Why we should operate open drain valve... once free draining completed so we have to inject n2 and pressurized the system upto 5, 8 bar and after that depressurized the system,we should do same for two or three times After that purge with n2 and once system temp. goes from negative to positive so we can check LEL then we can know that our pump got fully drained and our system product has been fully removed then we can hand over the pump for maintenance.
Superb sir ji❤️
