Installation

Risks of leakages if unit is not sealed tightly enough.

Firmly screw fan down to the duct system at all flange holes. Fit suitable insulation, sound-absorbing and installation materials.

  1. Cut the folded spiral-seams duct at the installation site if the duct system is already installed.
  2. Secure appropriate FU mounting foot to fan housing with suitable screws provided. Any installation position can be selected. Make sure that there is free access to terminal box at the installation site.
  3. Transport the fan to installation site and set it down there. Observe chapter Transport.
  4. Mount pre-assembled fan unit (incl. mounting foot) on the wall, ceiling or bracket. Mounting material of the sufficient size should be provided by the customer.
  5. Lay suitable folded spiral-seams ducts flush against the fan on the inlet and outlet sides. Observe spacing for flexible cuffs or EL or ELA flexible couplings.
  6. Securely screw folded spiral-seams ducts to the fan flange holes with flexible cuffs or with EL or ELA couplings. Screw all flange holes. Ensure seal integrity.
  7. With a free inlet, also fit an SG protective grille as protection against accidental contact and drawing in.
  8. Fit suitable insulation and sound-deadening material.
