1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Zomagas CFZMG13 Range Hood Charcoal Filters. These filters are designed to convert compatible range hoods into ductless (recirculating) systems by effectively absorbing cooking odors and smoke particles. Please read these instructions thoroughly before installation and retain them for future reference.

5. Installation Instructions
Installation of the Zomagas CFZMG13 charcoal filters is designed to be straightforward and requires no special tools.
- Power Disconnection: Ensure the range hood is completely powered off and unplugged from the electrical outlet before beginning installation.
- Access Filter Area: Remove any existing grease filters or covers to access the motor housing area within the range hood. Refer to your range hood's specific manual for instructions on accessing this area.
- Position the Filter: Align the charcoal filter with the motor housing. The filter is designed to fit directly onto the motor.
- Twist and Lock: Gently push the filter onto the motor and twist it clockwise until it locks securely into place. You should feel or hear a click indicating it is properly seated.
- Repeat for Second Filter: If your range hood requires two filters (as is common for these models), repeat steps 3 and 4 for the second filter on the other motor.
- Reassemble: Replace any removed grease filters or covers.
- Restore Power: Plug the range hood back into the electrical outlet and restore power.

6. Operation and Replacement
Once installed, the charcoal filters work automatically with your range hood's fan to filter air. They are crucial for effective odor absorption in ductless range hood configurations.
Filter Replacement Schedule
Charcoal filters have a limited lifespan and must be replaced regularly to maintain optimal performance. It is recommended to replace the Zomagas CFZMG13 filters every 2 to 4 months. However, replacement frequency may vary depending on:
- Cooking Habits: Frequent cooking, especially with strong odors or high grease, will require more frequent replacement.
- Type of Cooking: Frying and grilling produce more smoke and odors, shortening filter life.
- Ventilation Usage: The more often the range hood is used, the faster the filters will become saturated.
A noticeable decrease in odor absorption or increased noise from the range hood fan can indicate that the filters are saturated and need replacement.
7. Maintenance
The Zomagas CFZMG13 charcoal filters are maintenance-free beyond regular replacement. They cannot be cleaned or regenerated.
Disposal
Dispose of used charcoal filters according to local waste disposal regulations. They are generally safe for household waste.
8. Troubleshooting
- Filter does not fit: Double-check the compatibility list in Section 4. Ensure you have the correct model number for your range hood.
- Odor absorption is poor: This indicates the filters are likely saturated and need to be replaced. Refer to Section 6 for replacement guidelines.
- Charcoal particles observed: It is normal for some fine charcoal dust to be present, especially upon initial handling. If excessive particles are falling, ensure the filter is not damaged and is securely installed. Clean any fallen particles with a damp cloth.
- Increased noise from range hood: While filters can slightly restrict airflow, a significant increase in noise might suggest the filters are heavily saturated and impeding airflow, requiring replacement.
