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 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. Please refer to the toilet manufacturer owner’s manual for more
information on the operation of the marine head system.
Holding Tank and Macerator Discharge Pump
The holding tank is located in the compartment on the port side of the Q-Berth behind the closeout
panel. When the tank is full, the tank monitor will show full and the vacuum pump will not run.
The tank must either be pumped out by an approved waste dumping station through the waste deck
fitting or be pumped overboard with the optional macerator discharge pump, when legal to do so.
There is no Y-valve in this system.
To operate the macerator discharge pump, open the ball valve at the overboard discharge thru-hull
fitting below the aft berth. Then activate the momentary macerator switch located in the holding
tank monitor panel in the head compartment, until the tank is emptied. Release the switch and close
the discharge ball valve when pumping is complete.
Note: The macerator discharge pump can only be run dry for a couple of seconds. Allowing
the macerator pump to run after the holding tank is empty will cause damage to the
pump.
IN MANY AREAS IT IS ILLEGAL TO FLUSH HEAD WASTE DIRECTLY
OVERBOARD. VIOLATION OF THESE POLLUTION LAWS CAN RESULT
IN FINES OR IMPRISONMENT. ALWAYS KNOW THE LAW FOR THE AR-
EAS IN WHICH YOU BOAT. NEVER DUMP HEAD OR HOLDING TANK
WASTE OVERBOARD ILLEGALLY.
