NOTICE
!
DO NOT operate the macerator dry;
damage to the pump can occur.
In some waters it is illegal to discharge
waste overboard. Remove the sea-
cock handle or use another method to
prevent accidental discharge.
The vacuum generator, located behind the
shower outboard of the toilet, contains a
stored vacuum and is connected to the hold-
ing tank. The system vacuum is monitored by
a vacuum switch, which is located on the vac-
uum generator tank. When the switch senses
a drop in vacuum pressure 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 a couple minutes.
It is normal for the stored vacuum to leak
down slightly between flushes, causing the
vacuum pump to run for a short period. After
the last flush, the pump should not run more
than once every three hours to recharge the
system. Refer to the head owner’s manual
for more information on the operation of the
marine head system.
Holding Tank
Monitor the holding tank level and have the
tank pumped out before it is completely full.
If the tank is allowed to overfill, the waste will
overflow out the tank vent and overboard.
Emptying the Holding Tank
When the tank is full, pump it out at an
approved waste dumping station through the
waste deck fitting or, when it is legal to do
so, use the macerator overboard discharge
pump.
To operate the macerator overboard dis-
charge pump, open the ball valve at the thru-
hull fitting located in the mechanical space of
the aft bilge area, and activate the macerator
switch until tank is empty. Release the switch
and close the discharge ball valve when
pumping is complete.
Maintenance
Clean and inspect the head for leaks regu-
larly. Periodically add chemicals to the head
to help control odor and to chemically break
down the waste. Refer to the head owner’s
manual for additional operating and mainte-
nance information.
NOTICE
!
The head and macerator systems
must be winterized before winter
lay-up; refer to section 12, Seasonal
Maintenance.
