cpr Bak Pak2 R+ skimer

Hi,
I have just bought the skimmmer, but want to install in my sump, rather than hang on the side (limited space). is this feasable? I notice that the footprint isn't that wide to stand up. I was told they have an accesory for installing it in sump but can't find it on the website accessories page.
the reason I ask is that my sump water level is fairly low to accommodate a small disaster (with out overl flowing in case of power failure or pump return failure).
