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, read the
“Temperature Regulation” section in this manual.
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.
