formance data, max. temperature, work-ing period, category/class according to relevant standards and regulations.A motor plate with relevant data is on the side of the fan casing.Documentation and instructions from the motor manufacturer are included with the fan. Save them for when the fan is serviced.

3.2 Weights

3.3 TransportThe jet fans are delivered on pallets to al-low for forklift handling. Avoid making deformations of the fan casings.

4. StorageThe jet fans are unsuited for outdoor storage.If the fans are stored indoors under well-ventilated conditions with no risk of con-densation, the storage period is 6 months.The storage space must not be exposed to vibrations likely to damage the motor bearings. If the storage period exceeds 3 months, it is recommended to turn the rotor regularly.Check the fans for damages and corro-sion prior to installation. Before start of operation, make sure there is no conden-sate in the motor.

5. Installation

5.1 Before installationMake sure that the rotor rotates freely with equal distance between blade tips and fan casing throughout the circum-ference.

AUO/ARO: Remove the transport brackets on the underside of the fan housing after installation. The brackets have yellow labels. Insert the screws from the brackets again, as these secure the casing.

5.2 InstallationInstall the jet fans so that there is at least 0.5 m to the nearest obstruction on the in-let side and at least 2 m on the outlet side for unidirectional fans. For reversible fans there must be 2 m on either side of the fans.

Lower the fan correspondingly for ob-structions higher than the installation height (H).

Fasten the fan in each of the suspension points to the ceiling or the lowering brackets. It is recommended to install vi-bration dampers as shown in figure 3b or 3c. Please note that these are optional and not part of standard deliveries.Arrows on the fans indicate the airflow direction and rotation.Within a smoke reservoir the jet fans must be fastened to non-flammable ma-terials only and must meet current na-tional requirements. In general, the jet fans must be mounted so that there is no risk of them falling down in case of fire.If unapproved expansion bolts for high temperature are used, these must be made from steel, must at least be size M8 and must be mounted twice as deep as recommended – at least 60 mm deep. The static load must not exceed a pull of more than 500 N.Expansion bolts certified for fire condi-tions must be mounted and loaded ac-cording to the approval.

The jet fans must be fixed to a horizontal plane with a natural frequency at least 20% from the fan speed.After final installation, check that the rotors rotate freely in the fan casings.It is essential for the performance and sound level that the airflow is unimped-ed and free from eddies.

5.3 WiringThe power supply cable must be fitted according to national regulations and meet the EMC regulation.The connection must be done by author-ised personnel. The motor is connected through a thermal relay based on motor nominal current. The connection is ef-fected directly in the switch mounted in the terminal box. Please note AUT, ART and AZT have external terminal boxes.Check if current legislation prescribes in-stallation of f.x. an emergency stop.See figures 4a, 4b, 4c and 4d for connec-tions. Refer also to the motor nameplate and the order specification.

5.3.1 Access to terminals or terminal box (AUO and ARO)

• Remove screw in handle, item 1• Remove handle, item 2• Unscrew screws in cover, item 3• Remove cover, item 4.

Note: The switch can be used as safety isolator.

5.4 Before service

5.4.1 Locking of switch on AUO and ARO

It is recommended to lock the switch in the Off position during maintenance. Use a padlock to prevent turning of the handle.

The switch can be locked in the On or Off positions by removing the little plastic stick opposite the locking position.To remove the stick; dismount the han-dle, cut the stick off with a cutter and re-

mount the handle.

5.4.2 Switching off power supplyThe power supply for the units must be switched off centrally. The control switches must be disconnected and se-cured, before servicing the units.

5.5 Approval for operationThe installation must be approved with regard to operation and interaction. The person responsible for the operation of the system must initiate this test.The approval test must be confirmed. The person responsible for the operation of the system must keep the approval test documents. For jet fans approved for smoke control, the documents must be presented upon request from authori-ties.Check that the fans are clean and free from tools, before start of operation. The rotors must rotate freely. Make sure the electric connections meet the national re-quirements, and that the wire guards on the suction sides and guide vanes on the pressure sides are correctly mounted.To check direction of airflow and direc-tion of rotation, briefly switch the fans on then off. Refer to the arrow plates on the fan casings.In the first 30 minutes of operation, the motors may use more power than stated on the motor plate. This is the running-in period. The amperage depends among other things on the temperature.

5.6 Start-up procedure• Start the fan.• Check for abnormal noise.• After 30 minutes of operation check

that the fans operate normally.

6. MaintenanceThe jet fans must be kept in good and op-erational condition.Observe the following to ensure func-tionality and working life.

6.1 Maintenance

6.1.1 CO-fansFans for CO-ventilation require a yearly inspection and test of functionality. It is recommended to implement procedures in accordance with this requirement.

6.1.2 Smoke fansFans approved for high temperature and smoke ventilation as well as for ventila-tion on a daily basis, must be inspected every six months.Unused fans intended for smoke ventila-tion must be inspected four times a year.It is important that the motor mainte-nance instructions are followed.

6.2 Precautions before mainte-nance

Disconnect the fans from the electrical system before inspection and ensure the fans cannot be started inadvertently. See section “5.4 Before service” for what pre-cautions to make.Fan units with external safety switches must be disconnected at the switches

and secured – f.x. with locks. This can be done in the fuse box or another centrally placed switch.Please note that fans controlled by auto-mation may start suddenly, unless they are disconnected.

6.3 CleaningClean fans and silencers when needed by means of pressurised air or vacuum cleaning.

6.4 VibrationsFrom the factory, the fans are balanced to run without vibrations.Vibrations occurring during operation are normally an indication of accumula-tion of dust and dirt or foreign bodies on the rotor system. If ordinary cleaning does not solve the problem, the fans must stay off-line and expert assistance should be called in. Prolonged operation can damage motor bearings and rotors.

Important: The fan is designed for continuous operation. The following kinds of operation may cause fatigue break in the impeller and endanger people.

- Operation with repeated starting and stopping.

- Uneven flow velocity through fan.

If in doubt, Novenco should be contacted to assess fan suitability.

Important: Do not use high-pressure water for cleaning the fans or silencers.
