Safety instructions for the installation of the plastic shutter

Preparing the shaft and suspended ceiling

  1. Make an opening in the suspended ceiling.
  2. Make an opening in the shaft for DN 75 or DN 80 connection duct.
  3. Correctly attach main ventilation duct inside the shaft.
  4. For fire protection systems, use ceiling compound. To do this, encase the ceiling and pour in the material from above.
  5. Fit duct attachments to the ceiling (Preparations for the ER-APB ceiling installation (with fire protection)). Only use permitted mounting material.

  6. Risk of incorrect installation if non-permitted mounting material is used.

    1. Only secure connection duct to ceiling with permitted mounting material (duct clamp or clamping band).
  7. Connect permitted connection duct to main duct and seal for ventilation, for example with cold-shrink tape.
  8. Apply wall/board compound. Seal gap between brickwork and folded spiral-seams duct. The gap remaining must be fully sealed with non-flammable materials that are resistant to deformation. For example, use concrete or cement mortar or for wall boards, use fire protection filler.
  9. Fit suspended ceiling. Ensure a suitable, flat surface so that the fan insert can be safely inserted in the housing later on.
