When starng the fan for the rst me, the following preliminary checks are necessary:
• Check that all bolts are correctly ghtened (impeller, supports, foundaon bolts, and
transmission components).
• Check that the impeller can turn freely.
• Check that there are not foreign objects inside the fan.
• Check that the fan turns in the correct direcon: power the motor for a brief moment
to see if it turns in correct direcon indicated by the arrow on the fan housing; if
necessary, invert the direcon of rotaon (see Secon
4.5.3. Electrical connecons).
4.7.2 Checks to be carried out with the fan running
Check that the power absorpon does not exceed the value indicated on the motor
idencaon plate, if it does; stop the fan immediately and contact the manufacturer.
The fan must run without excessive vibraon and noise.
Check, with the fan at rest and at an outside air temperature of 20°C, that the bearings do
not exceed the maximum operang temperature (maximum bearing temperature 70°C).
During the rst few hours of operaon, it is normal for the bearings to reach slightly higher
temperatures, as long as they later stabilise at a lower value. In the event of overheang of
the bearings, contact the Nederman technical assistance department.
Aer 3 - 4 operang hours, with the fan at rest and disconnected from the power supply,
check again that all bolts are correctly ghtened and the bearing temperature.
4.7.3 Visual checks on guards
CAUTION! Risk of equipment damage.
• All guards must be inspected every month and replaced if necessary.
• In case of doubts, carry out checks more frequently or replace the guard.
For mesh guards, checks must be made for the following:
• Corrosion or dullness of galvanized surfaces
• Detachment of rivets/welds
• Evidence of noises typical of loose guards
• Impacts and permanent deformaon of components
• Breakage of wires
• Corrosion of fasteners
• Slackening of xing elements
For guards in pressed and painted sheet metal, checks must be made for the following:
• Corrosion or dullness of painted surfaces
• Detachment of rivets/welds
• Evidence of noises typical of loose guards
• Impacts and permanent deformaon of components
• Mechanical deformaon or breakage of guards
• Presence of cracks
• Corrosion of fasteners
• Slackening of xing elements
