Safety Precautions

The information contained in the following pages has been prepared to ensure your
maximum enjoyment of your fan
Please remove the fuse or turn off the circuit breaker to cut off the power before installing
the fan. Ensure all electrical connections are in compliance with local laws, regulations
and national eletrical codes. If you are not familiar with electrical installation and wiring,
please hire a qualified electrician or consult the wiring manual.
1. For your safety, all electrical connections and disconnections should be performed by a
qualified electrician.
2. Any action performed for the electrical connection of the device must be carried out after
ensuring that the general power supply is disconnected,by removing the corresponding fuse or
disarming the protective switch in order to ensure total isolation of the power supply.
3. When deciding where to mount the fan, be sure that there is at least 30 inches(76 cm) of space
between the fan and any wall or other obstruction that the fan blades could collide with. The
greater this distance, the more effective the air flow produced.After the fan is mounted, be sure
that the blades are no less than 7ft(2.1 m) above the ground.
4 . The anchor point for the fan must be able to support a weight of at least 100 pounds(45 kg). If
mounting on a ceiling junctionbox, be sure that the fan is adequately supported to prevent
loosening or turning.
5. The fan's electrical connection must be "grounded" (the fan's ground cable connected to the
installation's grounding network) in order to avoid any branching that may be dangerous to
people.
6. Do not connect the fan's power supply to any dimmers,potentiometers, or light switches, as it
will cause the fan tomalfunction and/or will damage the motor. The fan must be directly
connected to a properly protected installation circuit(magnetothermal differential switch with the
adequate size for the fan's consumption and technical specifications).Only use the fan's control
to turn it on or stop it.
7. It is recommended to not use these types of fans along with gas installations simultaneously in
the same room.
8. The fan must be not be moving and must have come to a complete stop before changing its
direction of rotation.This will prevent damage to its motor and to the control unit, when
applicable.
9. Do not insert anything that could hit the fan's blades into its pathway while it is moving, as this
could cause damage to people, can damage the blades, and can offset the balance of the unit,
causing vibrations and wobbling.
10. After installing the fan, ensure that all fastenings aresecure and tightened in order to avoid any
noise caused by loose elements.
11. Due to the fan's movement, certain fastenings may become loose. Check all fastenings twice
per year at a minimum in order to ensure that they are sufficiently tight. If necessary, they must
be retightened.
12. The motor housing can be cleaned with a soft brush or a lint-free cloth to avoid scratching the
surface. Clean the blades with a lint-free cloth. Important: Turn off the main power supply before
starting any maintenance. Do not clean the fans with water or a damp cloth.
Note: The important warnings and instructions indicated in this manual are not
guaranteed to cover all possible conditions and situations that may occur. It
must be understood that common sense, precaution, and care are factors that
cannot be included in all products. These factors can and must only be provided
by the user who maintains and enjoys this fan.
