*WARNING
HOTTER WATER CAN SCALD: Water heaters are intended
to produce hot water. Water heated to a temperature
which will satisfy clothes washing, dish washing, and other
sanitizing needs can scald and permanently injure you
upon contact. Some people are more likely to be perma-
nently injured by hot water than others. These include the
elderly, children, the infirm, or physically/mentally handi-
capped. If anyone using hot water in your home fits into
one of these groups or if there is a local code or state law
requiring a certain temperature water at the hot water tap,
then you must take special precautions. In addition to using
the lowest possible temperature setting that satisfies your
hot water needs, a means, such as a mixing valve, should
be used at the hot water taps used by these people or at the
water heater. Mixing valves are available at plumbing sup-
ply or hardware stores. Follow manufacturers instructions
for installation of the valves, Before changing the factory
setting of the thermostat, read the “Temperature
Regulation” section in this manual.
