Hot Water Can Scald!
• Water heated to temperature for clothes washing,
dish washing and other sanitizing needs can scald
and cause permanent injury.
• Children, elderly, and infirm or physically handi-
capped persons are more likely to be permanently
injured by hot water. Never leave them unattended
in bathtub or shower. Never allow small children to
use a hot water tap or draw their own bath.
• If anyone using hot water in the building fits
the above description, or if state laws or local
codes require certain water temperatures at hot
water taps, you must take special precautions:
• Use lowest possible temperature setting.
• Install a thermostatic protective device at
each point of use in addition to the mixing
valve installed at the water heater.
• Water passing out of drain valves may be extremely
hot. To avoid injury:
• Make sure all connections are tight.
• Direct water flow away from any person.
For all applications:
Protection must be taken against excessive
temperature and pressure! — Install a tem-
perature & pressure (T&P) relief valve (like
that provided with the water heater) and ther-
mostatic mixing valve (like that provided with
the water heater). In addition, a thermostatic
protective device at each point of use may
also be necessary.
