Manifold/collector assembly - cabinet P-KLASIK 2 - 5/4 "xEK; 6-way; brass IVAR.CS 553 DRS

Product detailed description

Manifold/collector assemblies are essential components in hydronic heating systems, particularly in larger installations with multiple circuits. This 6-way unit is commonly used in multi-zone radiator heating systems where precise flow control and system balancing are required. It is frequently installed in residential, commercial and light industrial buildings with central heating systems that require individual circuit regulation. Installers typically encounter this component during system design, expansion or retrofit projects involving complex heating layouts.

The CW617N brass construction ensures high durability and corrosion resistance, making it suitable for long-term operation in closed heating systems. The inclusion of control and shut-off valves allows for individual circuit management, while the mounting brackets and enclosure simplify installation and system organisation. This unit is designed for integration into systems with standard pipe diameters and requires careful alignment during installation to ensure proper flow distribution.

Technical parameters

Installation and connection

Installation should follow the manufacturer’s guidelines to ensure correct positioning and secure connections. The manifold/collector is connected to the main heating circuit via 5/4"x EK threaded fittings. Each port is equipped with either a control valve or a shut-off valve, depending on its function. The unit must be mounted securely using the provided brackets, ensuring it remains level and aligned with the system layout. Before commissioning, verify that all valves are fully open and that the system is free of debris. Common installation errors include incorrect orientation of the enclosure, misalignment of ports, and failure to check for manufacturing defects such as casting imperfections.

Compatibility and accessories

This unit is compatible with standard radiator and underfloor heating systems using copper or steel pipes. It requires additional components such as balancing valves, insulation materials and pipe supports for complete system integration. Accessories such as isolation valves and expansion tanks may also be needed depending on the system design. Related products include balancing valves and pipe insulation kits, which should be ordered separately based on system requirements.

Technical background for designers

The manifold/collector functions as a central hub for distributing and collecting heated water from individual circuits. The CW617N brass material offers good thermal conductivity and resistance to scaling and corrosion, making it ideal for closed heating systems. The integration of control and shut-off valves allows for individual circuit regulation, improving overall system efficiency. Long-term performance depends on the quality of the system water treatment and regular flushing according to the manufacturer’s instructions. Poor water quality or lack of system maintenance can lead to reduced efficiency and premature component failure.

Service and operation

Regular inspection is recommended to ensure all valves operate smoothly and that there are no leaks or blockages. Check the integrity of the enclosure and mounting brackets periodically. Before commissioning or after system modifications, flush the entire system to remove debris and contaminants. If the system combines underfloor and radiator heating, additional precautions are necessary to prevent sediment accumulation. No specific service intervals are defined in the technical documentation.

Frequently asked questions

Can the manifold/collector be used in mixed heating systems with both radiators and underfloor heating?
Yes, it is suitable for mixed systems provided the system is flushed thoroughly before operation and all components are compatible with the operating parameters.

What type of enclosure is available for this unit?
Three enclosure options are available: a standard cabinet (default), a wall-mounted version (suffix +N) or a version without an enclosure (suffix +BS). Specify the desired option when ordering.

Are the valves included in the assembly interchangeable?
The control and shut-off valves are not interchangeable due to their specific functions. Refer to the manufacturer’s documentation for replacement parts.

Is a system chemical treatment required for this unit?
Yes, the manufacturer recommends using GEL.LONG LIFE 100 to treat the system and prevent internal corrosion and fouling.
