xpelair cf20t

I was wondering if anyone could help me out a bit?

I have fitted a Xpelair CF20t direct to the mains. This means when i switch on the mains it will turn on, when i pull the cord it will speed up. However it doesn\\\'t turn off until i switch it off. What i wanted was to be able to pull the light cord and have the fan run and then when the light is pulled off the fan should remain on for the timer period. The only problem is that the fan needs to be earthed. The wires from the ceiling do not have an earth wire...any ideas? as you may be able to tell, I\\\'m not an electrician!!!

The connections on the fan are: N, L, T, LH

from your bathroom (assuming thats where the fan is) light take
A feed from the neutral to the N terminal on the fan
A feed from the switched live to the L of the fan
A feed from the permanent phase to the T & LH of the fan

The fan should run when light is on , turn light off the fan will run untill the timer over run stops.
The fan will also start/run if the humidity is high (LH).

Sorry forgot to mention the fan is in the bathroom. Also the terminals I have are N, T, Earth and LH...not as mentioned below.

I can wire it as you say below however it will not be earthed....Expelair suggest that I should earth it.

LH is permanent live, it stands for Live High(as in high speed).

You sure ?
I thought it might have been Live HUMIDISTAT

Actually it has a humidistat but in the manual it says LH as live high speed and LL as Live low speed. I have fitted it now but not to the light pull cord but just a separate switch...
