- Read all instructions before installing or operating this appliance.
- 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.

3. Package Contents

- Mesh Filter(s)
- Non-Ducted Conversion Kit (for recirculation)
- Two 40-Watt Incandescent Lights (pre-installed or included)
- Instruction Manual

4. Setup and Installation
Proper installation is crucial for the performance and safety of your range hood. It is recommended that installation be performed by a qualified professional.
4.1 Mounting Height
Install the hood so that the bottom of the unit is positioned 24 to 30 inches above the cooking surface. The exact mounting height will be determined by your ceiling height and personal preference, ensuring optimal capture of cooking fumes.
4.2 Ducting Options
The Broan RM503604 is designed for both ducted and non-ducted (recirculating) installations.
- Ducted Installation: The 35-7/16-inch unit with telescopic flues is designed to fit 8-foot to 9-foot ceilings with a 6-inch round duct. For ceilings up to 10 feet, optional ducted flue extensions can be purchased separately. Ensure all ductwork is properly sealed.
- Non-Ducted (Recirculating) Installation: A non-ducted kit and charcoal filter are included for indoor exhaust recirculation. This option is suitable when external venting is not feasible. The charcoal filter helps remove odors from the air before it is returned to the kitchen.
4.3 Electrical Connection
The unit operates on 120 Volts. Ensure the electrical supply meets the requirements and is installed by a licensed electrician according to local codes.

5. Operating Instructions
Your Broan RM503604 range hood is designed for ease of use with intuitive controls.
5.1 Fan Operation
The hood features a multi-speed slide control for fan operation. Slide the control to select one of the 4 available fan speeds to match your cooking needs. The fan has an airflow capacity of 290 CFM.
5.2 Heat Sentry Feature
The integrated Heat Sentry feature automatically detects excessive heat above the cooking surface. When high heat is detected, the system automatically adjusts the blower speed to its highest setting to ensure efficient removal of smoke and odors, providing an added layer of safety and convenience.
5.3 Lighting
The hood is equipped with dual 40-watt incandescent lamps. Use the dedicated light switch to turn the lights on or off, providing illumination for your cooking area.
6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your range hood.
6.1 Cleaning the Grease Filters
The mesh grease filters are designed to capture grease particles from cooking fumes. These filters are dishwasher-safe and feature a quick-release latch for easy removal. Clean them regularly (e.g., monthly, or more frequently depending on cooking habits) to prevent grease buildup, which can reduce airflow and pose a fire hazard.
- Ensure the hood is turned off and cool.
- Locate the quick-release latch on each filter.
- Press the latch and carefully pull down the filter to remove it.
- Wash the filters in a dishwasher or by hand using hot water and a mild detergent.
- Allow filters to dry completely before re-installing.
- Align the filter with the slots and push up until the latch clicks into place.
6.2 Replacing Charcoal Filters (Non-Ducted Installation)
If your hood is set up for non-ducted (recirculating) operation, the charcoal filters will need periodic replacement. Refer to the specific instructions included with your non-ducted conversion kit for replacement frequency and procedure. Typically, charcoal filters should be replaced every 3-6 months depending on usage.
6.3 Cleaning Exterior Surfaces
The stainless steel exterior can be cleaned with a soft cloth and a non-abrasive stainless steel cleaner. Always wipe in the direction of the grain to avoid scratching. Avoid using abrasive pads or cleaners that contain bleach.
6.4 Replacing Light Bulbs
To replace the 40-watt incandescent bulbs, ensure the power to the hood is off. Carefully remove the old bulb and screw in a new one of the same type and wattage.
