Marine Sanitation Regulations All boats with fixed toilets in U.S. waters and in the waters of some other countries are required to be equipped with an operable marine sanitation device (MSD). The VacuFlush system is a holding tank or Type III system as defined by the U.S. Coast Guard. Type III systems are designed to permit operation of the toilet without the direct discharge of untreated waste after every flush.
Key System Components Vacuum Toilet: The VacuFlush toilet operates in a way different from other marine toilets. VacuFlush systems use a small amount of water (a little more than a pint or .5 liter) per flush in addition to a simple vacuum. The toilet is connected to a pressurized freshwater system. Fresh water is the key to an odor-free bathroom compartment. VacuFlush toilets are equipped with an integral vacuum breaker which prevents the possible contamination of the potable water supply.
System Start-Up 1. Turn on inlet water supply. 2. Turn on electrical power to system. 3. Flush water into system by depressing flush lever until water starts flowing to the vacuum pump, approximately 15 seconds. The vacuum pump will run for approximately 60 to 90 seconds until system reaches operating vacuum level and then will shut off. Proper Bowl Cleaning For stubborn stains, use SeaLand® Toilet Bowl Cleaner (Fig. A). It’s manufactured especially for use with SeaLand toilets.
Clearing Discharge Lines Sanitation hoses should be cleared if toilet will not be needed for an extended period of time (more than two weeks). 1. Fill toilet bowl with water and add 4 oz. (120 ml) of biodegradable laundry detergent (should not contain bleach). 2. Flush toilet, holding pedal down for about two minutes. Close flush ball. 3. Turn off water supply to toilet. 4. Flush the toilet without water, allowing the vacuum pump to shut off after the flush. Repeat three times.
VacuFlush Maintenance Kit The VacuFlush Maintenance Kit contains replacement parts used in routine maintenance of VacuFlush toilets. A “must” for those who cruise to remote locations. The kit includes vacuum tester, water valve, seal kit, duckbill valves (4) and an owner’s manual in a convenient storage container. VacuFlush Maintenance Kit (item number 310228) Ordering Parts Dometic is ready to assist you in the event service is required. Before calling, please have the following information available.
Deodorants and Special Tissue Your VacuFlush sanitation system requires the regular addition of a deodorant product to reduce malodors and to help break down holding tank contents. Several factors should be considered in selecting a deodorant product. Liquid or Granulated: Liquid products obviously work more quickly by readily going into solution.
Accessories NozAllTM Pumpout Adapter: The NozAll pumpout adapter provides an airtight seal between your boat’s deck waste fitting and the pumpout station nozzle. Just screw your personal NozAll adapter into your deck fitting, and be assured of an airtight connection for pumping out holding tank contents. Each item contains a glass-filled nylon NozAll adapter, gasket and vinyl cap. Item number 343502 (1-1/2"11.5 tpi), 343503 (1-1/4"-11.5tpi), or 343504 (1-1/4"-16tpi).
