DANGER
HOT
BURN
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.
Do not leave children, the elderly, or disabled persons
unsupervised.
Do not allow small children to play unsupervised in the
bathroom.
Do not allow anyone to change the water temperature while
hot water is running.
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.

temperatures at or above 125°F (52°C) can cause instant
scalding, severe burns, or death. Before you decide to change
