Manifold/collector assembly - cabinet P-KLASIK 2 - 5/4 "xEK; 4-way; brass IVAR.CS 553 DRS

Product detailed description

This manifold/collector assembly is suitable for installation in central heating systems using radiators. It is commonly used in residential and commercial buildings where precise flow control and system balancing are required. The brass construction ensures durability and corrosion resistance, making it ideal for long-term use in closed heating circuits. The assembly supports both primary and secondary circuit connections, allowing for efficient heat distribution and return flow management.

Typical applications include multi-loop radiator systems, especially in configurations combining radiators with other heating methods. Installers should ensure all components are compatible with existing piping and that the system is properly flushed and treated before commissioning to avoid blockages and reduce wear on internal components.

Technical parameters

The operating temperature limit of +120°C and PN 10 pressure rating are essential for determining system compatibility and safety. These values influence the choice of pipe materials, insulation, and the type of sealing compounds used during installation. CW617N brass provides high strength and resistance to thermal cycling, making it suitable for continuous operation in demanding environments.

Installation and connection

The unit features 5/4"xEK threaded connections for secure and leak-free coupling with standard copper or steel pipes. During installation, ensure the cabinet orientation allows for easy access to valves and fittings. Mounting brackets must be fixed to a stable surface to prevent vibration-induced stress on the manifold body. Check that all valves are in the correct open/closed position before connecting to the system. A common mistake is failing to align the inlet and outlet ports correctly, which can lead to flow imbalances and reduced efficiency.

Compatibility and accessories

This assembly is designed for use with standard radiator circuits and requires compatible piping and insulation. Additional components such as balancing valves, pressure relief devices, and expansion tanks should be selected according to system requirements. The cabinet is available in three variants: wall-mounted (add +N to the code), built-in (code only), or without cabinet (add +BS). Always specify the desired cabinet type when ordering to ensure correct delivery.

Technical background for designers

The manifold operates by dividing the incoming hot water flow into multiple circuits and recombining the return flow for efficient heat exchange. The CW617N brass alloy offers good mechanical properties and resistance to dezincification, ensuring long-term reliability. Proper sizing depends on the total heat load, pipe diameters, and required flow rates. System efficiency is maximized when the manifold is paired with thermostatic valves and a balanced control strategy.

Service and operation

Periodic inspection of valve seals and manifold joints is recommended to detect early signs of wear or leakage. The automatic air vent and drain valves should be checked for clogging and functionality. Before commissioning, the system must be thoroughly flushed and treated with recommended inhibitors to prevent sludge formation and corrosion. No specific service intervals are provided, but regular visual checks are advised during routine maintenance.

Frequently asked questions

Can this manifold be used with underfloor heating in combination with radiators?
Yes, but the system must be flushed and treated with inhibitor solutions before operation to prevent debris from damaging components.

What sealing material is recommended for the threaded connections?
Use high-temperature-resistant sealing tape or compound suitable for CW617N brass and PN 10-rated systems.

Is the cabinet included in the standard delivery?
No, the cabinet type must be specified at the time of ordering. Options include built-in, wall-mounted, or without cabinet.

How are the valves configured in the assembly?
The distribution manifold includes regulating valves, while the collection manifold includes shut-off valves for individual circuit isolation.
