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, find the
cause of choking (obstruction,
dry bend, counterslope, ...) and
remove it.
3. Dismantle the system and
remove the obstructions (assis-
tance service).
1. Check the system, find and
eliminate the leak.
2. Service the non-return valve as
described in par. 9.3.

1-2. Prime the pump and check
whether there is air in the pipe.
Check whether the suction or any
filters are blocked.
3. Set a RM value that allows the
setpoint to be reached.
1. Contact the assistance centre.
1. Contact the assistance centre.
1. Fluid too dense. Do not use
the pump for fluids other than
water.
2. Contact the assistance centre.
1. Check the presence of the
correct supply voltage.
2. Check the section of the power
supply cables.
