9. TROUBLESHOOTING
•
For the problems that cannot be solve with the help of these instructions, please contact the supplier or the
manufacturer.
TROUBLESHOOTING CHART
FAULT
POSSIBLE REASON
SOLUTION
Pump fails to run.
1) Main power supply is switched
off.
2) Pump overload tripped.
3) Motor winding damage or loss of
a phase.
4) Level measuring input fault.
1) Switch power supply on. Check
the ‘Power on’ LED indicator as
it should light up.
2) Check pump overloads trip
current. Adjust trip current
potentiometers to meet the
pump load specifications.
3) Consult manufacturer or
supplier.
4) Consult the
manufacturer’s
dedicated instructions for the
measuring devices (Magnetic
switches or conductive type
probes).
Low capacity.
1) Suction valve partially closed.
2) Delivery valve partially closed.
3) Incorrect direction of rotation.
1) Open valve fully.
2) Adjust valve by the required
amount to prevent cavitation.
3) Check electrical wiring
connections. Consult the pump
manufacturer dedicated wiring
instructions.
Cavitation.
1) Excessive condensate
temperature.
2) Insufficient pump discharge
head.
1.1) Check if the condensate
temperature at the pump inlet
port is higher than the one
specified.
1.2) Check and if necessary execute
maintenance on faulty (leaking)
steam traps.
2) Adjust delivery manual
regulating valve to achieve
correct duty point on the H-Q
pump characteristic curve.
10. DISPOSAL
Once the unit has reached the end of their working life, it should be sent for disposal in accordance with the prevailing
national and local regulations.
During its disposal, pay special attention to the rubbers, resins and polymers used in its construction (PVC, PTFE, PP,
PVDF, viton, etc.).
