CAUTION Burns
If the water supplied to the appliance is preheated, the
internal anti-scalding protection limit may be exceeded.
In such cases, limit the temperature with an upstream
central thermostatic valve.
10.3 Initial start-up
Note
During initial start-up, you MUST engage the AE3 safe-
ty switch by depressing the white reset button before
supplying power to the water heater. The unit will NOT
operate until the safety switch has been engaged.
