Dunkirk ARTESIAN 220 Installation And Operating Instructions Manual page 2

Manufacturer's Warning
To reduce the possibility of injury due to scalding, a thermostatic mixing
valve should be installed on all installations. Failure to do so will result
in domestic water being delivered to the faucets at a temperature
equivalent to the boiler water.
All commercial installations requiring sustained water temperatures
beyond 120°F, must label all fixtures alerting water users of a potential
scalding hazard.
