The fan ingress Protection (IP) rating from solid objects and liquids IPX4 demands
extra protection against water ingress.
To protect the fan against water ingress mount a hood at the intake pipe or under the
roof.
Take steps to prevent ingress of smoke, carbon monoxide and other combustion
products into the room through open chimney flues or other fireprotection devices.
Mounting and maintenance of the fan are allowed only by duly qualified electricians in
compliance with valid rated norms.
Disconnect the fan from power mains prior to any servicing and repair works.
Before connecting the fan to power mains check the fan for any visible damages
of impeller and casing. The casing internals must be free of any foreign objects which
can damage the impeller blade.
Do not use the fan in explosive or firehazardous environment.

Disconnect the fan from power mains prior to all maintenance operations.
Maintenance of the fans means periodic cleaning of the fan surfaces from dirt and
dust when the fan is switched off.
Use a soft cloth or compressed air to remove dust (fig. 13).
The impeller blades require thorough cleaning every 6 months.
The filter prevents the fan soiling and reduces the cleaning periodicity.
To clean the impeller blades follow the further procedure:
Clean the impeller blades with a cloth wetted in water and mild detergent solution.
Avoid liquid dripping on the motor! (fig. 14, 15).
After cleaning of the impeller reinstall the cover and tighten the screws.
Any servicing operations by a professional only!
