1. The order of installation could be represented better, that's with the numbers, unfortunately, become a little confused
2. When installing in a flush-mounting box you can not see what you're doing, why do not you can also see that this black holding fork when attaching most past attacks. As a result, the stuck of the operating lever and the water continues to run without it ever closes. In my case I was able to finally unmask with a small mirror those holding fork as malefactor by many to install and remove.
My suggestion, please this holding fork in the instructions concerning specially mention these problems to other customers to avoid this frustration I had this at first.
Here is why one of the five-star rating is entschwommen through the cistern next to sewage treatment plant. ;-)
