Cleaning the fan
Warning
• Make sure that the mains power supply to the unit is disconnected before performing any maintenance
or electrical work!
• Fan impeller has come to a complete standstill.
Caution
• Beware of sharp edges during maintenance, use protective gloves. Risk of injury through pinching.
The fan should be cleaned when necessary, at least once a year to avoid imbalance and unnecessary damage to the
bearings. The fan bearings are maintenance free and should only be replaced if damaged. Do not use a high-pressure
cleaner (steam jet) when cleaning the fan. Ensure that the fan impeller's balance weights are not moved or the fan im-
peller distorted. Listen for abnormal operating noise.
