Note the direction of air flow (fig. 1). The non-return damper must be removable, accessible for service and maintenance. The axis of rotation of the check damper must always be horizontal. Rotation of the axis will prevent proper operation (fig. 2). Place the check damper perpendicular to the duct, max. 0°- 5° against the direction of air flow (fig. 3). For servicing, we recommend that the damper is installed in the RD service part - instabox.
