KEY SYSTEM COMPONENTS VACUUM HOLDING TANK SYSTEM Vacuum Toilet: The EcoVac™ toilet operates in a way different from other marine toilets. EcoVac sys- tems use a small amount of water (a little more than a pint) 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. EcoVac toilets are equipped with an integral vacuum breaker which prevents the possible contamination of the potable water supply.

PROPER CLEANING – TOILET BOWL AND SEAL The EcoVac toilet should be cleaned regularly for maximum sanitation and operational efﬁciency. 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 EcoVac toilets. In certain locations where water is hard, a build-up of lime may dull the toilet bowl ﬁnish.
