increases the risk of accidental scalding. Water temperatures at

or death. Before you decide to change the temperature setting,
read the following charts carefully.

To prevent burns:
Use the lowest operating temperature setting necessary to
provide comfortably-hot water.
If your household has children or elderly or disabled
residents, consider using a lower temperature setting.
Read all the instructions in this manual carefully before
changing the temperature setting.
Feel the water before using it on children, the elderly, or the
disabled.
If it is necessary to set the water temperature above 125°F
(52°C), consider installing a thermostatically-controlled
mixing valve or temperature-limiting valve. Contact a
licensed plumber or your local plumbing authority for more
information.
