- Page 7 &/>>/E' d, ^z^d D WARNING Disconnect the boiler from the mains power supply using the two-pole switch. IMPORTANT: Regularly check that the pressure displayed on the pressure gauge is 0.7 - 1.5 bar, with the boiler cold. In case of overpressure, open the boiler drain tap. In case of insufficient temperature, open the boiler filling tap (figure 3). Open the tap very slowly in order to vent the air.
- Page 8 WZK>KE' ^,hdKtE &ZK^d WZKd d/KE Do not drain the whole system as filling up with water again causes unnecessary and harmful scale to build up inside the boiler and the heating elements. If the boiler is not used during winter and is therefore exposed to the danger of frost, add some specific anti-freeze to the water in the system (e.g.: propylene glycol coupled with corrosion and scale inhibitors).

To solve this problems, two slots closed with pre-punched holes (Ref. A and B) have been prepared on the fumes outlet. These can be easily removed by the Qualified Technical Assistance Service without having to remove the outlet.
