Preparations for wall installation (with fire protection)

12

Main duct (steel folded spiral-seams duct)

13

Spigot

14

Shaft wall

15

Ceiling compound

16

Floor ceiling

17

Connection duct: Flexible aluminium duct AFR 80

18

Sealing material, e.g. cold-shrink tape

It is essential that requirements in line with approval are observed (Requirements in line with approval).

Damage to unit, malfunctioning in the event of corrosion damage from mortar.

  1. Wrap ventilation ducts, connected to the unit, with a suitable adhesive tape to protect against corrosion inside the brickwork, e.g. using cold-shrink tape.
  1. Correctly attach main ventilation duct inside the shaft.
  2. Apply ceiling compound. To do this, encase the ceiling and pour in the material from above.
  3. Make a wall or shaft opening for the flexible aluminium duct.

  4. Danger to life due to fire transmission in case of faulty ceiling compound.

    1. It is essential that the remaining gap between the main duct and the wall or ceiling is completely sealed with non-flammable materials that are resistant to deformation. For example, use concrete or cement mortar.
  5. Connect the flexible aluminium duct to the main duct and seal for ventilation.
  6. Cut flexible aluminium duct to length, observe a maximum duct length of 2 m.
  7. NOTE! Dimension the length of the flexible aluminium duct so that it protrudes from the wall or shaft so that the connection socket can be attached later. Also attach a ventilation seal on the unit side.
  8. Ensure a suitable, level substructure.
  9. NOTE! Compensate any unevenness in the wall or ceiling so that the housing can be installed without warping. Otherwise it may be that the fan insert can no longer be inserted into the housing or that the degree of protection indicated on the rating plate is no longer guaranteed.
  10. Attach spigot made from shaft material F90 around the shaft.
  11. NOTE! The spigot compensates for the length of the shaft walls in the event of a fire.
  12. Continue with the safety test of the APB shut-off device: Safety instructions for installation of the fire protection shut-off device.
