Temperature Regulation
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 permanently injured by hot water
than others. These include the elderly, children, the infirm, or
physically/mentally handicapped. 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, some type of tempering device, 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 supply or hardware stores. Follow manufacturers
instructions for installation of the valves, Before changing the
factory setting of the thermostat, see Temperature Settings table
at right.
Never allow small children to use a hot water tap, or to draw
their own bath water. Never leave a child or handicapped person
unattended in a bathtub or shower.
