Question & Answers

Should I remove the tape on the inside of the Silent HT fan?

No, this is Hydroscopic tape, it is to protect the sensor from moisture, but will allow vapour through. Removing this may damage the sensor and invalidate the warranty.

Why is my Silent extractor fan running continuously?

This may be due to incorrect wiring, please have a qualified electrician check this with the install guide and speak to the EnviroVent technical department if required. It may also be due to an incorrectly set humidity sensor (model dependant). If a humidity sensor version is fitted the sensitivity can be adjusted on the extractor fan. Adjusting clock wise will make the sensor less sensitive, anticlockwise will make the sensor more sensitive to humidity.

My Silent extractor fan will not run:

If an extractor fan will not operate, a qualified electrician will need to check the wiring, ensuring the fan is wired correctly and receiving power.

How do I get the front cover off my Silent extractor fan?

Always isolate power first. The cover can be removed by firstly pushing the small reseeded retaining point on one of the edges of the extractor fan, then slowly unclipping the rest of the cover with a small flat screw driver.

What wiring does the Silent T and HT require?

These extractor fans require a permanent live and neutral and a switch live (to trigger the fan).

Can I fit a 230V extractor fan in zones 1 or 2 of a bathroom?

Yes, as long as the circuit is protected by a 30mA RCD
