5.1 Adjustable Speed
The fan features six adjustable speed levels, allowing you to optimize airflow and noise levels according to your needs. The available speeds range from 1050 RPM to 2220 RPM. Consult the internal adjustment mechanism (typically potentiometers or switches accessible after removing the front cover) to select the desired speed setting.
5.2 Humidity Sensor (Hygro)
The integrated humidity sensor automatically activates the fan when the ambient humidity exceeds a preset threshold. This threshold can typically be adjusted (e.g., from 30% to 80% relative humidity) using a control knob or potentiometer located inside the fan unit. The fan will run until the humidity level drops below the set point.
5.3 Timer Function
The timer function allows the fan to continue operating for a set period after it has been manually switched off or after the humidity level has dropped below the sensor's threshold. The timer duration is adjustable, commonly offering settings such as 3, 5, 10, 15, or 20 minutes. This setting is usually adjusted via a control knob or potentiometer within the fan unit.
6. Maintenance
Regular maintenance ensures the efficient and safe operation of your Cata UC-10 fan.
6.1 Cleaning
- Disconnect Power: Always ensure the power supply to the fan is disconnected before cleaning.
- Remove Front Cover: Carefully detach the extra-flat front cover.
- Clean Components: Use a soft, damp cloth to wipe down the front cover and the fan blades. Avoid using abrasive cleaners or solvents. Ensure no water enters the electrical components.
- Reassemble: Once all parts are dry, reattach the front cover securely.
It is recommended to clean the fan at least once every six months, or more frequently in dusty or high-humidity environments.
