General information 1. General information 1.1 List of information DANGER Direct danger Failure to comply with this warning leads directly to death or to serious bodily harm. WARNING Possible danger Failure to comply with this warning potentially leads to death or to serious bodily harm. CAUTION Hazard with a low risk Failure to comply with this warning potentially leads to moderate injuries. ATTENTION Hazard with risk of property damage Failure to comply with this warning leads to property damage.
1.3 Notes on the documentation WARNING Hazard as a result of improper dealing with the fan These operating instructions describe safe use of the fan. Read the operating instructions carefully! Keep the operating instructions with the fan. They must be permanently available at the place of use. 2. Important safety information 2.1 Safety notes Designers, installers and operators are responsible for the proper mounting and intended use. Only use the fan in a proper condition.
Warranty DVV Ex fans are suitable for extraction of clean air, air with a low dust and grease content, media up to max. density of 1,3 kg/m³ and permissible moisture of max. 95 %. The maximum permissible operating data on the name plate apply for an air density ρ = 1,2 kg/m³ (sea level) and a maximum air moisture of 80 %.
Check delivery Check the fan for obvious defects, which can impair safe operation. First of all, pay attention for defects on the connection cable, terminal box and impeller, cracks in the housing, missing rivets, screws or covering caps. 4.

DANGER Explosion-protection! Before and after mounting check manually if the impeller rotates smoothly. Install the fan only, if the minimum air gap between rotor and nozzle matches the value from Appendix 1. The fans shall be fixed to the base with 4 screws in the corners. Avoid distortions of the casing at installation. Ensure unobstructed and uniform intake into the fan as well as free outlet. Install connecting ducts and accessories.
Commissioning WARNING Hazard from electrical voltage! Electrical connection only by a trained electrician rsp. trained and instructed qualified personnel! Electrical connection in accordance with the valid regulations. Prevent the ingress of water into the connection box.
Provided mains connection complies with the data on the name plate. The current (from the name plate) does not exceed the mains data. All conductive added and accessory parts have been earthed. 8.2 Commissioning WARNING Hazard from electrical voltage! Commissioning by trained and instructed qualified personnel only! Switch the ventilator on as planned. WARNING Hazard from bursting parts! When checking the direction of rotation, wear safety goggles.
Maintenance/trouble setting - Prevent sucking of foreign particles , this can destroy the fan. Switching frequency: the fan is intended for S1 continuous operation! the control equipment must not allow any extreme switching! ATTENTION Hazard with risk of additional costs In case of speed control via frequency converter - min. 20 Hz ÷ max. 50 Hz (rsp. 60 Hz, if declared for 60 Hz), it is recommended use of combination of frequency converter and appropriate allpole sine filter (or dU/dt filter).
WARNING Hazard from electrical voltage! Observe at maintenance and service: Impeller must stand still. Electrical circuit must be interrupted and secured against restarting. Observe the rules for safe work. CAUTION Danger from hot surfaces! During maintenance and cleaning wear protective gloves! 10.1 Malfunctions and service The ventilator does not run Check connection to the mains and thermal protection. If ok. check electric motor.
Maintenance/trouble setting The fan is by built-in for-life lubricated ball bearings as far as possible low-maintenance product. After their life time (app. 30.000 to 40.000 h), a replacement of the bearings is necessary. Observe attached instructions of motor manufacturer. Pay attention to a non-typical noise from bearings. For damages (e.g. damage to winding) please contact our Service Department. Repairs may be accomplished only in the company of manufacturer and by the manufacturer.
11. Uninstalling/dismounting WARNING Hazard from electrical voltage! Switching off and uninstalling only by a trained electrician or trained and instructed qualified personnel! Observe 5 safety rules for the electrical expert! - disconnect from the power supply (all-pole), - prevent switching on again, - test absence of voltage, - earthing and short-circuiting, - protect adjacent live parts by covers and barriers and fit a suitable warning notice.
