OPERATING INSTRUCTIONS
8. OPERATING RULES
If the suction phase does not begin within 120 seconds, the pump will stop automatically,
and then will make two further attempts for another 120 seconds If the pump still will
not start, it will be necessary to troubleshoot the cause of the failure
Among the possible causes are: the suction line does not draw well or is leaky; the
priming opening is not closed properly; the suction height is excessive; air cannot come
out because the delivery tube is blocked; the suction line is not equipped with an Anti-
backflow foot valve or the pump body and the suction line were not completely filled
with water when the system was first put into operation
If the pump keeps starting and stopping and water is not turned on, the delivery tube or
the connection with the pump might be leaky In either case, an act as required The
problem may also be due to a build-up of dirt inside the Hydrotronic If that is the case,
remove the Hydrotronic from the pump and rinse it thoroughly, for example with a strong
water jet from the inlet side (6)
9. WARRANTY

Red LED (3)
blinks
No water Normal water flow must be restored
Red LED (3) stays
on continuously
No automatic reset attempts
left
Disconnect the power plug and then reconnect it
Pump keeps
starting and
stopping
1 The system is leaky
(unsealed)
2 Foreign materials inside the
Hydrotronic
1 Check the system and the connection with the
pump
2 Disconnect the power plug, remove the
Hydrotronic from the pump and rinse it
thoroughly by spraying water from the inlet side
(6) - i e using a garden hose
Pump dose not
work
1 The pump may be defected
2 The Hydrotronic may be
obstructed by foreign
materials or Limescale
(calcium)
Disconnect the Hydrotronic from the pump, both
hydraulically and electrically Try starting the
pump alone after connecting it to the mains If the
pump operates properly, inspect the Hydrotronic
from outlet hole (1), checking if the inner
impeller rotates freely If friction is encountered
Wash the Hydrotronic by filling it with vinegar or
other anti-scale product through outlet (1) It the
impeller turns freely contact the after-sales
service team
