1. Prepare the Site
WARNING: Risk of personal injury. This cast iron bath is extremely heavy. Obtain sufficient help
to carefully lift and move it.
NOTICE: Measure your product for site preparation. Note the model number located on the blower, then
visit the product page at www.kohler.com for more information.
NOTICE: Provide adequate ventilation and a minimum 15 cubic feet (.4 cubic meters) air space in the
installed location for cooling the motor and to supply sufficient air for the blower. Do not install the
blower motor closer than 1″ (25 mm) from the wall or other objects.
NOTICE: Provide generous, unrestricted access to the blower. You must provide access for servicing the
blower and controls. The access must be located immediately next to the blower.
NOTICE: Do not lift the bath by the piping or blower, or use the piping or blower for structural support
of the bath. To avoid damage to the bath, lift at the sides of the bath.
NOTICE: Do not support the weight of the bath by the rim. Allow for a 1/16″ (2 mm) gap between the
finished material and the underside of the bath rim.
NOTICE: Ensure adequate clearance for faucets and valves.
NOTICE: Allow at least 2″ (51 mm) clearance between the edge of the bath rim and the finished wall.
NOTICE: For under-mount installation, go to www.kohler.com for information on the optional
under-mount kit for your bath model. Follow the installation instructions included with the under-mount
kit.
NOTE: Drop-in, alcove, under-mount, or corner installation is possible, depending on the product chosen.
Carefully unpack and inspect the new bath for damage before installation. If there is damage do not
install the bath; contact your dealer.
Make sure the flooring offers adequate support for your bath, and verify that the subfloor is flat and
level.
