XBOXER XBC ECOSMART2 (NT) MODELS
5.2 XBC MOTORISED DAMPERS
Internal version (example code: XBC15-MD-NT).
External weather proof version (example code: XBC15-MD-NT-WP).
If Nuaire matched silencers (example code XBC15-H-MS16) are
being fitted to the fan unit, the motorised damper (example code
XBC15-MD-NT) needs to be fitted after the silencers (as figure 12).
This ensures that breakout noise levels are kept to a minimum.
The motorised damper units will be supplied loose and are designed
to fit directly onto the flange connector (by others).
