• L = Channel length
• T = Wall thickness
• I = Sound insulation
• M = Motor
• K = Core

3 - Use the included template for easy marking of required drill holes for mounting and entry for hidden cabling.

4 – Remove the front cover by lifting the retaining tabs at the top of the front cover.

5 – Place cores and sound-insulating mat in the tube

Place the core and the silencer in the pipe. Roll the silencer so that it matches the pipe diameter. Shorten the silencer so that it matches the wall thickness with the core in the pipe on the outside. The silencer is installed loosely so that it can be removed during maintenance of the unit.

6 – Connect the plug

Connect the control panel connector according to the external device connection diagram. Connect the connectors on the switch and on the control panel to each other.

Mount the inner screen
