Marine Head & Holding Tank
Check with local authorities for regulations regarding the legal use of marine head systems.
FLOODING and SWAMPING HAZARD!
• Close the seawater intake seacock when leaving your boat unattended for any length of
time.
• If the seacock is left open, a hose failure could flood the bilge, swamp the batteries and the
engine, and even sink your boat.
• Before using this system, read the
marine head's operation and mainte-
nance manual.
• Look at the side of the holding tank
to check the content level.
• The dockside pump-out deck fitting
is marked WASTE.
• Empty the holding tank at every
opportunity.
Using the Marine Head
1. Open the head's seawater intake
seacock.
2. Before using the head, pump water
into the bowl to wet the sides.
3. After use, pump until the bowl is
clean.
4. Pump a few more times to clean the
lines.
5. If excess waste causes the water to
rise in the bowl, stop pumping until
the water recedes.
• Close the intake seacock when the
system will not be used for long peri-
ods of time.
Winterizing the System
Read the marine head's operation and maintenance manual for winterizing instructions.

Macerator (If Equipped)

To use the macerator to pump waste directly overboard (where regulations permit):
1. Open the overboard discharge seacock.
2. Press both macerator switches at the same time to run the pump.
3. Stop running the macerator as soon as the holding tank is empty.
4. Close the overboard discharge seacock when you are done pumping.
