A flow rate meter can be installed instead of the stoppers once all of the hydraulic connections have been made on site. This must be done by the installer
The boxes thus assembled are suitable for connection on the left side of the main pipelines of the centralized system.
Note: for correct built-in installation, the module should be installed with a distance of 135 mm between the back of the box and the wall.
