Manifold/collector assembly - for underfloor heating - cabinet N-KLASIK 4 - 1 "xEK; 10-way; brass IVAR.CS 553 VP

Product detailed description

Underfloor heating systems in residential and commercial buildings require precise flow control and efficient distribution of heated water. This manifold assembly is commonly used in radiant floor heating applications where multiple circuits need to be managed. Installers working on new builds or renovations will find this unit suitable for integrating with hydronic heating systems. The brass construction ensures durability and compatibility with standard heating media.

When installed correctly, this manifold ensures even heat distribution across all circuits. It is typically used in conjunction with a boiler or heat pump system, and the included valves allow for individual circuit regulation. The unit is designed for wall or cabinet mounting, depending on the installation requirements.

Technical parameters

Material	Brass CW617N
Operating temperature	+90 °C
Nominal pressure	PN 10
Code	553978N
Brand	IVAR

The operating temperature of +90°C and nominal pressure of PN 10 are key factors in determining the suitability of this manifold for a specific system. These parameters ensure compatibility with standard heating systems and allow for safe operation under normal conditions. The brass material (CW617N) is selected for its resistance to corrosion and thermal stress, making it ideal for long-term use in heating applications.

Installation and connection

The manifold assembly is connected using 1 inch external thread (1"xEK) and requires secure mounting to a suitable cabinet or wall. The installation process involves connecting the distributor and collector to the heating circuits, ensuring all valves are properly aligned and sealed. It is essential to check the tightness of all connections and verify that the flow control and shut-off valves are functioning correctly before commissioning the system. A common mistake during installation is improper alignment of the manifold with the heating circuits, which can lead to uneven heat distribution.

Compatibility and accessories

This manifold is compatible with standard underfloor heating systems that operate within the specified temperature and pressure limits. Additional components such as circulation pumps, expansion vessels, and temperature controls may be required depending on the system configuration. Installers should ensure that all components are sized correctly to match the flow requirements of the manifold. No related products are listed for this model.

Technical background for designers

The manifold functions as a central distribution and collection point for the heating circuits. The brass CW617N material is chosen for its high thermal conductivity and resistance to scaling and corrosion. The flow control valves on the distributor allow for individual circuit adjustment, while the shut-off valves on the collector provide isolation for maintenance or system balancing. The integration of this unit into the overall system depends on the number of circuits and the required flow rates. Proper insulation of the manifold and associated pipework is essential to maintain efficiency and prevent heat loss.

Service and operation

Regular maintenance is not required for this manifold, but it is important to check for leaks and ensure that all valves are operating smoothly. Before commissioning the system, a thorough flushing of the entire heating system is recommended to remove any debris or contaminants that could affect performance. If the system is combined with radiators or other heating elements, additional flushing may be necessary. The manufacturer recommends using a system treatment such as GEL.LONG LIFE 100 to extend the service life of the components.

Frequently asked questions

Can this manifold be used with a combination of underfloor heating and radiators?
Yes, the manifold can be used in systems that include both underfloor heating and radiators. However, it is important to ensure that the system is properly balanced and that all components are compatible with the operating conditions.

Is it necessary to install the manifold in a cabinet?
The manifold can be installed in a cabinet (N-KLASIK 4) or mounted on a wall. The choice depends on the available space and the installation requirements. The cabinet provides protection and a neat finish.

Can the flow control valves be adjusted after installation?
Yes, the flow control valves on the distributor can be adjusted to regulate the flow in each circuit. This allows for fine-tuning of the system to ensure even heat distribution.

What should be done if the system shows signs of contamination?
If contamination is suspected, the system should be flushed according to the manufacturer's instructions. The use of a system treatment such as GEL.LONG LIFE 100 is recommended to prevent future issues.
