Mixing Valve Usage - Kenmore 153.331350 Use & Care Manual

Mixing Valve Usage
Water temperature over
125°F (52°C) can cause
severe burns instantly
resulting in severe injury or
death.
Children, the elderly and the
disabled and are at highest
risk of scald injury.
Feel water before bathing or
showering.
Temperature limiting devices
such as mixing must be
installed when required by
codes and to ensure safe
temperatures at fixtures.
Water heated to a temperature which satisfies
space heating, clothes washing, dish washing,
and other sanitizing needs can scald and cause
permanent injury upon contact. Short repeated
heating cycles caused by small hot-water uses can
cause a temperature increase of the hot water by
20F ° (11C °) higher than the heater's temperature
settings.

Some people are more likely to be permanently
injured by hot water than others. These include
the elderly, children, the infirm and the physically/
mentally disabled. Table 3 (published by U.S.
Government Memorandum, 1978) shows the
approximate time-to-burn relationship for normal
adult skin. If anyone using hot water provided by
the water heater being installed fits into one of
these groups or if there is a local code or state law
requiring a certain water temperature at the point of
use, then special precautions must be taken.
