Operation:

Ensure that the blades open and close properly while running the damper through its full cycle. Check

for slack linkage, especially at the actuator, if there is a problem. Tighten the linkage as required.

Closure:

Remove any unnecessary objects that could hinder blade closure or appropriate blade-to-blade or

blade-to-frame seal.

Moving Parts:

Monitor those elements that are supposed to move freely, such as linkages, bearings, and blades, can.

Lubricating these components helps to keep them from rusting and accumulating unnecessary friction

over time. Only use Moli-spray oil or a related graphite-based dry lubricant since regular lubricating oil

attracts dirt more easily. When using ball bearings (without grease fittings) and synthetic, oil-

impregnated bearings lubrication is not necessary.

Foreign Matter:

Dirt and dirt can build up over time on damper surfaces. Wipe the damper surfaces with a non-oil-based

mild solvent/cleaner to avoid impeding airflow and buildup of debris.
