Page 19: Planning Use
Type plate and warnings must always be legible. If it is ascertained during maintenance that they are illegible or missing then they must be cleaned or replaced. Type plate data for the radial fan supplied is given in Appendix A6. Electricity supply A terminal box or maintenance switch can be supplied to connect the fan to the electricity supply as desired. -
Page 20: Installation And Assembly
Storage The fan/s must be stored in closed dry rooms where as even a temperature as possible prevails. This must be above 0 °C and below 40 °C. Avoid direct sunlight, high humidity and dusty, corrosive atmospheres and substances, vibrations and shocks. If stored or turned off for a long time the shafts must be turned once a year to keep them rotatable. -
Page 21: Electrical Connection
Piping connections must be flexible. Suction inlets and pressure outlets may not be mechanically stressed by piping connections. Fans may not be operated when uninstalled. When installing fans make sure the motor ventilation apertures remain unobstructed and that no heated cooling air (e.g. -
Page 22: Commissioning
Commissioning Protective clothing must be worn when commissioning fans. Check the direction the fan rotor turns. This must agree with the directional arrow on the fan housing. Check the motor data on the motor plate. Check that the motor is properly earthed. Check maximum permissible motor RPM. - Page 23 Fault Possible causes Remedial measures Fan runs rough Determine the cause/s of the change/s and Changes in the foundation/s (oscillations and remedy them if possible. and hence major oscillation of vibrations) Check foundation/s and fan and dampen the fan vibrations.
