7.3.7 Checking the damper
A faulty damper can give rise to disturbances that may result in serious problems. Make sure to check all
three dampers.
• Check operation of the damper actuator.
• Check that the damper tightens when closed. If not, adjust the damper actuator to make the damper
tight (does not apply to trim dampers).
• Check the sealing strips.
• If the damper does not operate, check that nothing is stuck between the drive mechanism and damper
blades to interfere with the damper function.
