area, contact Dometic for your nearest dealer. If
the cleaner is not available, use a non-abrasive
bathroom and toilet bowl cleaner. Follow label
instructions.
For stubborn stains on model 300 and 301 toilet
bowls, carefully use rubbing alcohol to wipe and
remove the stain.
5.4 Cleaning the Flush Ball and Seal
Aer a period of time, mineral deposits from
hard water may build up on the flush ball or seal,
resulting in a slow water leak. To prevent this,
periodically clean the flush ball and seal.

Flush Pedal
1. Remove minor debris from the flush ball and
seal by slowly depressing and releasing the
flush pedal several times. This will loosen
and rinse debris from the surfaces. Repeat
several times for stubborn buildup.
2. If step 1 does not fully clean the ball and seal,
clean with a so bristle brush and SeaLand
toilet bowl cleaner.
– Fully clean the top of the flush ball and
under the seal where it contacts the flush
ball.
