BSB HD Series Installation Maintenance And Operating Instructions

HD Series Heavy Duty Control Dampers
Installation, Maintenance and Operating Instructions
Models: Flangefit and Spigotfit
Installation:
1. Before installation, the damper should be inspected to ensure that it has not been damaged and is
in good condition following transportation.
2. Ensure that all packing materials are removed, as failure to complete could result in permanent
damage to the product.
3. Ensure that the ductwork and damper flange or spigots are carefully matched, with the specified
sealing material used during installation.
4. Ensure that the ductwork is adequately supported, this is particularly important where large
dampers are concerned.
5. Ensure that the damper is free of any foreign matter, the assembly is not distorted and is square
with no surface damage that could restrict blade movement.
6. If stored before installation, ensure the product is stacked and stored in clean, dry conditions to
prevent the ingress of dust, as well as avoiding excessive temperature or humidity.
7. Care should always be taken when handling dampers on site to avoid subjecting them to
excessive stress for which they are not designed.
8. It is important to ensure that all dampers are installed with airflows and pressures conforming to
the test data as detailed in the manufacturers technical product manual. Excessive airflows and/or
pressures could result in permanent damage and/or malfunction of the damper.
Maintenance:
1. Keep the damper clean and free from any contamination.
2. Where possible, operate the blades against airflow to ensure easy, free movement without
distortion or stress of the linkage.
3. Periodic inspection should be made of any seals that have been fitted to the damper, to ensure
efficient control and operation.
4. It is recommended within normal preventative maintenance procedures for the blades and inner
casings to be cleaned annually, with specific attention being made to ensure all spindles, bushes
and linkage mechanisms are clean and rotate freely.
5. The time period can be ascertained by experience or local regulations, but should not exceed a
twelve month interval. Inspection should be carried out more frequently where excessive dust or
dirty conditions prevail.
6. Normal lubrication should only be made to exposed spindles/bushes and operating linkages
outside of the airflow. Excessive lubrication will attract dust and could fail or impede the
operation of the damper.
