Holding Tank and Optional Macerator Dis-
charge Pump
The holding tank and vacuum generator are lo-
cated in the engine compartment. The macerator
pump is located near the holding tank and dis-
charges waste to a thru-hull fitting in the bilge.
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 in
the stern or be pumped overboard with the op-
tional macerator discharge pump, when legal to
do so.
To operate the macerator dis-
charge pump, open the
seacock at the overboard dis-
charge thru-hull fitting located
in the engine compartment.
Then activate the momentary
macerator switch located in
the switch panel in the head
compartment and monitor the
fluid level until the tank is emp-
tied. Release the switch and close the discharge
seacock when pumping is complete.
Note: The macerator discharge pump can only
be run dry for a couple of seconds. Al-
lowing the macerator pump to run af-
ter the holding tank is empty will cause
damage to the pump.
Note: The overboard macerator discharge
pump option for the waste holding tank
is not available with the grey water sys-
tem.
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 AREAS IN WHICH YOU BOAT.
NEVER DUMP HEAD OR HOLDING TANK WASTE
OVERBOARD ILLEGALLY.
Maintenance
The head should be cleaned and inspected for
leaks regularly. Monitor the cycle time of the
vacuum pump. If it cycles more than once every
two or three hours or runs longer than three min-
utes after a flush, there may be a leak in the
system or the vacuum pump may require service.
Always make sure to leave enough water in the
bowl to cover the flush valve and bowl seal. Pe-
riodically, lubricate the seal with teflon grease.
This will help keep the seal soft and pliable.
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. The macerator pump should be sprayed
with a metal protector periodically to reduce cor-
rosion. See the head manufacturer owner’s manual
for additional operating and maintenance informa-
tion.
The vent hose for the holding tank is equipped
with a charcoal filter to reduce odor from the hold-
ing tank. The filter should be changed once a
year or if the holding tank has become overfilled,
which will plug the filter and could cause damage
to the waste system.
Note: The head system must be properly win-
terized before winter lay-up. See the
manufacturer owner’s manual for ad-
ditional operating and maintenance in-
formation.
10.2 Galley and Sink
The galley is equipped with storage and a fresh
water sink with hot and cold faucets. Water is
supplied to the sink by a 12-volt pump located in
the engine room. When activated by the Water
Pump breaker in the cabin DC panel, the water
system will operate much like the water system in
a home. An automatic pressure sensor keeps the
system pressurized. The sink drains overboard or
to the optional grey water holding system through
the cabin sink drain system. See the Fresh Water
System chapter for more information on operating
the fresh water system.
