2.5 First start-up
2.5.1 Electrical connection
• Important: Do not insert the plug into the mains socket yet.
• Fill the appliance with water first. Water must flow from the fitting.
• Only then insert the plug into the mains socket.
Note: If the appliance is not filled with water, the resettable safety
temperature limitation will trip!
2.5.2 Checking the heating
• Turn the rotary selector switch to "3" (approx. 85 °C).
• Monitor the heating process until the pilot lamp switches off after
approx. 12–18 minutes.
• Check the temperature.
CAUTION:
If the safety temperature limitation has switched off the small water
heater, unplug the mains plug, open the warm water tap and allow
approx. 4 litres of water to flow. Then plug the mains plug back in.
The appliance is ready again for operation.
2.5.3 Limitation of the water temperature
The temperature of the water leaving the tap for the small water heater
can be mechanically set to stage "1" (approx. 38 °C) or stage "eco"
(approx. 60 °C) (see "Operation", page 13).
Conserving energy
• Set the rotary selector to "eco" to conserve energy.
• Hand over the installation and operating instructions to the user and
explain how the appliance operates.
