BEFORE INSTALLATION
Read these instructions thoroughly before beginning work.
Please leave these instructions with the customer. They contain important mainte-
nance and warranty information.
If necessary, remove the existing toilet.
CAUTION! 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 flushing
system and toilet bowl.
Prepare the support for the carrier as shown. Consult with a building contractor and/or
local codes for any additional requirements. Add a double wall studs (king and jack)
and double header per the shown dimensions. Confirm that the opening is square.
Do not loosen or tamper with the copper fittings or joint connections.
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.
