General safety instructions

DANGER: Burns
Water temperatures over 125 °F (52 °C) can cause severe
burns instantly or death from scalding. A hot water scald-
ing potential exists if the thermostat on the water heater
is set too high. Households with small children, disabled
or elderly persons may require that the thermostat be set
at 113 °F (45 °C) or lower to prevent possible injury from
hot water.
CAUTION: Burns
If operating with preheated water, e.g. from a solar ther-
mal system, the DHW temperature may vary from the
selected set temperature.
