Before You Begin
IMPORTANT! 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, provide adequate insulation to help maintain the temperature within
this range.
IMPORTANT! For installation in Mexico, the minimum water inlet pressure is 20 psi (137.9 kPa). The maximum water
inlet pressure is 80 psi (551.6 kPa).
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.
This product is only compatible with bowl model K-76395.
During installation, verify that the inlet tube connections and gaskets remain fully engaged to ensure a watertight seal.
Follow all local plumbing and building codes.
Waste Outlet Pipe Information
4" PVC
IMPORTANT! Verify 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 fit 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.
Cast Iron
A cast iron waste pipe will not be centered inside 2x4 framing, and will protrude beyond the back of the stud pocket. Use
2x6 framing or build a chase behind 2x4 framing for cast iron waste pipes.
The center of a KOHLER K-7208 cast iron waste pipe should follow the guidelines provided in the "Install Framing and
Waste Outlet" section.
