Congrats on the purchase, it makes dev'ing colour much easier.
However, beware, it's a bit more of a physical process than B&W, I find. I've developed about 15 rolls in mine so far. Because the timings are much more critical than B&W, it feels like your deejaying at nightclub with all the moving about, tweaking, and changing things. Here's some thoughts off the top of my head:
The tanks: make sure you pop the rubber 'popper' lid down before rotating. The popper lid needs to be pushed down because of the build up of pressure in the tank when rotating. I've forgotten (once) and the lid blew off spilling Blix everywhere. Beware, even when I have popped the little rubber part of the lid down, the lid has blown off as well. So, until your confident, keep near the rotating tank for the first few go's, just incase it decides to pop off. It happened to me a few time always when doing the Blix part.
I reckon part of the problem of the above was that the temperature control was slightly off (too high) on my machine. So, make sure you've got a thermometer in the chems (particularly dev) and don't just rely on the temperature dial as being correct.
Make sure you've fasten the lid down tight when putting your rolls in. For similar reasons as my first point above. If it can come off, it will.
Remember that your chems are to go back into the correct bottles. I was so used to b&w developing early on, I forgot and chucked some of the colour chemicals away, absentmindedly. (Mainly the stabiliser as the last process because you're taking the film out of the tank.)
Since it's standardised times, try and get as many rolls done in one tank/session.
Make sure you've got the guide rail in the correct place for the tank's rotation. It's a thin strip of plastic with wheels that sits inside the water near the rotator mechanism.
There's more but that's all I can think of right now. Will add more if others don't before me. Good luck!
