Change the supply air lter after the alert of the control system.
The alert about lter contamination is active if the working hours of the unit till the lter change notice are set in Flex control panel.
• Fan must be inspected and cleaned at least once a year.
• High-e󰀩ciency bearings are used in the motor. The bearings do not have to be lubricated during the entire operational period of the motor.
• Disconnect the fan from the unit.
• Carefully inspect the fan impeller for accumulated dust and other materials which could a󰀨ect the balance of impeller. The misbalanced impeller
can cause vibration and premature wear of motor bearings.
• Clean the impeller and the interior of casing using mild, non-aggressive and non-corrosive detergent and water.
• For cleaning the impeller do not use high-pressure devices, cleaners, sharp tools or aggressive solvents which could scratch or damage the
impeller.
• When cleaning the impeller, do not immerse the motor in a liquid.
• Ensure that balancing weights of the impeller are in appropriate position.
• Ensure that the casing does not block the impeller.
• Allow the impeller to dry before mounting the fan.
