DA/CL 3800 Damper for Flap
2 433372 Mounting Guide
1 Dimmer
Used in areas with a risk of strong gust of wind.
Strong gusts of wind on the leeward side of the building can create a high negative pressure that can close the
inlet flap for a short time. The damper prevents the sound effect that can occur and disturb the animals in these
cases.
Mount the 2 damper hooks on the front of the
frame.
Press the damper so that it clicks onto the back of
the frame.
Press the damper and see if it returns.
Check that the louvers (AFC) can move freely.
