Air bleeder on Alde circulation pump or lines

We used the Alde heating system on our 2016 320S Max this week in Northern Arizona.  I noticed a small perculation coming from the system that sounded like it might be bubbles of air going through the pump. Is this normal or is there an air bleeder I should attend to?
 Thanks, Jim

    As long as it is a small bubbling sound you are good to go. That is actually how I tell if my unit is coming on line. I have a 2016 unit and at first thought it might be due to low fluid but after checking a few times the fluid levels are good. May be a bit of air in the Alde but seems to have no affect on the performance. I am a big fan of the Alde system.

    The Alde system has an expansion tank behind the rear shelf, where the glycol can be heard gurgling as it passes through.
    It also functions as a bladder reminder for my DW.  :s

    It sounds like a babbling brook that puts me to sleep ;)

    Thanks for the responses. The heating system works fine. Better than fine actually. The bubbling is very mild, like a small brook far away. Was just over-reacting I guess. I will double check fluid level to be sure.    Jim

    The expansion tank also gets rid of excess air in the lines (supposedly). Somewhere in the manual (I swear I read it), it said that if you tip the T@B so the tank is higher than the Alde, it'll help get rid of some trapped air. Also, turning the pump down a bit will stop the heavy bubbling. Some T@Bs have their expansion tanks in different areas (front or back). Make sure you know where it is!! :)
