b. Lower the pressure inside the circuit to the absolute value of 50 Pa for approx. 2 hours.
If, after this period of time, the pressure has not been taken to the set value (50
Pa), it means that there is a lot of humidity in the circuit or there is a leak.
c. Maintain the vacuum pump operating for another 3 hours.
If the value still hasn’t been reached after this period of time, look for the leak.
