Before You Begin
WARNING: Risk of property or product damage. Do not use in-tank cleaners. Products containing chlorine
(calcium hypochlorite) can damage fittings in the tank. This can cause leakage and property damage.
IMPORTANT! Minimum 2x4 framing or larger is required for this installation.
IMPORTANT! The water temperature in the tank must remain between 33°F (0.5°C) and 80°F (26.6°C) to avoid freezing
and condensation. If installing on an exterior wall, adequate insulation must be used to ensure that the temperature stays
in this range.
NOTE: If 2x6 framing is used, angle the waste outlet 45 degrees in either direction.
NOTE: Do not use this product as a retrofit device for 1.28 gpf (4.8 lpf) water closets.
NOTE: Kohler Co. successfully tested this product for compatibility with KOHLER bowls K-6918, K-6299, and K-6300.
Performance may vary if this product is used with an incompatible bowl.
NOTE: The 1201721 electrical box kit is required when pairing the K-4744 cleansing seat with the bowl.
Unpack and inspect the carrier and tank for damage.
During installation, make sure that the inlet tube connections and gaskets remain fully engaged to ensure a watertight
seal.
Follow all local plumbing and building codes.
For Installations with a Cleansing Seat
CAUTION: Risk of personal injury. Connect the toilet electrical supply to a circuit protected by a dedicated
Ground-Fault Circuit-Interrupter (GFCI) or Residual Current Device (RCD).
Follow all local electrical codes.
Waste Outlet Pipe Information
4" PVC
IMPORTANT! Make sure that the height of the waste outlet pipe is sufficient so the rubber ribs on the adapter will be
fully inserted into the waste outlet pipe.
The 4" PVC waste outlet pipe is wider than the stud pocket in a 2x4 installation. This requires carving out the wall
material on both sides of the installation wall to fit the waste pipe.
The center of a 4" PVC waste outlet pipe should follow the guidelines provided in the “Install Framing and Waste Outlet”
section.
3" PVC
A PVC or flexible coupler may be wider than the stud pocket in a 2x4 installation. This requires carving out the wall
material on both sides of the installation wall to it the waste pipe.
The center of a 3" PVC waste outlet pipe should follow the guidelines provided in the “Install Framing and Waste Outlet”
section.
