Troubleshooting - Kohler K-2975 Installation Manual

Adjust the Shower Temperature (cont.)
NOTE: While rotating the detent collar, small in-and-out
adjustments will be required to ensure the collar does not engage
the cartridge teeth. Use the detent collar to rotate the spline adapter.
While rotating the collar and spline adapter, monitor the water
outlet temperature.
When the temperature reaches 104-105°F (40-40.5°C), push the
detent collar in until it engages the teeth of the cartridge.
With the clip tab positioned toward the valve, reinstall the clip to
the head nut.
Using the volume control valve (not shown), turn off the water.
