WARNING
Risk of death due to moving parts
Risk of death when closing fins, moving coupling bars or gears due to crushing
between two moving parts.
• Attach separating protective devices (e.g., downstream grid, duct) to the
damper.
• Before opening the door, switch off the AHU and secure it against restarting.
• Do not reach between the fins.
Check screw fittings and connections for tight fit.
Coupled dampers
In case of coupled dampers, check connecting bars for force-locking connection and for correct
function, i.e. direction of rotation and end position of the dampers.
