PERFORMANCE ORDER

1. Turn off bolts.
2. Remove valves (13), (24), (86) and the screen (33a).
3. Fix the case of valves (A) and the case of a damper (V) together and turn them.
4. Carefully lift the case of a damper (V) with an intermediate plate.
5. Remove all 19 balls (14).
6. Remove the valves filtering and switching fingers.
7. Turn off a side cover from the case of valves.
8. Adjust pressure at full opening of a butterfly valve.

Assembly

Assembly is carried out as it should be, the return to dismantling. Tighten bolts of fastening (arrow) so that both parts of the case could not move relatively each other.
