Set and anchor dryer in position. Machine should be level to assure proper steam circulation. 2. To prevent condensate draining from headers to dryer, piping should have a minimum 12” above respective header. Do not make steam connection to header with a horizontal or downwardly facing tee or elbow. 3. Whenever possible, horizontal runs of steam lines must drain, by gravity, to respective steam header. Water pockets, or an imporperly drained steam header will provide wet steam, causing improper operation of dryer. If pockets or improper drainage cannot be eliminated, install a by-pass trap to drain condensate from the low point in the steam supply header to the return. 4. In both steam supply and steam retyrn line, it is recommended that each have a 1” union and 1” globe valve. This will enable you to disconnect the steam connections and service the dryer while your plant is in operation. 5. Before connecting trap and check valve to dryer, open globe valve in steam supply line and allow steam to flow through dryer to flush out any dirt and scale from dryer. This will assure proper operation of trap when connected. 6. After flushing system, install bucket trap (with built-in strainer) and check valve. For successful operation of dryer, install trap 18” below coil and as near to the dryer as possible. Inspect trap carefully for inlet and outlet markings and install according to trap manufacturer's instructions. If steam is gravity returned to boiler, omit trap but install check valve in return line near dryer. 7. Install union and globe valve in return line and make final pipe connections to return header.
