Bathroom extractor fan wiring colours? Vents 100 MTP

[Klaus_K]

I have just bought a new extractor fan to replace one that has gone belly up in my bathroom (Zone 3).

Unfortunately, the new fan has two connectors that are coloured white and blue - but I don't know which is live and which is neutral.

The white side does feed to the red pole of an LED, but I'm not 100% sure if that is enough proof.

The manual doesn't provide any indication of what the colours mean.

The fan is a "Vents 100 MTP", if that helps.

Thanks for any info.

Doesnt the instructions show a layout of how it should be connected? It should do.

But it doesn't

Can you post a photo of the terminations?
How many wires do you ahve to connect up, is it 2 or 3 (plus earth)

As you can see, it has one blue connector and one white connector. As I already mentioned, the white connector seems to be connected to the red side of the LED.

My supply has a neutral, a switched live and an unswitched live, plus earth.

I just want to connect the neutral plus unswitched, since the fan already includes a PIR sensor to control when the fan gets switched on, plus a timer that controls how long it stays on.

Are you sure that's an LED and not a neon?

Because if it's an LED my first reaction would be that you've got an ELV fan, not an LV one.

In any event, failure to provide adequate installation instructions is an offence under the Sale and Supply of Goods to Consumers Regulations 2002, so if you want to return it for a refund you can.

If you want to keep it, and you're sure it is LV not ELV then it won't matter which way round you connect it.

I think it must be a neon - my supplier has now got back to me and said it doesn't matter which way round it is connected - and a mains-voltage LED would be unusual in any case.

I can confirm that the fan is mains voltage - 220-240v.

a mains-voltage LED would be unusual in any case.

Which is why I asked if you were sure, and why I said if it was an LED I doubted that it would be a LV fan....

Now to wire the thing up and see how long we can take it switching on whenever we walk into the room

Next step will be to use the switched live, I guess.
