Manrose inline extractor fan

[andyneile]

Hi Guys
I have changed to an inline extractor fan and chose a non timer manrose model from screwfix. I have wired it using the switched live and the neutral and blocked off the the live. The fan is really weak but I have read online it has two speed settings and I hope it is on the lowest setting. I have no instructions and was wondering how I change the speed. I will appreciate any advice.
Cheers

What model number is the fan, and are you sure it is two speed.

It is this one:

it claims to have two speeds and I really hope i am not on the highest setting. Thanks for helping.

Have you examined the innards of the fan - the terminal block area? There might be an unmarked switch. Try it.

I'll have another look in the morning. Really disipointed it came with no instructions !!!

The model number is mf100s.

Check the other unused terminal, if its labelled let us know what is written. It could be that this is the terminal to be used for the higher speed.

Edit: actually, let us know what is written on all the terminals on the fan.

I think it is the wiring that increases the speed. I currently have my switched live in the L slot, my neutral in N1 and N2 empty. I think i need to put the unswitched live (currently blocked off) in either N1 or N2 but am not sure which one. Please help.

Why not email manrose and they will send you a wiring diagram, worth looking on the inside of the terminal box cover, there may be a drawing on it.
quessing and putting Lives into N terminals is not a good idea.
