Illustration 16:
When fitting the bowl wall, press firmly
downwards with both hands to overcome the
resistance from the O-ring fitted on the bowl
bottom. A “clicking” sound will be heard.
Illustration 17:
If the level ring (1) and O-ring (2) have been
removed, first fit the level ring and then the O-ring
outside the level ring. Finally press down the
O-ring by pressing the cover (3) firmly with both
hands.
Illustration 18:
Check that the distance illustrated is max. 0,5
mm. If not, the reason could be:
1. The O-ring outside the level ring is not in the
downwards position or the O-ring is located
under the level ring.
2. Two washers are fitted under the centre
screw fixing the bowl to spindle.
Illustration 20:
Only tighten by hand. Never over tighten when
assembling parts.
