The fan is designed for wall or ceiling mounting. For electrical connections, it is strongly recommended to consult a qualified electrician to ensure compliance with all safety standards and regulations.
4.1. Pre-Installation Checks
- Verify that the power supply matches the fan's specifications (220-240V, 50Hz).
- Ensure the installation location allows for proper airflow and maintenance access.
- Confirm that the wall or ceiling material can support the fan's weight and allow for secure mounting.
- Prepare a circular opening of 100 mm diameter for the duct connection.
4.2. Mounting Steps
- Disconnect Power: Turn off the main power supply at the circuit breaker before starting any electrical work.
- Mark Drilling Points: Use the fan's mounting plate as a template to mark the drilling points on the wall or ceiling.
- Drill Holes: Drill holes at the marked points and insert the provided wall plugs.
- Electrical Connection: Connect the electrical wires to the terminal block inside the fan unit. Ensure correct polarity (Live, Neutral, Earth if applicable). Refer to the wiring diagram provided with the product packaging.
- Mount the Fan: Secure the fan unit to the wall or ceiling using the screws from the fixing kit.
- Install Backdraft Damper: Ensure the backdraft damper is correctly positioned to prevent reverse airflow.
- Restore Power: Once installation is complete and all connections are secure, restore power to the circuit.

5. Operating Instructions
The EQUATION SLIM Bathroom Fan operates automatically based on its integrated humidity sensor and timer.
5.1. Humidity Sensor Adjustment
The humidity sensor can be adjusted to activate the fan when the ambient humidity level exceeds a set threshold. The adjustable range is typically between 60% and 90% relative humidity.
- To adjust, carefully remove the front cover of the fan.
- Locate the humidity adjustment dial (often marked with a '%' symbol).
- Turn the dial clockwise to increase the humidity threshold (fan activates at higher humidity) or counter-clockwise to decrease it (fan activates at lower humidity).
- Replace the front cover securely.
5.2. Timer Adjustment
The timer function allows the fan to continue operating for a set period after the humidity level drops below the threshold or after the light switch (if wired to it) is turned off. The adjustable range is typically between 2 and 30 minutes.
- To adjust, carefully remove the front cover of the fan.
- Locate the timer adjustment dial (often marked with a 'min' or clock symbol).
- Turn the dial clockwise to increase the run-on time or counter-clockwise to decrease it.
- Replace the front cover securely.
Note: Always ensure power is disconnected before adjusting internal settings.
6. Maintenance
Regular cleaning ensures optimal performance and extends the lifespan of your fan.
- Disconnect Power: Always turn off the power supply to the fan at the circuit breaker before cleaning.
- Remove Front Cover: Carefully unclip or unscrew the front grille/cover.
- Clean Grille and Blades: Use a soft, damp cloth and mild detergent to clean the front grille and the fan blades. Avoid using abrasive cleaners or solvents.
- Clean Housing: Wipe the exterior housing with a damp cloth.
- Reassemble: Ensure all parts are dry before reattaching the front cover.
- Restore Power: Once reassembled, restore power to the fan.
Frequency: Cleaning should be performed every 3-6 months, or more frequently in dusty or high-humidity environments.
7. Troubleshooting
If you experience issues with your fan, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not turn on. | No power supply. Incorrect wiring. Humidity sensor setting too high. | Check circuit breaker and power connection. Verify wiring with a qualified electrician. Adjust humidity sensor to a lower threshold. |
| Fan runs continuously. | Humidity sensor setting too low. Timer set for a long duration. Faulty sensor/timer. | Adjust humidity sensor to a higher threshold. Adjust timer to a shorter duration. Contact customer support if issues persist after adjustment. |
| Reduced airflow or unusual noise. | Blocked grille or fan blades. Loose components. Motor issue. | Disconnect power and clean the grille and blades. Check for loose screws or parts (with power off). Contact customer support if noise persists. |
| Backdraft of cold air. | Backdraft damper obstructed or damaged. | Disconnect power and inspect the backdraft damper for obstructions or damage. Clear any blockages or replace if damaged. |
