Interior Equipment
vacuum is monitored by a vacuum switch which
is located on the vacuum generator tank. When
the switch senses a drop in vacuum 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 two
minutes.
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 is located in the head compartment just
above the vanity counter top. Refer to the toilet
manufacturer owner's manual for more informa-
tion on the operation of the VacuFlush marine
head system.
VacuFlush Holding Tank and Optional Mac-
erator Discharge Pump
The VacuFlush holding tank and vacuum generator
are located in the bilge below the cockpit. If the
optional overboard macerator discharge pump is
installed on your boat, it is located on the holding
tank and discharges waste to a thru-hull fitting in
the forward bilge below the access hatch in the
in-floor storage compartment.
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 deck or be pumped overboard with the optional
macerator discharge pump, when legal to do so.
To operate the macerator discharge pump, open
the seacock at the overboard discharge thru-hull
fitting and activate the momentary macerator
switch in the head compartment. Monitor the fluid
level until the tank is emptied. Release the switch
and close the discharge seacock when pumping
is complete.
NOTICE:
Monitor the pumping operation as the over-
board discharge drains the holding tank and
turn the pump off immediately when draining
is complete.

NOTICE:
In order to comply with current State, Fed-
eral and Coast Guard regulations, the Over-
board Discharge Valve must be off and se-
cured with a lock or wire tie strap whenever
the boat is operating in areas in which the
discharge of sewage is prohibited.
CAUTION
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.
VacuFlush Head System 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 ev-
ery two or three hours or runs longer than three
minutes 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.
to the head to help control odor and to chemi-
cally break down the waste. The macerator and
vacuum pumps should be sprayed with a metal
protector periodically to reduce corrosion. See the
head manufacturer owner's manual for additional
operating and maintenance information.
The vent hose for the holding tank is equipped with
a charcoal filter to reduce odor from the holding
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.
NOTICE:
The head system must be properly winterized
before winter lay-up. See the manufacturer
owner's manual for additional operating and
maintenance information.
