WARNING! Setting the temperature selector to higher settings provides hotter water
which increases the risk of scald injury. Households with small children or invalids may require a
125°F or lower temperature setting to reduce the risk of scald injury. Allow a few days of operation
at your selected setting to determine the correct temperature setting consistent with your needs.
