Description | Unpacking When opening the transport packaging, there is a risk of damage from sharp edges, nails, staples, splinters etc. ♦ Unpack the fan carefully. ♦ Check the fan for obvious transport damage. ♦ Only remove the packaging shortly before assembly. Transport Safety information Warning: Electrical or mechanical hazards due to fire, moisture, short circuit or malfunction. ♦ Never transport the fan by the connecting wire, terminal box, impeller, protection grille, inlet cone or silencer.
| Description Incorrect use Incorrect use refers mainly to using the fan in another way to that described. The following examples are incorrect and hazardous: • Conveying of explosive and combustible media • Operation without duct system or protection grille • Conveying of aggressive media • Operation with the air connections closed • Operation in an explosive atmosphere 5.2 Technical data Max. ambient temperature [°C] Max.

Size 190–225 Size 315–710 A Measuring tubes B Duct system Controller input A - Duct system + Atmosphere A B 8.2 B Assembly/Disassembly impeller — Internal rotor motor If an external rotor motor is used, the motor and impeller can`t be seperated. Damage to the motor and impeller.

14 | Electrical connection 8.3 Assembly tilting device (FTG) Danger of injury by tilting the fan during installation. Leaking duct system. ♦ The tilting device must be secured in the opened state by screws in the designated hole against unintentional folding. ♦ When installing the roof fan and accessories, all mounting surfaces have to be sealed air tight. 1. 2. 3. 6.
Electrical connection | 9.1 Electrical connection accessories The following wiring diagrams show the electrical connections between accessories and fans (with EC motor) or frequency converters (e.g. FRQ, FRQS, FXDM) which can be controlled with a 0–10V signal. If you are not sure if your fan is equipped with an EC- motor please see chapter 6 Name plate and type key, page 9. motor/frequency converter 10V All fans with EC motors are equipped with a pre-wired potentiometer (0–10V).
16 | Commissioning 9.2 Protecting the motor Note: In fans equipped with an EC motor, there is no additional motor protection needed. The motor protection is integrated in the electronics of the motor. Damage to motor due to overcurrent, overload or short circiut. ♦ Lead-out temperature monitors must be integrated in the control circuit in such a way that, if a fault occurs, the motor cannot switch on again automatically after it has cooled down.
Operation | Commissioning of speed-controlled fans Check the fan for vibrations at all normal operation speeds during commissioning. Determine and evaluate vibrations on the housing and bearing areas in accordance with DIN ISO 14694 depending on motor power and positioning. Measurable vibration velocities depend e.g.
18 | Troubleshooting/maintenance/repair Troubleshooting cont'd Air output of fan too low Grinding sounds when starting or operating the fan Thermal contacts/ resistors have triggered Motor does not rotate Electronics/motor overheated Impeller rotates in wrong direction. Change direction of rotation (swap two phases in case of a 3– phase motor). Wrong wiring configuration (e.g. Y instead of Delta). Check and possibly correct the wiring configuration. Pressure losses too high.
Troubleshooting/maintenance/repair | 12.2 Maintenance Warranty claims can only be made if maintenance work is carried out correctly and written evidence thereof is provided. We recommend regular maintenance intervals to ensure continuous fan operation. These maintenance intervals are specified in the “Activities” table below. In addition, the operator must carry out follow-up activities such as cleaning, replacing defective components or other corrective measures.
20 | Cleaning 13 Cleaning Safety information ♦ Observe 2 Important safety information, page 1 Procedure Keeping the fan clean extends its service life. • Install a filter monitor. • Change the filters of the ventilation system. • Do not use steel brushes or sharp-edged objects. • Do not use a high-pressure cleaner (steam jet cleaner) under any circumstances. • Do not bend the fan blades when cleaning.
