10/12/14/16 Inch Circular Axial Flow Industrial Fan,high-speed Wall-mounted Ventilation Exhaust Fan for Kitchen ,warehouse,workshop

1. Instructions for Use

1.1 Installation

1. Safety First: Turn off the main power supply at the circuit breaker before starting installation.

2. Mounting:

   • Choose a suitable location (wall, ceiling, or duct opening) with a sturdy surface capable of supporting the fan’s weight and vibration.

   • Align the fan’s mounting holes with the pre-drilled holes, then secure it with the provided screws and washers.

   • If using with ductwork, connect the ducts to the intake/exhaust ends of the fan using clamps or adapters for a secure fit.

3. Wiring:

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

   • Install a dedicated on/off switch for safe and easy operation.

4. Test Run: Restore power briefly to confirm the fan operates smoothly and airflow direction is correct (intake or exhaust).

1.2 Operation

1. Power On: Turn on the dedicated switch to start the fan. The unit will run at its rated speed to circulate or exhaust air.

2. Airflow Adjustment: If your model has adjustable speed settings, use the control to select the desired airflow volume.

3. Shutdown: Turn off the power at the switch when the fan is not in use, or before performing maintenance/cleaning.

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 incompatible power source.

  • 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.

  • Do not install the fan in environments with flammable gases, vapors, or explosive dust unless the fan is specifically rated for such hazardous locations.

  • Ensure at least 30cm of clearance around the intake and exhaust openings to avoid airflow blockage.

• Usage Safety

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

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

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

  • Do not use the fan to blow flammable, corrosive, or hazardous materials unless the fan is rated for such use.

3. Cleaning, Maintenance & Repair

3.1 Cleaning & Maintenance

1. Regular Cleaning:

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

   • Use a soft brush or dry cloth to remove dust and debris from the grille, blades, 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 signs of wear, fraying, or damage.

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

   • Inspect the fan for signs of corrosion, especially if used in humid or high-moisture environments
