Installation Services

Frame must be installed on a flat, clean (free of dust and oil) and stable surface Always place the cover inside the frame (locked) before applying the surrounding material The unit needs to be surrounded by a strong stable material (concrete, asphalt, tiles…) If the cover and frame must be water- and gas tight (under pressure), the NBR rubber seal must be installed and the locks closed. If necessary, a thin layer of silicon may be applied to attach the seal to the cover. All locks should then be activated for the seal to be complete.
