This will remove any dirt deposits that may have built up in the exchanger. If rinsing with clean water is not sufficient, the exchanger can also be cleaned by circulating a cleaning agent approved by Danfoss (e.g. Kaloxi cleaning fluid) through the exchanger. Kaloxi cleaning fluid is environmentally friendly and can be disposed off through the standard sewer system. - Page 21 Please note that the connections may feature EPDM gaskets! There- fore, it is important that you DO NOT OVERTIGHTEN the pipe connections. Overtightening may result in leaks. Leaks caused by over-tightening or failure to retighten connections are not covered by the warranty. 21 21 Danfoss District Energy VI.GP.U2.02 DKDHR...
