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. Unlock and open the doors with the key included in the scope of delivery (see Fig.43).
2. Remove fan connector (see Fig.44).
3. Remove the fan pressure hoses. Remove the fan slowly and carefully (see Fig.45).
The pressure hoses must subsequently be reinstalled without any risk of confusion!
Pay attention to electrical connections and correct connection of the pressure hoses when installing the fan!
