Installation

Installation must be carried out professionally in accordance with the applicable regulations for ventilation channels.

  1. Switch off mains fuse, secure against being accidentally switched back on and position a visible warning sign.
  2. Remove the terminal compartment cover [3] (2 screws).
  3. Install the duct, cut the duct if there is already a folded spiral-seams duct.
  4. Insert the electric air heater between the ducts. Observe the installation position (air direction arrow). Ensure that the folded spiral-seams ducts are pushed over the sealing lips as far as they will go onto the connection socket.
  5. Fit suitable insulation, sound-absorbing and installation materials.
