Abode Mixer Tap - Dripping!

[Oddsox]

Hi,
I've just installed a new Abode Mixer Tap in my kitchen. :D
It is a monobloque type.
It has a "pure water" feature on the cold supply.
Unfortunately, the cold supply has a constant drip. :(
Do any of you know how to take this type of tap apart?
Any help gratefully received!
Thanks,
O
