TO WASTE PUMP-
OUT FITTING ON DECK
• Read the marine head operation and maintenance manual (included in your owner's packet).
• The holding tank is plumbed to a waste fitting on the deck for dockside pump-out.
• Check the content level of the holding tank by looking at the side of the tank.
• Empty the holding tank at every opportunity.
Using The Manual Flush Marine Head:
1. Open the head's seawater intake valve (seacock).
2. Before using the head, pump enough water into the bowl to wet the sides.
3. After use, pump until the bowl is thoroughly cleaned. Continue pumping a few more times to clean the lines.
4. If excess waste causes the water to rise in the bowl, stop pumping until the water recedes.
Winterizing The Marine Head
1. Shut off the intake seacock and pump until the bowl is dry.
2. Remove the drain plug in the base and pump again to remove all of the water.
• Do not fill the bowl with anti-freeze.
• Close the intake seacock while the boat is underway or whenever the boat is left moored in the water.
