The Concerto 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 cleaner. If you cannot find our brand in your area,
contact SeaLand Product Customer Service for your nearest dealer. If it is not
available, you can also use Bar Keepers Friend ® cleanser. It is not necessary to
vigorously scrub with either product. Please follow label instructions.
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. Put Mode switch in SERVICE position. Flush ball will open automatically.
2. Apply cleanser onto the seal cleaning tool (supplied with new toilet), and
scrub under 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. Wait 2-3 minutes.
4. Pull up on flush handle or push "Add Water" switch to let water flow into bowl. Use cleaning tool and water to rinse
away cleanser and loosened deposits. You can add water for up to 15 seconds in the SERVICE position.
5. Put Mode switch in NORMAL position. Water will flow for a few seconds, then flush ball will close automatically.
Water will continue flowing into bowl, making it ready for the next flush.

PROPER CLEANING AND MAINTENANCE

MANUAL FLUSH OPERATION
In the event of an electrical failure, the flush ball of the toilet can be manually opened to clear the bowl. We recom-
mend using a long-neck screwdriver or 7/16-in. socket for the operation shown below. NEVER PRY OPEN THE
FLUSH BALL FROM INSIDE THE TOILET BOWL. Damage to the flush ball and bowl seals may result.
1. Remove access cover from top of china toilet. Place Mode
Switch in the "Manual Override" position. This disconnects
flush valve motor brake from electrical circuit.
2. Locate hole on side of china toilet. This allows access to
the flush valve motor drive arm.
3. Insert screwdriver or 7/16-in. socket through access hole
and onto hex head.
4. Turn screwdriver or socket counter-clockwise. This will
open flush ball and allow bowl contents to clear. After
bowl is clear, turn screwdriver or socket clockwise to
return flush ball to original position.
NOTES:
Water will not enter the toilet bowl during manual flush
operation.
Place Mode Switch in the "Normal" position before return-
ing to automatic operation.
