Manifold assembly - without cabinet, 1" x EC, 5-way

Product detailed description

This manifold assembly is commonly used in residential and commercial heating systems for distributing hot water to multiple radiators or sanitary circuits. It is suitable for installations where a central distribution point is required for parallel heating circuits. The unit is designed for use in systems with a maximum operating temperature of +120 °C and a nominal pressure of PN 10. It is typically installed in mechanical rooms or utility areas where space allows for proper access and maintenance.

The assembly is ideal for systems with a recommended temperature differential of +75 °C / +65 °C for radiator circuits. It is intended for use without a circulation pump, as the boiler provides the necessary flow. The unit is not suitable for underfloor heating systems unless specific precautions are taken, such as using a separate circuit with thermal isolation from the radiator return line.

The 50 mm spacing between outlets allows for standard mounting on standard wall or floor supports. The 3/4 inch EC thread type is commonly used in European heating systems for connecting to radiators or other terminal units. The PN 10 pressure rating ensures compatibility with standard low-pressure heating systems. The maximum operating temperature of +120 °C is suitable for most radiator heating applications.

Installation and connection

The manifold should be installed in a location that allows for easy access to the ball valves and connections. The 1 inch female inlet should be connected to the main supply pipe using a compatible fitting. Each of the 3/4 inch EC outlets should be connected to individual radiators or circuits using standard EC fittings. It is important to ensure that all connections are tightened to the manufacturer's torque specifications to prevent leaks. A common mistake during installation is not aligning the outlets correctly with the radiators or not providing sufficient clearance for maintenance. The mounting brackets should be securely fastened to a stable surface to prevent vibration and movement. Before commissioning, the system should be flushed thoroughly to remove any debris that could cause blockages or damage to the valves.

Compatibility and accessories

This manifold is compatible with standard radiator heating systems using 3/4 inch EC connections. It is typically used with standard radiators, but can also be used in combination with sanitary circuits if the system is designed accordingly. Additional components such as circulation pumps, expansion vessels and pressure relief valves may be required depending on the system configuration. The assembly includes mounting brackets, ball valves and plugs, but additional fittings and valves may be required for specific applications. It is recommended to use compatible fittings and valves from the same manufacturer to ensure long-term reliability and performance.

Technical background for designers

The manifold operates by distributing hot water from a single inlet to multiple outlets, allowing for balanced flow to each radiator or circuit. The nickel-plated brass CW617N material provides good corrosion resistance and mechanical strength, making it suitable for long-term use in heating systems. The ball valves allow for individual control of each circuit, which is important for balancing the system and adjusting flow rates. The design of the manifold ensures that the flow is evenly distributed to each outlet, reducing the risk of uneven heating. The absence of a built-in circulation pump means that the system relies on the boiler for flow, which is suitable for most radiator heating systems. However, in larger systems or those with multiple zones, a separate circulation pump may be required to ensure proper flow distribution.

Service and operation

Regular inspection of the ball valves and connections is recommended to ensure that there are no leaks or blockages. The system should be flushed periodically to remove any debris that could affect performance. It is important to ensure that the system is properly balanced to prevent overheating or underheating in individual circuits. If the system is used in combination with underfloor heating, it is important to ensure that the circuits are properly isolated to prevent thermal interference. The manufacturer recommends using a system preparation such as GEL.POLY A.P. to protect against corrosion and scale buildup. Any issues with the manifold should be addressed by a qualified technician to ensure that the system continues to operate efficiently.

Frequently asked questions
