G. SCALDING
This heater can deliver scalding water. Be careful whenever using hot water to avoid
scalding injury. Certain appliances, such as dishwashers and automatic clothes washers
may require increased water temperature. By setting the thermostat on this heater to
obtain the increased water temperature required by these appliances, you may create
the potential for scald injury.
To protect against injury, you should install a mixing valve in the water system. This
valve will reduce point of discharge temperature by mixing cold and hot water in branch
supply lines. Such valves are available from your local plumbing supplier.
Table 3 details the relationship of water temperature and time with regard to scald injury and may be used as a guide in determining the
safest water temperature for your applications.
A temperature limiting or mixing valve is recommended in installations servicing disabled or elderly persons, or children. Take extreme
caution to avoid scalding when temperature limiting or mixing valves are not used.
