Replacing Extractor Fan

Confusedlancs · 27 Sep 2007

The pull switch in my shower room operates the light and the extractor fan.
The fan has packed up and I have bought a replacement; Vent Axia Silhouette 100T.
The problem is with the wiring. The old fan connections consisted of 2 Red wires,1 black,1 blue 1 yellow and the earth.
The new fan which is double insulated requires 3 connections L; N and Ls. I need advice on which wires to connect and what to do with the unused wires

Ok, what wires went where on the old fan. You did make a note of it, didnt you

How many cables have you got going into the fan?

Thank you TTC for your fast response.
I tried to make a note whilst the fan was in situ and I also took a photograph. Even with these I am not absolutley clear.
However the old fan had a terminal block with five connections and looking at it from left to right I see the following:
Connection 1 = Yellow wire from Main cable
Connection 2 = Black wire from fan
Connection 3 = Black wire from fan
Connection 4 = Blue wire from main cable and I think also the black wire from main cable. (Not Clear)
Connection 5 = Two red wires from main cable
Does this make sense

Even more confused

Based on what you have stated and some educated guesswork I suspect the following is correct

blue and black-->N
reds-->L
yellow-->Ls

all earths (I suspect you have two seperate earth wires running down the same sleeve) connected together with a peice of terminal block
