The dampers are then locked by turning them slightly clockwise. Balancing On DRU, PSDRU and TDRU the damper blade is stepless adjustable 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. - Page 5 l i n d a b | w e s i m p l i f y c o n s t r u c t i o n Dampers CM 24 / CM 24 F CM 230 / CM 230 F Power supply ......

- Page 11 Assembly In order to fulfil the requirements for air-tightness class D, the devices must be installed as per ‘Assembly Instruction Lindab Safe’. The devices must be installed with the air flow in the direction of the arrow. The devices allow 50 mm duct insulation without the scale or any motor being hidden.
- Page 12 l i n d a b | w e s i m p l i f y c o n s t r u c t i o n Constant/variable flow dampers The flow is adjusted by loosening the central nut and using the knob to turn the scale arrow so that it points to the desired flow on the scale.

- Page 14 Air stream operated dampers CARU, CAR Assembly CARU In order to fulfil the requirements of tightness class D the damper must be installed as per ‘Assembly Instruction Lindab Safe’. The damper is installed by simply placing it inside a duct. Measurement The dampers normally don’t need any maintenance.
- Page 15 In order to fulfil the requirements for air-tightness class D, the bends must be installed as per ‘Assembly Instruction Lindab Safe’. The bends allow 50 mm duct insulation without the measuring points being hidden. For 100 mm insulation, an insulation cup, IK, is available.

Assembly In order to fulfil the requirements for air-tightness class D, the devices must be installed as per ‘Assembly Instruction Lindab Safe’. FMDRU must be installed with the air flow in the direction of the arrow. The devices allow 100 mm duct insulation without sticker or measuring points being hidden. The cup around FMDRU’s damper knob allows 50 mm duct insulation without the knob being hidden. - Page 17 Assembly In order to fulfil the requirements for air-tightness class D, the device must be installed as per ‘Assembly Instruction Lindab Safe’. The device must be installed with the air flow in the direction of the arrow. The device allows 50 mm duct insulation without sticker or measuring points being hidden.
