I didn't think there would be a problem. If you get air in the UAT, it means that your getting it from the main tanks. If that happens, it will happen no matter what the attitude of the collector tank is. UAT's are supposed to stay full anyway if the rest of your system functions properly, or so I thought.

.. Dan thats the way i had it figured.... and the reason for having the UAT at 45 degrees or so was to allow the air to collect in the top corner of the tank near the two fill/vent lines so you could easily bleed any trapped air off as and when necessary.
