Add Switch the boiler off. water to the installation if necessary. LTALW7H000215b - Open the valves on all radiators connected to the heating system. Wait until the temperature drops below 40°C and the radiators seem - Set the room thermostat to as low a temperature as possible.
- Page 14 - Open the valve (1/4 turn). - Close the disconnecteur when the manometer indicates a pressure of 2 bar. - Fill the low flow heating circuit using the drainage tap in order to favor the bleed. - When the pump has stopped, bleed again and top up the water pressure.
- Page 15 Bleeding the heating system It is essential that you bleed any air in the calorifier, the conduits or the taps to prevent the annoying noises likely to be produced during heating or when drawing off water. - Bleed the radiators. - Open the valves on all radiators connected to the heating system.
