5.3 Start up
1. Always start up the system only with closed butterfly valve.
2. Be sure that the system is clean before starting up. Impurities may damage the
seat immediately and in addition cause a leakage of the butterfly valve.
3. The valve should be fully opened at the last flushing by cleaning the system.
4. Check the stuffing box and in case of leakage, tighten the nuts of the stuffing
box gland (
➔ Tab.4-4).
