4 Maintenance schedule
The following applies for any maintenance works on the fan:
•
The fan must be at zero potential.
•
The electric circuit must be disconnected secured against reconnection.
•
All moving parts must have stopped completely.
•
All safety and working instructions in accordance with EN 50110-1 and EN 1010-1
must be observed.
•
All works must be carried out by qualified personnel in accordance with EN 50110-
1 and EN 1010-1.
Regular maintenance:
•
Regular maintenance extends the service life of the fan and prevents failures.
•
Run the fan once a month for at least two hours at full speed to evaporate any
humidity inside and to avoid corrosion of the bearings.
•
Carry out the following tasks (general cleaning, checking the bearing, the V-belt
and the shutter) every six months.
•
Reduce the maintenance interval to three months if the fan is used to circulate
extremely polluted air. This is the case when poultry is managed in aviaries, when
the fan is used in connection with manure drying tunnels, during moult, etc. In case
of doubt, check the dust layer on the motor. It should not be thicker than 1-2 mm
anywhere.
Caution!
Never carry out maintenance works on running / rotating fans! Always
disconnect the fan from the mains power supply before carrying out
maintenance works.
