 PERFORMANCE ORDER

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

Assembly

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