Before Installing

Read these instructions thoroughly before beginning work.
Please leave these instructions with the customer. They contain important maintenance and warranty information.
If necessary, remove the existing toilet.
Be sure to properly bleed all air from the piping system prior to using any TOTO products. Trapped/compressed air can cause damage to the fl ushing system and toilet bowl.
Framing support be should capable of suporting 880 lb load without damage to the wall. When metal framing studs are used, rigid, non-flexing bracing supports should be added to create a rigidity of the base. This will serve to minimize any flexing observed in the finished wall from sitting to standing and avoid cracks in the wall.
