Is this RODI setup correct?

[-=James=-]

Help! After setting up my AquaSafe 7 stage 100GPD RODI unit, I turned on the water just to find that it shoots right back out of the reject tube (Yellow) with lots of pressure.
Not a single drop goes out the RODI tube. The cartridges are used but still have good life left.

Is this set up correctly? Any thoughts?

Heres a pic: Red is water in, Yellow is waste water, Blue is RODI water
