KEY SYSTEM COMPONENTS Vacuum Toilet: The VacuFlush toilet operates differently as compared to other toilets. VacuFlush systems use a small amount of water (from as little as 400 ml) per flush in addition to a powerful vacuum. The toilet is connected to a pressurized freshwater system. Because a vacuum generator is located between the vacuum toilet and the waste holding tank, the result is an odor-free bathroom compartment.
KEY SYSTEM COMPONENTS (cont'd) SaniGard™ Holding Tank Vent Filter: The vent SaniGard Vent Filter filter stops odors that escape from the holding tank vent. It contains odor-removing filter media to keep your boat smelling clean and pleasant. Each cartridge is good for an entire season and is easily replaced for a fresh start.
VACUUM TOILET OPERATION 1. To add water to the toilet before using, raise flush lever until desired water level is reached. Generally, more water is required only when flushing solids. 2. To flush toilet, press flush lever sharply down to the floor until contents clear bowl. A sharp popping noise is normal when the vacuum seal is broken and flushing action begins. Be sure to hold lever down for three seconds.
PROPER TOILET CLEANING AND MAINTENANCE Dometic china toilets should be cleaned regularly for maximum sanitation and operational efficiency. You can clean it just as you would a household toilet. Do not use caustic chemicals, such as drain-opening types, as they will damage the seals. Fig. A BOWL CLEANING: For stubborn stains, use SeaLand® Bowl and Seal Cleaner (Fig. A). It’s manufactured especially for use with Dometic toilets.
MAINTENANCE SCHEDULE Maintenance intervals and normal parts replacement vary widely depending on numerous factors such as frequency of system use, quality of flushing water, etc. The following chart is intended strictly as a general guide in keeping the sanitation system 100% ready for any conditions of use.
