5. Operating Instructions
The Kair Smart Extractor Fan offers various operating modes to suit your ventilation needs.
5.1. Speed Options
- Off: Fan is not running.
- Trickle (Constant Flow): Default operation for continuous low-level air extraction. This maintains a baseline air exchange.
- Comfort Boost (Automatic): Activated by the humidity sensor or a run-on timer. The fan increases speed when high humidity is detected.
- Boost (Manual): Activated by the pullcord or a switched live connection. Provides immediate high-speed extraction.
5.2. Humidity Sensor Operation
The integrated humidistat intelligently responds to increases in ambient humidity. When a significant rise in humidity is detected (e.g., during a shower), the fan will automatically switch to Comfort Boost mode to rapidly reduce moisture levels. The fan will return to trickle mode once humidity levels normalize. The blue light indicator on the fan will illuminate when the fan is running on boost due to the humidity sensor or switched live.
5.3. Timer Function
The timer function allows you to set how long the fan continues to operate in boost mode after the activating condition (e.g., light switch off, humidity drop) has ceased. This is particularly useful for ensuring adequate ventilation after activities like showering or cooking.
5.4. Pullcord Activation
The pullcord provides a manual override to activate the fan's boost mode. Pull the cord to initiate high-speed extraction. Ensure the blue light is off before replacing the cover if you have adjusted the pullcord position during installation.
6. Maintenance
The Kair Smart Extractor Fan is designed for low maintenance. It features a filter-less design, eliminating the need for filter replacements.
- Cleaning: Periodically clean the exterior of the fan with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Internal Cleaning: If internal cleaning is required, disconnect power at the mains. Carefully remove the magnetic front cover. Gently wipe away any dust accumulation from the impeller and internal surfaces. Ensure all parts are dry before reassembling and restoring power.
7. Troubleshooting
If you encounter issues with your Kair Smart Extractor Fan, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan not operating. | No power supply; magnetic cover not correctly aligned; internal fault. | Check mains power supply. Ensure the magnetic cover is securely in place and correctly aligned. If the issue persists, contact support. |
| Fan running continuously on boost. | High humidity detected; pullcord activated; switched live continuously on. | Check humidity levels in the room. Ensure the pullcord is in the 'off' position. Verify switched live connection. Adjust humidity sensitivity settings if necessary. |
| Fan is noisy. | Debris in impeller; loose mounting; normal boost operation sound. | Disconnect power and inspect the impeller for debris. Ensure the fan is securely mounted. Note that boost mode will naturally be louder than trickle mode. |
| Humidity not reducing effectively. | Humidity sensor setting too low; fan speed too low; insufficient air exchange. | Adjust the humidity sensor trigger level to a lower percentage. Increase the fan speed settings for boost mode. Ensure there are no obstructions to airflow. |
If you have any installation questions or require further assistance, please contact Kair support.
