cess eliminates the need for macerators or
mechanical motors in the toilet base. When
the tank is full, the tank monitor will show full
and the vacuum pump will not run.
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 gen-
erator tank. When the switch senses a drop
in vacuum in the system, it automatically sig-
nals the pump to energize and bring the vac-
uum back to operating level. This process is
normally completed in less than two min-
utes.
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. A holding tank fluid level monitor
and macerator pump-out switch are located
in a panel near the toilet. Refer to the head
manufacturer owner’s manual for more infor-
mation on the operation of the marine head
system.
Holding Tank
Monitor tank level and have it 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 by an
approved waste dumping station through the
waste deck fitting or use the macerator dis-
charge pump, when it is legal to do so.
To operate the macerator pump, open the
ball valve at the thru-hull fitting located under
the center in-deck hatch. Turn the key on the
macerator panel and press the macerator
switch until tank is empty. Release the
switch, return the key switch to its original
position and close the discharge ball valve
when pumping is complete.
Maintenance
Clean and inspect the head for leaks regu-
larly. Periodically add chemical 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
DO NOT operate the macerator dry.
Damage to the pump can occur.
In some waters it is illegal to dis-
charge waste overboard. Remove the
seacock handle or use another
method to prevent accidental dis-
charge.
NOTICE
The head and macerator systems
must be winterized before winter lay-
up; refer to Winterizing.
