FAQs
What is SELV and why is it important?
SELV stands for Safety Extra Low Voltage. It means the fan operates at 12V, which is significantly safer in wet environments like bathrooms and WCs compared to standard mains voltage.
Do I need a separate transformer for this fan?
Yes, as this is a SELV model operating at 12V, it requires a compatible 12V transformer to be installed. This may need to be purchased separately.
Can this fan be installed in Zone 1 of a bathroom?
Yes, the Envirovent Silent 100 is IP57 rated, making it suitable for installation in Bathroom Zones 1 or 2.
How do I adjust the run-on timer?
The timer is typically adjusted via a small screw on the fan unit itself. Consult the installation manual for precise instructions on setting the desired run-on duration.
What is the power consumption of this fan?
The fan has a power consumption of 13W.
How often should I clean the fan?
It is recommended to clean the fan grille monthly or as needed to maintain optimal airflow. More thorough cleaning of internal components should only be done by a qualified professional.
What is the sound level of the fan?
The fan operates very quietly, with a sound output of 26.5dB(A) at 3 meters.
Troubleshooting
Fan does not turn on
Check the 12V power supply and ensure the transformer is functioning correctly. Verify all electrical connections are secure.
Fan is noisy
Ensure the fan is securely mounted and that no obstructions are present in the ducting or on the fan blades. Check if the backdraught shutter is stuck.
Low airflow
Clean the fan grille and check ducting for blockages. Ensure the fan is correctly oriented for optimal airflow.
Timer not working
Confirm the connection to the switched live (if applicable to your setup) and verify the timer adjustment screw is set correctly.
