* Important Notes:
1. When you place the seat (5) to the seat holder (6), make sure that the gloss side
faces inward (toward the sphere). Use light to identify the gloss finish. The flat
side faces outward, not touching the sphere.
2. To distinguish the end seal (7) from the regular seal (4), compare the thickness of
each. The seal that is thicker than the other is the end seal.
