Manifold/collector assembly for underfloor heating - cabinet P-KLASIK 2 - 1 "xEK; 3-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 suitable for installations where precise flow control and reliable shut-off are required. The brass construction ensures durability and compatibility with standard heating media. Installers working on mixed systems with underfloor heating and radiators should ensure proper system flushing and maintenance to avoid blockages and inefficiencies.

Typical applications include new builds, renovations, and service upgrades in systems with multiple heating circuits. The assembly is designed for integration into central heating systems with a circulation pump and heat source. The 3-way configuration allows for separate control of supply, return, and bypass circuits, making it suitable for systems with zoning requirements.

The nominal pressure rating of PN 10 indicates the maximum operating pressure the manifold can handle under normal conditions. The maximum temperature of 90°C is suitable for standard underfloor heating systems using water as the heat transfer medium. These parameters are essential for correct sizing and system compatibility, ensuring the manifold can withstand the hydraulic and thermal loads of the installation.Installation and connection The manifold assembly is connected using 1 inch x EK (external thread) connections. Installers should verify that all threads are clean and free of debris before tightening to prevent leaks. The set includes mounting brackets for secure installation in the P-KLASIK 2 cabinet. Common installation errors include incorrect thread sealing, misalignment of the manifold body, and failure to check for system contaminants before commissioning. It is essential to follow the manufacturer’s instructions for system flushing and pressure testing before operation.Compatibility and accessories This manifold is compatible with standard underfloor heating systems using copper or PEX pipes. Additional components such as circulation pumps, expansion vessels, and balancing valves may be required depending on the system configuration. The set includes two ball valves with locknuts, two pass-through unions with automatic air vents, drain valves, and thermometers. No related products are specified for this model.Technical background for designers The manifold operates as a central distribution point for the heating loops, allowing for individual flow control and monitoring. The brass material (CW617N) provides good corrosion resistance and mechanical strength, making it suitable for long-term use in heating systems. The integration into the system depends on the number of loops and the overall system balance. The efficiency and service life are influenced by the quality of the system water, correct balancing, and regular maintenance. The presence of air or particulate matter in the system can reduce performance and cause premature wear.Service and operation Regular checks should include verifying the tightness of all connections, the operation of the air vents, and the accuracy of the flow meters. The system should be flushed periodically according to the manufacturer’s instructions to remove debris and prevent blockages. The use of a system treatment such as GEL.LONG LIFE 100 is recommended to maintain water quality and prolong the life of the manifold. No specific service intervals are provided in the brief.Frequently asked questions
