13. Turn on the water supply and a wall valve to run
water through the valve.
14. Slowly rotate the CARTRIDGE STEM clockwise to
attain full cold, then rotate it counterclockwise to
attain full hot. Verify that a full range of
temperatures exists. Note: It is approximately 3/4 of
a rotation from full cold to hot.
15. With the water running, rotate the CARTRIDGE
STEM to adjust the temperature to the MAXIMUM
desired bathing temperature, verified with a
thermometer. Note: It is not recommended to
exceed 110°F.
16. With the CARTRIDGE STEM at the maximum desired
bathing temperature, slide the LIMIT STOP back
onto the CARTRIDGE STEM, making sure that it is
making contact with the LIMIT STOP PIN. Slide the
O-RING back to its original position to prevent the
LIMIT STOP from sliding off the stem; then turn off
the water.

temperature set in Step 15. If it is not the correct
temperature, repeat the calibration process.
19. Reinstall the THREADED TUBE back onto the
VALVE BODY.
20. Reinstall the TILE GUARD using the SCREWS to
