Close the flap and set a pressure of −400 Pa by means of the bypass valves. Open the flap and fill the trap with water. Close the flap and slowly open after about 5 s. Repeat this procedure until the trap no longer loses water, but no more than 5 times. Remove 8 mm of water height; this corresponds to the reduction in the depth of water seal due to evaporation over a period of disuse. Subject the trap on the outlet side to a positive pressure such that flow of air just occurs. Record the pressure. With the flap closed, set the desired negative pressure with the bypass valves, and read the manometer. The sensors in the trap are connected to the recording device. When the flap is closed rapidly, the desired vacuum pressure is established immediately. SIST EN 1253-1:2015
