The fan should be inspected and cleaned when necessary but at least once a year so that imbalance and excessive
wear on the bearings is avoided. At any sign of wear, contact technical support. A filter before the fan inlet can extend
the fan cleaning interval. At other damages (eg, cable and cable glands), please contact technical support.
If the screws need to be changed then the strength class of new screws must be at least 8.8 and with suitable screw
locking. Required tightening torques M4=1,5 Nm, M5=2 Nm and M6=5 Nm. Cable glands=max. 5 Nm. Nuts in junction
box at EX 140A/180A = 1,2 Nm.
Should fans be on stock or put into operation after a long period, or if they have been exposed to condensation during
an extended period, the motor winding insulation resistance must be measured before the fan is put into operation. If
the values are equal to/less than 1.5 Mohm, the motor winding must be dried. Contact technical support for
instructions.
The fan mainly consist of recycled materials that can be recycled again when the service life of the product has ended.
Check and follow the relevant legislation for recycling.
