The fans are designed for continuous use. The fan
should be disassembled and cleaned of dirt at least
once a year, and the engine should be inspected.
The motor should be periodically inspected,
depending on the conditions in which it operates,
but no less than once every 12 months. The
inspection includes a cleaning and visual inspection
of the motor, drive, and protection mechanisms.
The inspection should be performed by a person
entitled to do so with the appropriate
qualifications.
1. Before electrical installation, you should adhere to the proper regulations.
2. Electrical installation should be done by a qualified electrician.
3. Before maintenance or adjustments, you should disconnect the fan from the mains.
4. The electrical installation must include a plug, in which the distance between all the prongs is no less than 3 mm.
5. The appropriate measures should be taken to prevent the reverse flow of gases into the room from a flue or other
appliances with open flames.
6. All maintenance should be done after disconnecting the fan from the mains, even if the fan is not on.
7. The manufacturer reserves the right to make design changes resulting from technological advances.
