Installing uPVC vertical sash windows... Cill pre-attached to frame?

I've received 2 Spectus quickslide sash windows and was pleasantly surprised to see they come fully preassembled.

This includes the 152mm cill - it is screwed to the bottom of the frame. Initially I thought that was just to hold it in place for transport, but it's fully sealed as well.

I'd been expecting to screw the cill into the wall, have I got this wrong and the screws only go through the sides, so I can just push the entire unit into my aperture as-is?
