1. Preface Water quality instructions 1.2.2. Existing installations Take appropriate measures if the quality of the central heating water in an existing installation turns out to be inadequate. Installing a filter is one option to remove the pollution. Several types of filters are available for the purpose. Use a screen filter to trap larger dirt particles. This filter is usually installed in the full flow. Use a cloth filter to filter out finer pollution.
