1. Introduction
This manual provides essential information for the safe installation, operation, and maintenance of your Nutone 30" 210 Max CFM White Range Hood, Model NU230WW. Please read this manual thoroughly before installation and use, and retain it for future reference.
The Nutone range hood is designed to effectively remove smoke, steam, grease, and cooking odors from your kitchen, ensuring a cleaner and more comfortable cooking environment. It features a 2-speed rocker switch, an aluminum grease filter, and is compatible with both ducted and non-ducted installations (with an optional charcoal filter).
2. Safety Information
WARNING: To reduce the risk of fire, electric shock, or injury to persons, observe the following:
- Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards, including fire-rated construction.
- Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent back-drafting. Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.
- When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
- Ducted fans must always be vented to the outdoors.
- Do not use this unit with any solid-state speed control device.
- This unit is intended for general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
- To reduce the risk of fire and to properly exhaust air, be sure to duct air outside – Do not vent exhaust air into spaces within walls or ceilings, attics, crawl spaces, or garages.
- Always disconnect power from the unit before servicing or cleaning.
CAUTION:
- For indoor use only.
- To reduce the risk of fire, use only metal ductwork.
- To reduce the risk of range top grease fire:
- Never leave surface units unattended at high settings. Boilovers cause smoking and greasy spillovers that may ignite. Heat oils slowly on low or medium settings.
- Always turn hood ON when cooking at high heat or when flambéing food.
- Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
- Use proper pan size. Always use cookware appropriate for the size of the surface element.

4. Operating Instructions
Your Nutone Range Hood is designed for simple and efficient operation.
Figure 4.1: Front view of the Nutone Range Hood, highlighting the control panel area.
4.1 Fan Operation
- The range hood is equipped with a 2-speed rocker switch located on the front control panel.
- To turn the fan ON to the low speed setting, press the rocker switch to the first position.
- To increase the fan speed to high, press the rocker switch to the second position. At high speed, the fan provides up to 160 CFM (Cubic Feet Per Minute) of airflow, with a maximum CFM of 210.
- To turn the fan OFF, return the rocker switch to the neutral (center) position.
4.2 Lighting Operation
- The range hood features a light socket for a 75-watt bulb (not included).
- The light is controlled by a separate push button switch on the control panel.
- Press the button once to turn the light ON.
- Press the button again to turn the light OFF.
For best results, turn on the range hood a few minutes before cooking to establish an airflow pattern, and leave it on for a few minutes after cooking to clear any remaining smoke or odors.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Nutone Range Hood. Always disconnect power to the unit before performing any maintenance.
5.1 Cleaning the Exterior
- The exterior of the range hood is finished in white and is designed to be easy to clean.
- Wipe surfaces regularly with a soft cloth dampened with mild detergent and warm water.
- Do not use abrasive cleaners, steel wool, or scouring pads, as these can scratch the finish.
- Dry thoroughly after cleaning.
5.2 Cleaning the Aluminum Grease Filter
The aluminum grease filter should be cleaned regularly, depending on cooking frequency and type. A dirty filter can reduce airflow and increase fire risk.
- Remove the Filter: Locate the aluminum grease filter beneath the hood. It typically has a small latch or spring mechanism. Gently push or pull the latch to release the filter and slide it out.
- Clean the Filter: The filter can be washed by hand in hot water with a mild dish soap, or placed in a dishwasher. For stubborn grease, soak the filter in hot, soapy water before scrubbing with a non-abrasive brush.
- Dry and Reinstall: Ensure the filter is completely dry before reinstalling it. Slide the filter back into its slot until it clicks securely into place.
5.3 Replacing the Charcoal Filter (Non-Ducted Installations Only)
If your range hood is installed in a non-ducted configuration, it uses a charcoal filter (Nutone part 41F) to remove odors. This filter is not washable and must be replaced periodically, typically every 3-6 months depending on usage.
- Remove Old Filter: Disconnect power. Locate the charcoal filter, usually positioned above the grease filter or near the fan motor. Follow the instructions in your full installation guide for specific removal steps.
- Install New Filter: Place the new Nutone charcoal filter 41F into position, ensuring it is securely seated.
- Restore Power: Reconnect power and test the unit.
