Today in lab we had a problem with "C" pant. We turned on the air water pressure, then we turned on the valve Fv300, and then we turned on the valve water and turned on PI304. We followed the pressure meter. We sat for a quarter of an hour to make sure that all the flors came down to the dry, and then we waited for 12 minutes to make sure that all the flors came down to the filters. We made sure that all the flors went down to the filters. We called the value followed the flors, then we opened the value followed the tank T-301 degrees 5% because the pain came down on the tank T 301.
