Assembly
In order to fulfil the requirements for air-tightness class C, the damper must be installed as per ‘Assembly Instruction
Rectangular air duct systems’.
For the damper, there is the option of adding a motor later on.
The damper allows a 50 mm duct insulation without the knob being hidden. For 100 mm insulation, an insulation cup,
IK, is available.
Balancing
On LKSR the damper blade is adjusted through 0–90° (0° = fully open, 90° = completely closed) using the knob in the
cup. Locking is performed using screws for Pozidrive (PZD2) and the damper angle can be read off a stamped grade on
the edge of the cup.
Manual damper can be supplemented with a sturdy handle to facilitate adjustment.
Maintenance
The damper and motor normally don't require any maintenance.
