when legal to do so.
To operate the macerator pump, open the ball valve at the thru-hull fitting located in the forward bilge area.
Then activate the macerator switch, while holding the key in the "ON" position, until the tank is emptied.
Release the switch and close the discharge ball valve when pumping is complete.
THE MACERATOR DISCHARGE PUMP CAN ONLY BE RUN DRY FOR A FEW SEC-
ONDS. ALLOWING THE MACERATOR PUMP TO RUN AFTER THE HOLDING TANK
IS EMPTY MAY CAUSE DAMAGE TO THE PUMP.
IN SOME WATERS YOU CAN BE FINED FOR HAVING AN OPERABLE DIRECT
OVERBOARD DISCHARGE OF WASTE. TO AVOID A FINE, REMOVING THE
SEACOCK HANDLE, IN THE CLOSED POSITION, OR OTHER MEANS MUST BE
USED.
MAINTENANCE
The head should be cleaned and inspected for leaks regularly. Periodically add chemical to the head to help
control odor and to chemically break down the waste. See the manufacturer owner’s manual for additional
operating and maintenance information.
THE HEAD AND MACERATOR DISCHARGE SYSTEMS MUST BE PROPERLY WIN-
TERIZED BEFORE WINTER LAY-UP. SEE THE SECTION ON WINTERIZING.
