RE-ASSEMBLY
Depending on the type of action carry out the operations described earlier in reverse order by paying special
attention to:
1)
Position the diaphragms correctly ensuring that their gaskets adhere to the relative supporting surface.
2)
Place the springs and guide washers at the centre of the threaded adjustment rods.
3)
Tighten the nuts on the adjustment screws correctly to the end of the thread. The final height between plate
and washer (A, see Figure) must be about 67 ± 4 mm for size 273 and about 104 ± 8 mm for size 375.
4)
Fit the cover after placing the rubber washer in the correct position to prevent water seepage.
5)
Tighten the cap nuts correctly.
