    A. INSTALLATION A Backdraught Shutter Assembly is supplied. It is packed inside the product during transport. It is designed to block the duct when the fan is off in order to prevent cold draughts from outside entering the building. If you are going to set the fan up to extract air continuously (constant trickle), you do not necessarily need it.
  • Page 5 FLUSH MOUNTING (PANEL/CEILING) A Flush Mount Kit (439256) is required. Remove the Front Assembly by slackening 2 Cover Screws by 2 turns (fig.2). Lift the front assembly away from the bottom edge then the top edge. Mark and cut a rectangular hole 225mm (w) x 255mm (h) through the panel ensuring that there is sufficient space for the product to be installed and that the optional Filter (fig.3) can be removed for maintenance.

  • Page 7 Remove the Cover assembly by slackening the two cover screws (fig.2) by two turns and pull it away.
