MAINTENANCE AND TROUBLESHOOTING

DANGER - ELECTRIC SHOCK RISK
Make sure the machine is disconnected from electric power supply, before performing servicing operation.
Under normal conditions SSCX 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. 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. 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.
PROBLEM
THE ELECTROPUMP DOES NOT PUMP WATER,
THE MOTOR DOES NOT RUN
THE MOTOR RUNS BUT THE ELECTROPUMP
DOES NOT PUMP LIQUID
