10-2
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 OVER-
BOARD. VIOLATION OF THESE POLLUTION LAWS CAN RESULT IN FINES OR
IMPRISONMENT. ALWAYS KNOW THE LAW FOR THE AREAS IN WHICH YOU
BOAT. NEVER DUMP HEAD OR HOLDING TANK WASTE OVERBOARD ILLE-
GALLY.
Maintenance
The head should be cleaned and inspected for leaks regularly.
The holding tank should be pumped out and flushed as needed. 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 SYSTEM MUST BE PROPERLY WIN-
TERIZED BEFORE WINTER LAY-UP. SEE THE SECTION ON WINTERIZING.
