The boiler will not function directly. The automatic de-aeration programme
of about 17 minutes will start after one of the three program keys is pressed.
The display will show where A stand s for Automatic de-aeration
programme Active and the number on the right indicates the actual water
temperature of the boiler.
Check the water pressure regularly and top up the installation when necessary.
The working pressure of the installation should be between 1.5 and 1.7 bar
It can take a while before all air has dis-appeared from a filled installation. Especially
in the first week noises can be heard which indicate the presence of air. The
automatic air vent in the boiler will make this air disappear, which means the water
pressure will reduce during this period and therefore topping up with water will be
necessary to adjust the flow water temperature
