7.4 During extended periods of non-use
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 liquid biodegradable laundry detergent
(should NOT contain bleach).
2. Flush toilet, holding pedal down for about two minutes. Close ush ball.
3. Turn off water supply to toilet.
4. Flush the toilet without water, allowing the vacuum pump to shut off after the ush. Repeat three
times. (This procedure will minimize any remaining water in the sanitation hoses.)
5. Turn off power to the vacuum pump.
6. Completely pump out holding tank.
If system will be subjected to freezing temperatures, please follow above procedure, then winterize
system as described in this manual.
TURN OFF ELECTRICITY AND WATER TO TOILET SYSTEM IF IDLE FOR LONG TIME
If people will not be using the boat for a long time (vacation, maintenance, off-season, etc.), or in the
event of a long electrical power interruption, electrical power and water supply to the toilet system
should be shut off.
7.5 Clearing blockage in toilet base
1. Turn off water to the toilet.
2. Open the ush ball.
3. Pull the foreign material from the 1-inch diameter orice at the bottom of the base or, using a
small diameter blunt rod, attempt to push the blockage through the orice.
7.6 Winterizing
At the end of each season, the VacuFlush toilet system should be winterized for storage. The
following procedure should be used:

2. Thoroughly ush system with fresh water.
3. Drain freshwater tank.
4. Add freshwater antifreeze to freshwater tank.
5. Flush freshwater water antifreeze and water mixture through toilet and into the waste holding
tank. Each installation is different, so amounts may vary. User discretion is required to assure
adequate protection.

owner’s manual.)
Caution
Never use automotive-type antifreeze in freshwater systems.
