Safety Information

- Always disconnect power before servicing or cleaning the unit.
- Installation must be performed by a qualified technician in accordance with all local codes and standards.
- Ensure proper grounding to reduce the risk of electric shock.

- Maintain adequate ventilation in the room when the range hood is used simultaneously with gas or other fuel-burning appliances.
Setup and Installation
The Pacific Auto Clean Range Hood is designed for under-cabinet mounting. Professional installation is recommended due to the unit's weight and the precision required for ducting and electrical connections. Refer to the detailed user manual PDF for specific dimensions, cutout templates, and step-by-step instructions.
Key Installation Considerations:
- Ducting: This model uses a top round 6-inch vent exhaust. Ensure your existing ductwork is compatible or make necessary modifications.
- Mounting: Verify cabinet dimensions against hanging hole locations. For secure mounting, consider using machine screws with washers and nuts instead of wood screws, especially if cabinet walls are thin.
- Electrical Connection: The unit requires a dedicated electrical circuit. The power cord provided is approximately 12 inches long; plan your outlet location accordingly or consult an electrician for proper wiring.
- Protection Film: The stainless steel unit comes with an off-white protective film. This should be removed after installation to reveal the true finish.

Maintenance
The Pacific Auto Clean Range Hood is designed for easy maintenance, featuring a filter-less design and an auto-clean function.
- Auto Clean Function: This innovative feature simplifies internal cleaning. To use, add a small amount of cleaner and water to the designated reservoir (often a small cup or opening). Activate the auto-clean cycle, and the high-speed spinning blower blades will distribute the solution, degreasing and flushing residue into the removable grease tray. This process typically takes about 38 seconds.
- Grease Tray: The removable grease tray collects all flushed residue. Regularly empty and clean this tray to prevent overflow and maintain hygiene.
- Exterior Cleaning: Wipe the stainless steel exterior with a soft cloth and a mild, non-abrasive cleaner. Avoid harsh chemicals or abrasive pads that could scratch the finish.
- LED Lights: The LED lights are long-lasting and generally do not require replacement. If an issue occurs, consult the troubleshooting section or contact customer support.
