Page 11: Mechanical Characteristics Risks
Sign Description Generic hazard warning. Positioned near the condensation discharge plug (if present), to warn of the possible presence of hazardous substances and/or substances at a high temperature. Mechanical characteristics risks The following is a list of specific hazards related to the fan’s mechanical characteristics. WARNING! Risk of personal injury. -
Page 12: Vibration Risks
• Voltage differences due to installation Since it is impossible to establish all-inclusive criteria that can take into account all the possible combinations of these effects, it is advisable to implement a plan of periodical checks according to the effective deterioration noted, so that any variations in structural characteristics can be detected in subsequent checks. -
Page 13: Operating Speed Risks
In the case of fan operation with a variable speed cycle of less than 30 minutes, this cycle must be submitted to approval by the Nederman Technical Office, which will give its approval and notify the consequent reduction of maintenance intervals and the fan life span. -
Page 14: Noise Emission Risks
• The presence of other machines that are also sources of noise emission. Nederman invites the user to measure ambient noise levels. It should be noted that the presence of other operating machines generates a “superimposition of effects” and resonance that multiply ambient noise. -

The rotation direction of a fan is defined for an observer located on the transmission side. 4.2.2 Standard fan outlet position for NCF fans The standard NCF fans are delivered as RD0, shown in Figure 6. Other positions can be delivered on request. Please contact your AB Ph. Nederman & Co representative for assistance. -
Page 20: Installation Types
Type D: intake and outlet connected to a pipe. Clearly AB Ph. Nederman & Co cannot be aware of which of these four installation types will be used by the user. Therefore, the installer or end client themselves must analyze the risks involved for the chosen installation type used in the specific application. -
Page 21: Transport
Lifting and movement operations with the fan may create hazardous situations for exposed persons. It is therefore advisable to follow the instructions provided by Nederman and to use suitable equipment. It is advisable to carry out all lifting and movement operations on the fan and its components with extreme care, avoiding impacts that may affect its correct operation or damage covered parts. -
Page 22: Storage In A Warehouse
4.4.3 Storage in a warehouse CAUTION! Risk of equipment damage. Close intake and exit openings during storage. Should it be necessary to store the fan in a warehouse, it must be protected from atmospheric conditions, humidity, dust and any harmful substances present in the air. It is recommend to periodically check that the fan is in a good condition and turn the impeller manually approximately once a month to prevent the deformation of its bearings. -
Page 23: Electrical Connections
If the available space permits, in installations where the intake is connected to a pipe, we recommend fitting a straight length of pipe with a length approximately 2.5 times the diameter of the impeller, to guarantee correct air flow into the intake. See Figure 8. With installations with an open air intake, we recommend leaving a distance equal to approximately 1.5 times the diameter of the impeller between the fan intake and the nearest wall or machine. -
Page 24: Checks To Be Carried Out With The Fan Running
In the event of overheating of the bearings, contact the Nederman technical assistance department. After 3 - 4 operating hours, with the fan at rest and disconnected from the power supply, check again that all bolts are correctly tightened and the bearing temperature. -
Page 25: Use
WARNING! Risk of personal injury. • When moving, lifting and installing the fan, always follow the instructions provided in this manual. • Never use the fan in conditions other than those indicated by the data on the identification plate. • Never deactivate, remove, modify or in any other way render inoperative safety devices, guards or control devices, either of individual components or of the fan itself. - Page 26 WARNING! Risk of personal injury. • All installation and assembly operations may only be carried out by qualified personnel, equipped with the correct PPE for protection against blows and/or falling objects. • Do not start any maintenance work on the fan (including lubrication) without first disconnecting the fan from the main power supply.
