reservoir is equipped with a maximum temperature switch to
ensure your safety. The device will automatically switch off if
excessive heating takes place. When this happens, switch off
the appliance for a few minutes by removing the plug from the
power supply socket and allow the appliance to cool. The ap-
pliance can be reconnected to the mains power supply again
after approximately 20 minutes.
