DIY - Unblocking the motor on PrimAX and CompAX pumps

After a long period of standstill, it can happen that the heating pumps are blocked. Yannick Joch, HVAC Product Manager, shows you how you can unblock our PrimAX and CompAX pumps in this case so that the heating runs smoothly again.
A little tip: To prevent blockages from occurring after a longer break, we recommend running the pump briefly every 2-3 weeks.
