Installation Steps

1. System Preparation: Isolate and drain the heating system completely.
2. Mounting: Install the filling valve in an accessible location, ensuring the flow direction arrow on the valve body aligns with the system's flow. The valve should be installed horizontally or vertically as per system design.
3. Connections: Connect the inlet (potable water supply) and outlet (heating system) to the respective ports using appropriate fittings. Ensure all connections are watertight.
4. Pressure Gauge Installation: If supplied separately, screw the pressure gauge into its designated port on the valve.
5. Leak Check: Slowly repressurize the system and carefully check all connections for leaks.

Operating Instructions

The Caleffi 574010 filling valve is designed for automatic operation, maintaining the desired pressure in the heating system.

Setting the System Pressure

1. Locate the adjustment knob on the valve (often red or black).
2. Turn the knob clockwise to increase the set pressure and counter-clockwise to decrease it.
3. Monitor the pressure gauge while adjusting until the desired system pressure (typically 1.5-2.0 bar for most domestic heating systems) is reached. The adjustment range is 0.2 to 4 bar.
4. Once set, the valve will automatically open to add water if the system pressure drops below the set value and close when the pressure is restored.
