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.
Important safety information 1.1.2 List of instructions for action Instruction for action Carry out this action. (if applicable, further action) 1.2 Notes on the documentation WARNING Hazard as a result of improper dealing with the fan These operating instructions describe safe use of the device. Read the operating instructions carefully! The personnel dealing with the fan must read and understand the operating instructions. Keep the operating instructions with the device.
Warranty 2.2.3 Personnel for operation/use, maintenance and cleaning Operation/use, maintenance and cleaning may only be carried out by trained and authorized personnel. The operating personnel must have appropriate knowledge about handling with the fan. In the case of a malfunction or an emergency, they must react correctly and adequately. 2.3 Intended use BKF box fan is intended for installation in ventilation systems. In case of fire it is used to extract smoke gases from the room.
Description WARNING Hazard of impact if the fan falls down! Load and unload the fan carefully in order to avoid possible damage. Pay attention to the weight and dimensions of the packaging. The weight of the fan is visible from the nameplate. CAUTION Danger from cutting edges! Wear protective working gloves when unpacking. Check the fan for obvious defects, which can impair safe operation.
Installation Serially equipped with B5 electric motor 3x400V~, 50Hz, IP 55, insulation class F, with built-in PTC. On request, the fan can be equipped with electric motor intended for other voltage/frequency. Electric motor outside air stream is self cooled. Electric motor Single speed (4 pole, 6 pole, 8 pole) Two speed (4-6, 6-8, 8-12) Two speed (4-8, 6-12) Dahlander 5.1 Connection Y or D Y/Y YY/Y Efficiency class, serially: IE2 or IE3 IE1 IE1 Technical data Size BKF Max. Max.
Electrical connection 6.3 Installation Ensure secure access to the fan for maintenance and service. Installation up to Appendix 2. Fit the contact surface between BKF and flexible connections/duct with temperature resistant sealing tape (not provided with BKF). WARNING Hazard from mechanical distortions! 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 the test protocol.
Commissioning WARNING Hazard from electrical voltage! Electrical connection only by a trained electrician respectively trained and instructed qualified personnel! Electrical connection in accordance with the valid regulations. Prevent the ingress of water into the connection box.
Operation 8.2 Safety elements DANGER Hazard from injurie from rotating parts, if not covered with protective grid! The outlet protective grid is available as accessory. Check if the safety elements e.g. protective grids are fastened. 8.3 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.
Operation WARNING Hazard from electrical voltage and flying parts! Errors occurring can lead to personal and/or property damage! Switch the fan off as planned: In cases of a non-typical noise from bearings, vibrations, pressure pulsation. In case of overcurrent, overvoltage or temperature (nameplate). NOTE At single speed motors with nominal power from incl. 4 kW (D400V) we recommend “star – delta” starting or soft start. 9.
Maintenance/troubleshooting/cleaning 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 all-pole sine filter (or dU/dt filter). It is particularly important, if the supply cable is long, but also to reduce the motor noise.
Maintenance/troubleshooting/cleaning CAUTION Danger from hot surfaces! During maintenance/troubleshooting and cleaning wear protective working gloves to prevent contact with hot motor! CAUTION Danger from cutting edges! Wear protective working gloves when cleaning! 10.1 Malfunctions and troubleshooting (generally) The ventilator does not run Air volume is too low Thermal protection of the fan switches off Possible reasons Connection to the mains fault. Thermal protection triggers. Motor fault.
Maintenance/troubleshooting/cleaning 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 – 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. You will find the address on the back of these operating instructions.
Uninstalling/dismounting 11 Uninstalling/dismounting WARNING Hazard from electrical voltage! Disconnection 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.
