Outer Clip
Adjust the Shower Temperature
If the detent collar is installed: Remove the outer clip and
disengage the detent collar from the teeth of the cartridge. Do not
remove the collar; allow it to hang from the cartridge.
If the detent collar is not installed: Loosely position the detent
collar over the cartridge, ensuring the collar does not engage the
cartridge teeth.
Place the trim handle (not shown) or plaster guard (not shown)
onto the valve spline adapter.
Turn the spline adapter fully counterclockwise so the trim handle
or plaster guard can no longer move. The spline adapter is now
in the full hot position.
Remove the trim handle or plaster guard from the valve spline
adapter.
Using the volume control valve (not shown), turn on the water.
Allow the water to flow for several minutes until the water
temperature stabilizes.
Hold a thermometer in the water stream to check the water
temperature.
Once the water temperature reaches the set hot temperature limit
(section "Adjust the Hot Temperature Limit") begin slowly
rotating the detent collar and spline adapter clockwise.
