When examining the leak and the repair is made successfully, bringing out the nitrogen tank.Open the valve Low side High side valve parts off.Gently rotate the way Low-nitrogen gas out counterclockwise through the Compound Gauge and Gauge cable exit.Remove the vacuum pump connected by suction plugged wires Gauge.Spin valves Compound Gauge.The Rotary air and absorb moisture, about 45 minutes.Note the Compound Gauge will be lower than 0 scale Vacuum is comes down to 29 inches of mercury.When the Vacuum gauge valve closed, about 15 minutes via Low and High way and lead to refrigerant filling came into it, then open the valves of Low gauge, coolant gauge pointer moves into the system until the psig.Turn off the valves of Low Vacuum gauges then carry to continue making new Vacuum again until time of not less than 45 minutes, and the needle of the gauge pointer less than 29 inches of mercury.While making the Vacuum to remove the 100-watt lamp to heat the waep Corporation. remove gas welding, heat to the condenser so that the moisture or water mist contained within the system, and it was the machine. Vacuum suction dropped.Approximately 45 minutes and when in the hands of the Vacuum gauge pointer Low way less than 29 inches of mercury, close the valve of the Low way gauges.Prepare the next refrigerant filling
