SAFETY CONTROLS
The heater has a combination thermostat and hi-limit control that is located
above the top-heating element.
This surface mounted hi-limit is designed to interrupt the flow of
electricity to all elements when it senses temperatures of approximately
170°F or greater. If this switch operates, do not attempt to reset. A
dangerous situation is indicated and a qualified service man should be called
to find the source before the unit is operated again
.
Temperature of the water should be tested periodically at the faucet to be sure
thermostats are working properly.
