5�5 Service and maintenance of fans
m
Danger to life due to electric shock!
The unit must be fully isolated from the mains power supply before all maintenance and cleaning work.
Risk of injury due to electric shock, moving parts (fan) and hot surfaces�
Cleaning the live unit with water can lead to electric shock.
m
Risk of injury due to high unit weight!
Be careful during service and maintenance work because the fans are very heavy.
The fan must be checked for contamination, damage and corrosion every 6 months:
– Regular inspection with periodic cleaning, if required, is necessary to prevent imbalance due to contamination.
– Clean the fans housing.
– Vibration and oscillation-free operation must be ensured.
– Maintenance intervals depending on degree of impeller contamination!
– Clean the fan with a damp cloth. Do not use aggressive agents that could damage the paint. High-pressure cleaners
and jet water are not permitted.
– If water enters the motor; dry off the motor winding before using it again.
1. Open lock and turn handles counter clockwise to open the doors (Fig.40).
2. Remove fan connector (Fig.41).
