Holding Tank and Macerator Discharge Pump
The holding tank is located in the compartment behind
the center bow storage hatch. 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 behind the center bilge access hatch in the head compartment. Then activate the
momentary macerator switch located in the holding tank monitor panel 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.
