Installation Guide

1. Prepare the Site
NOTICE: Measure your actual product for site preparation. Note the model number located on the bath
blower, then visit the product page at www.kohler.com for additional information.
NOTICE: Remote blower installation kit K-1446 is available for relocating the blower.
NOTICE: Provide generous, unrestricted access to the blower. You must provide access for servicing the
blower. 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 by the rim at the sides of the bath.
NOTICE: Do not support the weight of the bath by the rim.
NOTICE: Drop-in models are not intended for alcove installation. Use a flanged model for alcove
installations.
NOTE: Drop-in, alcove, 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.
NOTE: For remote blower installations, refer to the installation instructions included with the remote
blower installation kit before proceeding.
Provide adequate ventilation and at least 15 cubic feet (.4 cubic meters) of open air space for cooling
the motor and supplying sufficient air to the blower. Do not position the blower motor closer than
1″ (25 mm) to the wall or other objects.
Construct 2x4 stud framing.
Install an access panel for future blower servicing. The access panel must be at least 30″ (762 mm)
wide by 15″ (381 mm) high.
Install the rough plumbing.
Install the drain to the bath according to the drain manufacturer’s instructions.
Protect the bath surface by positioning a clean drop cloth in the basin bottom.
