Proper Cleaning; Winterizing; Clearing Discharge Lines - Dometic Sealand ECOVAC Owner's Manual

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.
BOWL CLEANING: For stubborn stains, use SeaLand
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. Restore the shine with this SeaLand cleaner. If you cannot find
it in your area, contact SeaLand for your nearest dealer. If the cleaner is not
available, you can also use Bar Keepers Friend
to vigorously scrub with either product. Please follow label instructions.
SEAL CLEANING: After an extended time, mineral deposits from hard wa-
ter can build up under the edge of the rubber bowl seal, resulting in a slow
leakdown of water from the bowl. To prevent this mineral build-up, periodically
clean under the bowl seal with SeaLand Bowl and Seal Cleaner (Fig. B).
1. Shut off water supply.
2. Apply cleaner onto the seal cleaning tool (supplied with new toilet),
open the flush ball by pressing on flush lever, and scrub under the seal.
Make sure to push bristles between bottom of seal and top of flush ball
surface to scrub all parts of seal that come into contact with flush ball.
3. Close ball and wait 2-3 minutes.
4. Open flush ball. Use brush and water to rinse away cleanser and loosened deposits.

WINTERIZING

At the end of each season, the EcoVac toilet should be winterized for
storage, by either draining or using potable water-safe antifreeze in the
system.
To drain:
1. Thoroughly flush system with fresh water.
2. Empty holding tank.
3. Shut off water supply to toilet(s), and remove inlet waterline (Fig. C).
Do not remove brass cap on bottom of valve.
4. Press flush lever until all water is drained from toilet(s).
To use antifreeze:
1. Drain potable water tank.
2. Add freshwater antifreeze to potable water tank.
3. Flush potable water antifreeze and water mixture through toilet(s) and into the waste holding tank. Each
installation is different, so amounts may vary. User discretion is required to assure adequate protection.
4. Empty holding tank.
NOTE: Use nontoxic antifreeze designated for potable water systems. (See vehicle owner's manual.)
CAUTION: Never use automotive-type antifreeze in freshwater systems.

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.
(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.
