• 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.
• The unit is heavy. Be careful during transport and installation. Risk of injury through pinching. Use
protective clothing.

Warning
• Make sure that the mains power supply to the unit is disconnected before performing any maintenance
or electrical work!

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.

• Try to restart the fan by cutting the power a couple of minutes.
• Ensure that the impeller is not locked. Disconnect the power supply, remove any obstacles. Check that the fan starts
after reconnecting the current. Should the fan not start please contact your place of purchase.
