¶ COMMISSIONING TASKS
¶ TASKS DURING FIRST START-UP
The following in particular is checked during the first start-up:
Damper chamber and end walls:
• Correct direction of damper rotation, or switching the actuator switch, see Section 5.28 ACTUATOR INSTALLATION
¶ OPERATION AND MAINTENANCE
Detailed operating instructions and maintenance and service procedures are provided in the following sections and in the sections for the individual parts of the unit.
The blades of an open damper must be secured against self-actuating or accidental closing. Never insert limbs between the blades of an open damper; there is a risk of serious injury!
Check for contamination, any damage, mobility of the damper blades and, in particular, correct closure of the damper. Remove any dust deposits with a vacuum cleaner; the surface of the damper blades may then be cleaned with a damp cloth. The plastic gear wheels of the dampers are made of a material that does not require additional lubrication. For dampers with linkage, lubricate the necessary points of the lever transmission with lubricating spray. If a flexible connector is installed downstream of the damper, check its tightness and integrity and clean it if necessary.
