Checking the Piping Caution Use only under conditions in which no water hammer will occur. The impact of water hammer may damage the product, leading to fluid discharge, which may cause burns or other injury. Check to make sure that the pipes to be connected to the product have been installed properly. -
Page 7: Operation
Operation Principles of air and condensate discharge: At start-up, open the bypass valve to remove any initial condensate or air at 100°C or less. (This step must be performed in order to ensure smooth start-up.) Air binding occurs when the inflow of steam is accompanied by the inflow of air during normal operation. -
