                Dressing a radiator
                Dressing a radiator involves getting the radiator ready for hanging by putting in
                the valves, the air release valve and the plug. The process is as follows.

                1  Carefully remove the radiator from its packing. Inside the packing you will
                   find the hanging brackets, the air release valve and the plug – and, often,
                   small ‘u’-shaped pieces of plastic, which are to be placed on the brackets
                   where the radiator fits. These are designed to prevent the radiator from
                   rattling.
                2  Take out the factory-fitted plugs. Be careful here, especially if you are
                   working in a furnished property, as the radiator often contains a small
                   amount of water from when it was tested at the factory.

                                                                                                                469
