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 Instruction for action with fixed order Carry out this action. Carry out this action. (if applicable, further 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.
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 DVG 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 or cardboard boxes. 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.
Description 5 Description 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 (sizes 355 and 450 have impellers made of pre-galvanized steel and tabbed). They are fastened together with hub and secured screw directly on to the motor shaft. Dynamically balanced to ISO 1940 T1, class G6,3.
Installation CAUTION Danger from cutting edges! At installation works wear protective working gloves. 6.2 Preconditions for installation DVG fans must be installed on roofs, outside fire zone (DVG/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 rooftop (motor shaft vertical). The base shall be accordingly designed (load capacity, stiffness, insulation), if not proved Systemair accessories used.
Electrical connection 7 Electrical connection The wiring diagram is placed inside the cover of service switch (also in the test protocol). At DVG-EC the wiring diagram is placed in the connection box. The quality and installation of cables for electrical connection must ensure uninterrupted energy supply, even in case of fire. Inside fire zone use only certified cable. The electric cable must not be in contact with or be fastened to the casing of the fan (F400 only, high temperature!).
Commissioning 7.2 Connection of thermal protection (not applicable at DVG-EC) CAUTION Property damage as a result of motor overheating The motor can overheat and be destroyed if the PTC not been connected. PTC always connect to a motor protective device! 8 Commissioning 8.1 Preconditions Mounting and electrical connection have been correctly performed. Installation residuals and foreign objects have been removed from the fan and ducts. Inlet and outlet are free.
Operation 9 Operation 9.1 Safety notes WARNING Hazard from electrical voltage! The device may only be operated by persons - instructed in function and risks, - who have understood handling and can accordingly react. Ensure access only to persons, who can safe handle the device. 9.2 Operating conditions During operation, touching the impeller must not be possible. Safety components must not be bypassed or put out of function.
Maintenance/troubleshooting NOTE At single speed motors with nominal power from incl. 5,5 kW (D400V) we recommend “star – delta” starting. For this purpose all 7 wires are led to connection box/service switch. NOTE (DVG-EC ONLY) 0-10V speed control input. Modbus controllable. Fire mode to disable motor protection and controller protection in case of fire. 9.3 Operation/use Only use the fan in accordance with this operating instruction and the operating instructions of motor.
Maintenance/troubleshooting CAUTION Danger from hot surfaces! During maintenance/troubleshooting and cleaning wear protective working gloves to prevent contact with hot motor! 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.
Maintenance/troubleshooting Maintenance and check points of fans similarly to VDMA 24186-1 (type, scope and maintenance intervals to be specified in dependence of use and operating conditions). 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.
