OPERATIONAL TEST (OR AFTER ANY SYSTEM OPERATION): The
low-body drain valve and any low-point drain valves should be partially
opened and then closed to drain water that might be present in the
riser. Continue this procedure until all water is released. NOTE: The
optional Series 75D Water Column Kit can be installed to automate this
