Result
Cleanliness
Clean where necessary, ensuring damper is free from dust and debris.
Damage and corrosion
Check for any damage or signs of corrosion to damper components.
Drop test
Confirm operation of damper with a drop test by following the below
steps:
●
Relieve the weight of the blade pack from the fusible link with one
hand placed in the centre of the pack width. Ensure bottom blade
remains parallel to top of damper at all times.
●
Failure to support the blade pack from the centre will result in
damper blades falling unevenly, potentially causing damage to
the damper. In event of damage being caused, damper must be
repaired or replaced. Contact HVC for more information.
●
Remove hand quickly, replicating a splitting fusible link, allowing
damper to shut due to springs / gravity.
●
Perform a visual check of the blades, ensure bottom blade has
latched correctly into both lock guides.
Reset
Reset blade pack by pushing (or pulling if a pull ring is fitted) the
bottom blade off the lock guides and pushing blade pack up into the
header. Reset fusible link correctly.
Confirmation
Confirm that damper has been left in normal working condition.
