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 DVV/DVVI (I = sound insulated) fans are intended for installation in ventilation systems, outside buildings only (on roofs).
Transport, storage 4 Transport, storage 4.1 Transport Each fan leaves our plant in an electrically and mechanically proper condition. The fans are delivered in wooden crates. We recommend transporting the fans to the installation site in original packaging. 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.
Description 5 Description The fan structure is completely made of metal parts only. The casing is manufactured from seawater resistant aluminium. The base plate with nozzle consists of pre-galvanized steel. Impellers with backward-curved blades are welded and galvanized respectively made of stainless steel (F600). They are fastened together with hub and secured screw directly on to the motor shaft. Dynamically balanced to BV-3, ISO 14694.
Electrical connection 6.2 Preconditions for installation DVV fans must be installed on roofs, outside fire zone (DVV/F for exhausting from fire zone). The fans must be mounted on a flat, horizontal roof base (<10 mm/m) with height of min. 250 mm over the roof top (motor shaft vertical). The base shall be accordingly designed (load capacity, stiffness, insulation), if not proved Systemair accessories used.
Commissioning only certified cable. The electric cable must not be in contact with or be fastened to the casing of the fan (F400, F600 only, high temperature!). Connecting possibility see Appendix 5. Electrical data on the fan nameplate must comply with the provided mains connection. Equivalent motors from different suppliers may have slightly different nominal data than in catalogue. NOTE Motors have serial built-in PTC.
Operation The safety devices have been fitted (protection against contact with rotating impeller). The protective conductor and external earth conductor have been connected. The thermal protection is properly connected to the motor protective device: - the motor protective device is functional; - the thermal protection is functional. The cable glands are tight. Provided mains connection complies with the data on the nameplate. The current (from the nameplate) does not exceed the mains data. 8.
Operation 9.2 Operating conditions During operation, touching the impeller must not be possible. Safety components must not be bypassed or put out of function. 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! The fan may operate only within the limits declared on the nameplate.
Maintenance/troubleshooting WARNING Hazard from electrical voltage and flying parts! Errors occurring can lead to personal and/or property damage! Switch the fan immediately off as planned: In cases of a non-typical noise from bearings, vibrations, pressure pulsation. In case of overcurrent, overvoltage or temperature (nameplate). Then try to find the reason - see chapter 10.
Maintenance/troubleshooting 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. Wrong direction of rotation. Too high pressure drop in system. Obstacles in duct. Short-circuit. Damage to the bearings. Impeller blocked or grinding. Overcurrent Noise Vibrations Damage to the bearings. Impeller blocked or grinding.
Maintenance/troubleshooting VDMA 24186-1 Description Maintenance interval Monthly Fan and electric motor of the fan Check the drainage for function Check to dirt, damage, corrosion and fastening Functional cleaning Check the terminals for tightness Test the fan for function und operational readiness (test run app. 15 min.
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.
