Utility at a level higher
than the system

lic part clogged.
1. As the suction depth increases
the hydraulic performance of
the product decreases (
De-

).
Check whether the suction
depth can be reduced. Use
a suction pipe with a larger
diameter (but never smaller
than 1”).
2. Check the suction pipe, find the

Expansion vessel
empty (insufficient
air pressure) or has
broken diaphragm.
Check the air pressure through
the valve in the technical compart
-
ment. If water comes out when
checking, the vessel is broken:
assistance service. Otherwise
restore the air pressure according
to the equation par. 1.2.
