Installation | 7 Installation Safety information Danger: Risk that the fan does not work in case of fire. ♦ Use installation material with fire resistance classes that meet temperature requirements. Warning: Danger from falling fan or fan parts. ♦ Check the surface before installation for load bearing capacity. ♦ Consider all static and dynamic loads when selecting hoisting equipment and fastening components.
14 | Installation Mounting feet Depending on the kind of fan and the construction size, mounting feet are either included in the delivery or available as accessories. If you are not sure, check the online catalogue or contact Systemair. Avoid resonance frequencies Important Risk of damage to the fan due to resonance frequencies ♦ The minimum fan speed should be double the resonance frequency of the anti-vibration system (vibration dampers). ♦ To avoid resonance frequencies, see 8.
Installation | Lifting and positioning The weight of the fan units varies depending on the motor size and accessories. As a result, the fan unit can also be very bulky and heavy. You can find precise information on the name plate or the data sheet. Caution Risk of parts falling down ♦ When fitting the fan, pay attention to its weight and the weight of the components. Lifting Positioning ♦ Lift the fan unit slowly and carefully. ♦ Observe the arrows on the name plate or the housing of the fan.
16 | Installation 7.2.1 Installation of the ventilation system Preconditions ♦ The air flow of the fan must be able to open the air operated damper (LRK). Installation duct 1 ♦ Do not place a duct bend directly before or after the fan! • This can cause damage to the bearings or other parts of the fan. • The duty point may not be reachable. min. 2,5xD • The fan may make noise. ♦ Ensure a direct, smooth and constant air flow to the device. Ensure a free exhaust, see the following pictures.
Installation | 7.2.2 Installation of flexible connections Important Increasing noise emission ♦ Do not install the flexible connections at an angle. Note: When fitting the flexible connections, make sure that they are fitted according to the installation length (Table 9 Flexible connections — Installation length, page 17), without compression or tensile strain. They must not be used to compensate any lack of precision in the assembly. Table 9 Flexible connections — Installation length EV (-25...
18 | Installation 7.2.3 Installation silencer ♦ Ensure correct installation of the silencer. • This can cause damage to the bearings or other parts of the fan. • The duty point may not be reachable. • The fan may make noise. ♦ Ensure a direct, smooth and constant air flow to the device. Ensure a free exhaust, see the following pictures. ♦ To reduce transmission of vibration to the duct system, we recommend flexible connections from our accessory range, see 5.2.3 Accessories, page 7.
Electrical connection | 7.3.1 Deflector For optimal guidance of the air current, a deflector made of galvanized steel sheet can be mounted on the pressureside silencer (accessory). The deflector as accessory for AJR/AJ8 is delivered in a separate package. ♦ Before installing the jet fan, fasten the deflector on the silencer of the pressure side (see arrow). ♦ Position the deflector fins so that after fastening the jet fan to the ceiling, the air flow is directed downwards at a 10° angle.

24 | Troubleshooting/maintenance/repair Note: For all other damage/defects, please contact Systemair. Defective safety-relevant fans (for Ex and smoke extraction applications) must be replaced completely. 11.2 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.
Troubleshooting/maintenance/repair | Activities for fans used for emergency operation. cont'd Operational readiness of the emergency system Allow the "emergency" system to run for 15 minutes X Function of the “emergency” control Test whether the “emergency” control effectively bridges all the other controls and switches X Function of the standstill heating Switch the motor off. The standstill heating must switch on automatically and remain switched on X 11.
26 | Cleaning 11.5 Spare parts ♦ Use original spare parts from Systemair only. ♦ When ordering spare parts, please specify the serial number of the fan. This can be found on the name plate. 12 Cleaning Safety information ♦ Cleaning may only be carried out by adequately qualified persons, details see Table 1 Qualifications, page 2. ♦ Observe the 5 rules of electrical safety, see 2.3 5 rules of electrical safety, page 2!
