Initial operating check
The 0400MAN damper should only be commissioned once the installation has been completed.
The damper should be inspected thoroughly to ensure that it is clean and free of any internal debris before
the damper actuation is tested as per the following instructions;
•
Remove the access door.
•
To operate the damper the thermal fuse must be unscrewed, then turn the handle anticlockwise until
it is in the open position, as shown on the label.
•
The damper blade is under tension from a spring so the handle must be held in position whilst the
thermal fuse is re-tightened, the blade will hold in the open position.
•
To ensure the damper is operating correctly the damper should be tested by first checking that there
are no obstructions to the handle and that it is free to move. Then unscrew the thermal fuse quickly,
this will release the blade to its closed position.
•
Check that the blade is in the closed position by checking that the handle is in line with the close
position on the label.
•
If everything is satisfactory then reset the damper to its correct position, either fully open or if it is to
balance air then this can be done so long as the damper remains at least 50% open.
•
Re-fit the access door.
•
If the damper has not closed, the blade may have been incorrectly positioned, or the damper may be
faulty. Please contact Advanced Air for advice.

Maintenance
0400MAN dampers are installed as a life safety product and it is essential that they are always maintained in
good, clean working condition. In accordance with BS9999 Annex W.1 maintenance and inspection should
be undertaken annually.
Maintain the dampers as follows;
•
•
•
•
•
•
•
•
•
The damper is fully open
when the handle is rotated
to the 'Open' position.
Mark the handle position on the label so that it can be reset to the same position after testing.
Remove the access door.
Visually inspect all damper components for signs of corrosion, obstructions and build-up of dirt/dust.
Remove any obstructions, wipe away all dirt/dust from the damper blades and duct surfaces.
After internal inspections are complete a functional check of the damper should be made.
Test the damper by unscrewing the thermal fuse quickly, check that the reaches its closed position.
Reset the damper to its original position and re-tighten the fusible link.
If there is a requirement to change the thermal fuse this can be done simply by unscrewing it fully from
the case and replacing with a new one. The thermal fuse should be replaced if it has been activated,
damaged or part of a regular service plan.
Refit the access door and complete inspection reports as appropriate.
