Thank you for your inquiry, Dejan. We would recommend that you clean the filter and purge debris from the unit until water runs clean for 10-15 seconds out the purge drain.
+Greg - Please note that the DIRTMAG+ shown in the video is not available in the North American market. We do have a full line of magnetic dirt separators that you can check out on our website! Check it out here: www.caleffi.com/usa/en-us/products/search?query=dirtmag
