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, approxi-
mately 15 seconds. The vacuum pump will run for approximately 60 to 90 seconds until system reaches
operating vacuum level and then will shut off.
WINTERIZING
At the end of each season, the SeaLand 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.
The SeaLand toilet 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.
BOWL CLEANING: For stubborn stains, use SeaLand
® Bowl and Seal
Cleaner (Fig. A). It’s manufactured especially for use with SeaLand 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
® cleanser. It is not neces-
sary to vigorously scrub with either product. Please follow label instruc-
tions.
SEAL CLEANING: After an extended time, mineral deposits from hard
water 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.
