The installer has the obligation to comply with the requirements and procedures for the installation and use of the materials described in this technical documentation, so that the conditions of installation are the same as the samples were tested.
Any deviations from the instructions, affect the validity of the product certification and declaration of correct installation. The damper can be mounted with the axis horizontally or vertically built in the wall/floor or axis horizontally for remote mounting, as in the attached installation manual.
The proper installation and filling is a complex and delicate subject and it isn't sometimes accessible to installers.
Thanks to the partnership with Rf-t, Ecoclima offers a great variety of rectangular and circular european dampers, equipped with DIBt Deutsche Institut für Bautechnik marking. The installation and filling system is based on the WEICHSCHOTT method, which is fast and suitable also for great dimension openings.
The filling system is made of panels with fire resistant coating, acrylic sealant and fire resistant endothermic paint. The panels CFS-CT B protect the opening crossing from the fire. They have a minimum thickness of 100 mm. They're white painted, easy to cut and there is no mineral fiber risks. The dimension of the panel is 100x600x50 mm and the approximate density is 140 Kg/bq. The fire resistant acrylic sealant CFS-S ACR C is used in combination with the fire resistant panels for the filling of small openings, thanks also to the easy application and distribution of the product. The fire resistant paint CFS-S ACR PW is used in combination with the fire resistant panel for the filling of medium or large openings. It's easy to apply and distribute, it's effective also with a single layer of product.
