Filling the Water Heater
• Check if the rotary switch for the drain
valve is set to ‘Operation’, meaning that it
is parallel to the water connection and
engaged.
•Close the drain valve by pushing the
push button until it engages.
• Switch on power for water pump .
• Open hot water taps in kitchen and
bathroom. Leave the fittings open for as
long as it takes for the boiler to displace
the air and fill up, and the water to flow
without interruption.
