MAINTENANCE AND TROUBLESHOOTING

DANGER - ELECTRIC SHOCK RISK
Make sure the machine is disconnected from electric power supply, before performing servicing operation.
DANGER - ELECTRIC SHOCK RISK
The power cord must be replaced by the manufacturer or the Customer service, using special tools.
• Under normal conditions DOMINATOR
electropumps do not need any type of
maintenance. In order to avoid possible
failures, it is advisable to periodically
check the pressure supplied and
current absorption.
CLEANING THE FILTER
• If the sucked water is not perfectly
clean, it may be necessary to clean
the filter with a steel brush to scrape
the dirt accumulated on the external
surface.
PROBLEM
THE ELECTROPUMP DOES NOT PUMP
WATER, THE MOTOR DOES NOT RUN
THE MOTOR RUNS BUT THE ELECTROPUMP
DOES NOT PUMP LIQUID
THE ELECTROPUMP STOPS AFTER RUNNING
FOR A SHORT PERIOD OF TIME BECAUSE
ONE OF THE THERMAL MOTOR CIRCUIT
BREAKER TRIPS
If the problem cannot be eliminated after carrying out the above-described operations contact the closest service centre.
8
• A decrease in pressure is a symptom
of wear. An increase in current
absorption is a sign of abnormal
mechanical friction in the pump
and/or motor.
• It is also possible to clean the internal
section of the filter.
• Loosen the screw that fixes the filter
to the body of the electropump and
remove it.
POSSIBLE CAUSE
1) No power.
2) Motor protection tripped.
3) Defective condenser.
4) Shaft blocked.
1) The pump is sucking air.
2) The pump rotates in the wrong direction
3) Suction grid blocked.
4) Check valve blocked.
1) The power supply does not conform with
the data on the nameplate.
2) A solid object is blocking the impellers.
3) The liquid is too thick.
• If the electropump is not going to be
used for long periods of time it should
be emptied completely, rinsed with
clean water and put in a dry place.
• Scrape the dirt with a steel brush and
rinse it with clean water.
• If this is not sufficient, have the
hydraulic parts cleaned by an
authorised centre.
REMEDY
1) Check the presence of voltage and if the plug is plugged in properly.
2) Verify the cause and reset the switch. If the thermal circuit breaker
has tripped wait for the system to cool down.
3) Replace the condenser.
4) Verify the cause and unblock the electropump.
•
Make sure that the joints are airtight.
•
Check that the level of liquid has not dropped below the minimum
priming level.
2) Reset the direction of rotation.
3) Clean the suction grid.
4) Clean or replace valve.
1) Check the voltage on the power supply cable leads.
2) Take the electropump to an authorised centre so that it can be
disassembled and completely cleaned.
3) Change the type of electropump.
