OVERBOARD DISCHARGE PUMP
(MACERATOR) TYPICAL
The overboard discharge pump (macerator)) can be used
to pump out the holding tank in international waters.
When the monitor panel key is energized to the full start
position, the macerator engages to pump the tank waste
overboard. Again, make sure it is legal to pump the waste overboard
before you start the operation. Also, open the waste seacock lo-
cated in the sump. The pump can be disconnected from the
2 union fi ttings that hold it for maintenance purposes.
The pump is rated for 40 minutes continuous operation.
Do not fl ush paper or feminine hygiene products into the
waste system. Keep toilet tissue usage to a minimum. Do
not use bleach or toilet cleaners in the waste system. Use
only marine approved products. Rinse and fl ush the hold-
ing tank after each pump out. This will dilute any residual
waste, and help prevent blockage and reduce odors.

TYPICAL OVERBOARD DISCHARGE PUMP
The impeller grinds up the waste as it passes through the
macerator. On the macerator shown above the system is
protected by a 10 amp breaker located at the salon main
DC distribution panel.
IN-LINE WASTE VENT FILTER
Located in the bilge near the through hull fi tting is a long
cartridge style fi lter installed in-line at the waste tank vent
hose. This fi lter removes waste odor from the system
while still permiting methane fumes to escape via the hull
side.
The waste fi lter is not seviceable. The manufacturer rec-
ommends that it be replaced each year. See the systems
chapter for additional information. Note that there are
union connectors on each end of the fi lter to aid in re-
moval.
