If the pressure dropsbelow 0.7 bar, the built-in pressure sensor blocks the appliance until the pressureexceeds 1.2 bar.• If it is required to top up the system to maintain the minimum recommended waterpressure, always turn the appliance off and only add small amounts of water at a time. If alarge amount of cold water is added in a hot boiler, the boiler can be damaged definitively.• If the system needs to be refilled repeatedly with water, please contact your installer.• Check that there is no water on the floor under the boiler. If there is, please call your installer.• If a condensate neutralisation system is installed, check it and have it cleaned regularly.• Check regularly that there is no error message (lockout) on the screen.
