Planned Maintenance Programme

Applicable to fresh air intakes, aggressive / hostile / inclement conditions and coastal areas.

Suitable access to dampers, for maintenance and inspection purposes, shall be provided by others.

The Maintenance department responsible for this programme should keep a Log of Date and type of Maintenance carried out.

Dampers should be visually inspected and their operation checked a minimum of once every three months.

Any dirt or foreign matter that may affect the correct operation of the damper should be cleared, from the blades and blade drive area.

Damper inner casing and Blades should be cleaned and sprayed with a light protective lubricant (such as Rocol Z30 *), with special attention being given to the blade end bearings and the damper being worked manually through its full travel to ensure free running of the gear train.

On dampers with External Linkages the blade linkage pivoting points shall be sprayed with
a light oil (*) to aid movement.

Dampers with concealed linkages can be sprayed with a light oil (*) to the drive areas.

Spring Return Motorised Damper blades can be wound and locked open for inspection purposes without the electrical supply by means of a manual crank key that is supplied attached to the actuator. The damper will revert to its initial position when unlocked and allowed to rewind.

Generally no spares are required for the Damper head units. The actuators are maintenance free and should be replaced in the event of failure.
