Assembly instructions


				The assembly of EN 654 and EN 654.1 fluid level indicators is very easy and economical. It is sufficient to drill two holes of Ø 10.5 or Ø 12.5 mm at distance l₁ in the container wall. The fluid level indicator can also be mounted directly, i.e. without nut, if the container wall is provided with the corresponding thread. All component parts necessary for the assembly are included: hexagon nuts, O-rings, and serrated lock washers for securing. For a perfect sealing by the O-rings, the screws should not be overtightened (max. 12 Nm). Recommended roughness of the sealing surface, Ra = 3 μm.
