5.1 Cleaning

To ensure a long service life, check the fans regularly for proper

operation and soiling. The frequency of checking is to be adapted

accordingly depending on the degree of soiling.

DANGER

Risk of injury from rotating fan.

→ Only clean when not in motion. Interrupt the power supply,

secure against renewed switch-on. Secure against start-up,

prevent air flow.

; Dirt deposits on the motor housing can cause overheating of the motor.

; Soiling of the impeller can cause vibration that will shorten the service

life of the fan.

; Severe vibration can destroy the fan.

; In such cases, switch off the fan immediately and clean it.

; The preferred method of cleaning is dry cleaning, e.g. using

compressed air.

; Do not use aggressive cleaning agents!
