3. Safety Information
Always observe the following safety precautions:
- Disconnect all power to the RV's air conditioning system before performing any installation, maintenance, or troubleshooting.
- Ensure all wiring connections are secure and comply with local and national electrical codes.
- Only qualified personnel should perform electrical work.
- Do not operate the unit if any part is damaged or missing.

4. Installation
The DOMETIC 3310741.016 ADB is designed for straightforward installation. Refer to the separate, detailed installation instructions provided with your Dometic air conditioning unit for comprehensive steps and diagrams.
Important Installation Considerations:
- Roof Thickness: If your RV's roof thickness exceeds 6 inches, an extended mounting kit (Dometic part number 3101538.001) may be required to ensure proper and secure installation. Consult your installation instructions for specific measurements and requirements.
- Mounting Bolts: Ensure that the mounting bolts provided are of adequate length for your specific roof thickness. In some cases, longer bolts may be necessary to achieve a secure fit.
- Control Knob Alignment: During installation of the ceiling cover, ensure that the control knob connectors are properly aligned and adjusted to their fully extended length before attaching the knobs. This will prevent issues with knobs being difficult to turn or not fitting correctly.
5. Operation
The DOMETIC 3310741.016 ADB features intuitive manual controls for adjusting your RV's climate.
Control Knobs:
The unit is equipped with two manual rotary knobs:
- Left Knob (Fan Speed): This knob controls the fan speed of your air conditioning unit. Rotate it to select desired fan settings (e.g., Low, Medium, High, Auto).
- Right Knob (Mode/Temperature): This knob typically controls the operating mode (e.g., Cool, Fan Only, Heat - if applicable to your AC unit) and temperature settings. Rotate it to select your preferred comfort level.
Adjust the louvers on the ADB to direct airflow as needed for optimal comfort and air distribution within your RV.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your ADB.
- Cleaning: Periodically clean the exterior of the ADB with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Air Filters: Check and clean or replace the air filters (if present in your AC unit or ADB) according to your air conditioner's manual. Clean filters improve airflow and efficiency.
- Ventilation: Ensure that all air vents and grilles on the ADB are free from obstructions to maintain proper airflow.
7. Troubleshooting
