First start-up
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!
Checking the heating
■ Turn the rotary selector switch to “III” (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.
Limitation of the water temperature
The temperature of the water leaving the tap for the small wa-
ter heater can be mechanically set to stage “I” (approx. 38 °C)
or stage “e” (approx. 60 °C) (see “Operation”, page 14).
Conserving energy
■ Set the rotary selector to “e” to conserve energy.
■ Hand over the installation and operating instructions to
the user and explain how the appliance operates.
