2. Important Safety & Usage Precautions

• Electrical Safety

  • Always disconnect power before installing, cleaning, or servicing the fan.

  • Ensure the power supply voltage matches the fan’s rated voltage.

  • The fan must be properly grounded to prevent electric shock hazards.

  • Do not operate the fan if the power cord is damaged, frayed, or exposed.

• Installation Safety

  • The fan must be securely mounted to prevent loosening or falling due to vibration.

  • Ensure there is no blockage on both the intake (indoor) and exhaust (outdoor) sides of the fan.

  • If installed in a kitchen, avoid positioning the fan directly above high-heat cooking surfaces to prevent grease buildup or fire risks.

• Usage Safety

  • Never insert fingers, tools, or other objects through the safety grille while the fan is running.

  • Do not use the fan to exhaust flammable, corrosive, or explosive gases unless it is rated for hazardous environments.

  • If the fan emits unusual noise, smoke, or a burning smell, turn it off immediately and disconnect power.

1. Regular Cleaning:

   • Disconnect power and wait for the blades to stop completely.

   • Use a soft brush or dry cloth to clean dust, grease, and debris from the grille, blades, and frame.

   • For stubborn grease buildup (e.g., kitchen use), use a slightly damp cloth with a mild detergent. Never immerse the motor housing in water.

2. Preventative Maintenance:

   • Every 3–6 months, inspect and tighten all mounting screws and grille fasteners to prevent loosening from vibration.
