Utility at a level higher
than the system
restarting pressure
level (par. 3.2).
Increase the system restarting
pressure level by increasing SP or
decreasing RP.

1. Leak in the
system.
2. Impeller or hydrau-
lic part clogged.
3. Air getting into the
suction pipe.
4. Faulty ow sensor
1. Check the system, nd and
eliminate the leak.
2. Dismantle the system and
remove the obstructions (assis-
tance service).
3. Check the suction pipe, nd
and eliminate the cause of air
getting in.
4. Contact the assistance centre.

1. Suction depth too
high.
2. Suction pipe
clogged or diame-
ter insufcient.
3. Impeller or hydrau-
lic part clogged.
1. As the suction depth increases
the hydraulic performance of
the product decreases. 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, nd the
cause of choking (obstruction,
dry bend, counterslope, …) and
remove it.
3. Dismantle the system and
remove the obstructions (assis-
tance service).

Expansion vessel
empty (insufcient
air pressure) or has
broken diaphragm.
Check the air pressure in the ex-
pansion vessel. If water comes out
when checking, the vessel is bro-
ken: assistance service. Otherwise
restore the air pressure according to
the equation par. 1.2.

Air pressure in the ex-
pansion vessel higher
than the system
starting pressure.
TCalibrate the expansion vessel
pressure or congure the parame-
ters SP and/or RP so as to satisfy
the equation par.1.2.
