Concealed distributor box P-MAX 1 - 450mm IVAR.P-MAX 1

Product detailed description

This concealed distributor box is designed for embedding in drywall during the installation of underfloor heating or radiant panel systems. It provides a secure and concealed housing for manifolds and associated pipework, ensuring a clean finish and protecting components from damage. The box is commonly used in residential and commercial buildings where hidden installation is required behind plasterboard or similar finishes. Installers typically integrate it during the early stages of construction, prior to surface layer application.

The unit supports manifolds from the IVAR CS 501, CI 553, CS 553, CI 557, and UNIMIX series. The adjustable mounting range allows for adaptation to different wall thicknesses, while the front cover ensures accessibility for inspection and maintenance. The design is intended to remain embedded, with the front panel and doors protruding slightly to allow for operation and servicing.

The technical parameters define the suitability of the box for specific manifolds and installation conditions. The adjustable height and depth ensure compatibility with different wall constructions. The galvanised steel construction provides corrosion resistance, and the white coating on the front cover ensures a neutral appearance for integration into interior finishes.

Installation and connection

Installation requires cutting an opening in the wall surface to accommodate the box’s dimensions. The height and depth can be adjusted within the specified range using the internal mounting brackets. Once positioned, the box is fixed to the wall structure with screws. The front panel and doors are then attached to provide access to the manifold. During installation, it is important to verify that the box is level and properly aligned with the manifold connections. Common mistakes include incorrect adjustment of the mounting brackets or failure to account for the final surface thickness, which can lead to misalignment or difficulty in closing the doors.

Compatibility and accessories

This concealed box is specifically designed for use with the IVAR CS 501, CI 553, CS 553, CI 557, and UNIMIX manifolds. When ordering, ensure that the manifold model is compatible with the box dimensions and mounting requirements. Additional components such as sealing gaskets or mounting hardware may need to be ordered separately, depending on the installation method and surface materials.

Technical background for designers

The box operates as a passive housing for the manifold, providing mechanical protection and a stable mounting platform. The galvanised steel material resists corrosion and ensures long-term durability in dry indoor environments. The adjustable mounting range allows for flexibility in accommodating different wall constructions. The white coating on the front cover ensures a neutral appearance and integrates well with standard interior finishes. The performance of the system depends on correct alignment with the manifold and proper sealing of the box to prevent air or heat loss.

Service and operation

During operation, the front panel and doors should be inspected periodically for signs of wear or damage. Ensure that the doors open and close smoothly and that the sealing remains intact. No regular maintenance is required beyond visual inspection. If the box becomes damaged or difficult to access, it may be necessary to replace it during major system overhauls.

Frequently asked questions

Can the P-MAX 1 box be used with IVAR.CI 557 manifolds?
Yes, the P-MAX 1 box is compatible with IVAR.CI 557 manifolds as listed in the technical specifications.

Is the box suitable for embedding in concrete walls?
It is designed for embedding in drywall or plasterboard. Use in concrete walls would require additional reinforcement and is not recommended.

What is the maximum number of manifolds that can be installed in the box?
The number of manifolds depends on the specific model and dimensions. Refer to the manufacturer’s technical documentation for detailed guidance.

Can the front cover be painted after installation?
The front cover is already finished in white RAL 9003. Painting it after installation is not recommended and may affect the appearance and sealing.
