Ah, interesting, and I suspected that was the procedure including discarding the plastic undertray. Simon, I take it the old fan can be used? And would I need a valance, type Wolf Performance? And as your website is not working at the moment, what is the price, ex. VAT as I live outside the EU? If you prefer to PM me, my number is +47 90 85 11 39. Your choice.
