MAINTENANCE
6.2 Maintenance
General controls:
• Unusual operation noise?
• Fan capacity for possibly exceeded duct system still sufcient?
Our fans are maintenance free in normal operation!
6.3 Repair
Before any repairs are undertaken please:
- Stop fan in accordance to regulations and disconnect all poles from mains supply.
- Wait until impeller is stationary!
- Make sure that a restart is not possible!
Only use original spare parts manufactured and supplied by Wolter!
Change complete tube fan in the case of defect or faulty operation. (→ “Installation“)
Our fans are maintenance free with normal operation. In case servicing has to be done anyway:
- Bring the fan to a halt in the prescribed manner and completely isolate the fan from the mains supply!
- Wait until the rotor has come to a halt!
- Ensure that the machine cannot be switched on again!
- Clean the fan. Clean the suction apertures. Clean the rotor (if necessary dismantle the protective anti-intrusion
tting)
6.1 Servicing and cleaning
The following safety notes must be observed when maintaining the machine.
- Unexpected reconnection to power suplly could lead to serious harm. The fan has to be assured against
accidental switch-on.
- Risk of injury at sharp-edged parts of fan housing.
- Insecure manual operation leads to a high risk of injury by shearing at the fan impeller. Never reach into the
moving fan! Wear formtting cloth - prevents catching cloth by airow and winding up at the impeller.
