Manual Flush Head with Holding Tank

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 maintenance 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 periods of time.
Winterizing the System
Read the marine head's operation and maintenance
manual for winterizing instructions.
