Manifold/collector assembly - for underfloor heating - cabinet N-KLASIK 3 - 1 "xEK; 7-way; brass IVAR.CS 553 VP

Product detailed description

This manifold/collector assembly is commonly used in residential and commercial underfloor heating systems. It is installed in mechanical rooms, utility areas, or beneath floor slabs where space allows for the cabinet. The unit is designed for integration with radiant floor heating loops, allowing for individual circuit control and system balancing. Installers typically work with this unit during system commissioning, ensuring correct flow distribution and pressure stability across all circuits.

When combined with radiators or other heating elements, the manifold allows for zoned control of the heating system. It is essential to ensure that the manifold is correctly sized to match the number of circuits and the system's hydraulic requirements. The brass construction ensures durability and resistance to corrosion, making it suitable for long-term operation in heating environments.

Technical parameters

Material	Brass CW617N
Operating temperature	+90 °C
Nominal pressure	PN 10
Code	553975N
Brand	IVAR

The operating temperature of +90°C and nominal pressure of PN 10 define the limits for system design and material selection. These parameters are critical for ensuring the manifold can handle the thermal and hydraulic loads of a typical underfloor heating system. The CW617N brass material is selected for its strength and resistance to thermal expansion, making it suitable for use in systems with high thermal cycling.

Installation and connection

The manifold is connected using 1" external threads (1"xEK) and requires secure mounting with the provided mounting brackets. Installers should verify that all connections are tightened to the manufacturer's torque specifications to prevent leaks. The unit must be installed in a location that allows for easy access to valves and gauges for maintenance and system balancing. A common mistake is failing to align the manifold properly within the cabinet, which can restrict airflow and cause overheating of components. It is also important to ensure that the cabinet type (podium, wall-mounted, or without) is correctly specified at the time of ordering.

Compatibility and accessories

This manifold is compatible with standard underfloor heating systems using polyethylene or PEX piping. It is designed to work with standard heating circulators and thermostatic controls. Accessories such as flow meters, shut-off valves, and pressure gauges are included in the assembly. Additional components such as expansion vessels or balancing valves may be required depending on the system configuration. The unit is not compatible with high-pressure systems exceeding PN 10 or with temperatures above +90°C.

Technical background for designers

The manifold operates by distributing heated water from the boiler or heat pump to individual floor loops and collecting the return flow. The CW617N brass material provides good thermal conductivity and structural stability. The PN 10 rating ensures that the manifold can handle the typical pressure fluctuations in a heating system. Designers should consider the total number of circuits and the required flow rates when selecting the manifold. The inclusion of flow control and shut-off valves allows for individual circuit adjustment and isolation, which is essential for system maintenance and energy efficiency.

Service and operation

Regular maintenance includes checking for leaks, verifying the operation of valves, and ensuring that the system is free from debris. The manufacturer recommends a complete system flush before commissioning, particularly when combining underfloor heating with radiators. This helps prevent clogging and ensures long-term system efficiency. The unit does not require scheduled service intervals beyond these checks. Any malfunction caused by contamination or improper installation is not covered under warranty.

Frequently asked questions

Can this manifold be used in a system with both underfloor heating and radiators?
Yes, but it is important to perform a complete system flush and use a system treatment such as GEL.LONG LIFE 100 to prevent contamination and ensure compatibility.

Is it possible to install this unit without the cabinet?
Yes, the cabinet is optional. When ordering, specify the code alone for a podium cabinet, the code + N for a wall-mounted cabinet, or the code + BS for no cabinet.

What is the maximum operating temperature for this manifold?
The maximum operating temperature is +90°C. Exceeding this temperature may affect the integrity of the system and is not recommended.

Can the manifold be used with a pressure higher than PN 10?
No, the unit is rated for a maximum pressure of PN 10. Using it with higher pressure may cause damage and is not supported by the manufacturer.
