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.
1
Open and close all connected draw-off valves at least five
times total. Let water run for at least three minutes, until all
air has been purged from the pipework and the water heater.
Ensure there are no water leaks from any plumbing
connections.
10.3.1 Initial AE3 safety switch activation
Engage the AE3 safety switch by firmly pressing the white
reset button until it clicks and fully locks in place (the water
heater is delivered with the safety switch disengaged).
