WHAT TO CHECK ON A REGULAR BASIS
Essential recommendations for the correct
operation of the appliance
• Check regularly that the system water
pressure is at least 1 bar when cold. If the
pressure drops below 0.5 bar, the built-in
pressure sensor blocks the appliance until
the pressure exceeds 0.8 bar.
• If it is required to top up the system to maintain
the minimum recommended water pressure,
always turn the appliance off and only add
small amounts of water at a time. If a large
amount of cold water is added in a hot boiler,
the appliance can be damaged definitively.
• If the system needs to be refilled repeatedly
with water, or if there is water on the floor
under the boiler, contact your service
engineer.
