1. Instructions for Use

1.1 Installation

1. Safety First: Disconnect the main power supply before beginning installation.

2. Mounting:

   • Choose a flat, rigid surface (wall, ceiling, or window opening) with sufficient structural support.

   • Position the fan and mark the mounting holes using the frame as a template.

   • Drill pilot holes and secure the fan to the surface using appropriate screws and wall anchors (not included). Ensure the unit is level and tightly fastened.

3. Wiring:

   • Connect the fan’s power wires to a properly grounded electrical circuit, following all local electrical codes.

   • If the fan does not have a built-in switch, install a separate on/off switch in an easily accessible location.

4. Check Airflow Direction: Verify the fan is mounted to blow air in the desired direction (outward for exhaust, or inward for intake).

1.2 Operation

1. Power On: Turn on the power at the wall switch or circuit breaker. The fan will start running at its fixed speed.

2. Operation Modes:

   • Exhaust Mode: The fan pulls stale, hot, or contaminated air out of the room.

   • Intake Mode (if reversible): Some models allow reversing the motor to draw fresh air into the space.

3. Power Off: Turn off the power at the switch when the fan is not in use.

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. Do not use an incorrect power source.

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

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

• Installation Safety

  • Install the fan in a location where it cannot be easily accessed by children or pets.

  • Do not install the fan in areas with flammable gases, vapors, or explosive dust.

  • Ensure the fan is mounted securely to prevent it from falling or vibrating loose during operation.

• Usage Safety

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

  • Keep loose clothing, hair, and debris away from the fan blades to prevent injury or damage.

  • Do not block the fan’s intake or exhaust openings, as this can cause overheating and motor failure.

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

3. Cleaning, Maintenance & Repair

3.1 Cleaning & Maintenance

1. Regular Cleaning:

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

   • Remove the safety grille (if detachable) and use a soft brush or dry cloth to clean dust and debris from the blades, grille, and motor housing.

   • For stubborn grime, 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.

   • Check the power cord for damage or wear.

   • The motor bearings are typically pre-lubricated and sealed; do not attempt to oil them unless specified in the manufacturer’s instructions.
