MAINTENANCE AND TROUBLESHOOTING
DANGER - ELECTRIC SHOCK RISK
Make sure the machine is disconnected from electric power supply, before performing mainte-
nance operation.
In ordinary conditions, GARDEN PUMPS PENTAIR FLOTEC do not require any maintenance To prevent possible
problems, it is advisable to periodically check the pressure supplied and current absorption. A reduction of the
pressure may indicate that the electropump is worn. Sand and other corrosive materials present in the delivery fluid
cause a rapid wear and a reduction of performance. In this case, it is advisable to use a filter. An increase in current
absorption indicates the presence of abnormal mechanical friction in the pump and/or the motor.
If the electropump is not going to be used for a long period of time (i.e. one year), it is advisable to empty it comple-
tely (by opening the drain cap, see Fig. 1 n. 10), rinse it with clean water and store it in a dry location, where it can be
protected from frost.
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 PERIOD
OF TIME BECAUSE ONE OF
THE THERMAL MOTOR CIRCUIT
BREAKER TRIPS
If the problem persists despite the recommended corrective actions, contact the Customer Assistance Service.
12
POSSIBLE CAUSE
1) No power.
2) Motor protection tripped.
3) Defective condenser.
4) Shaft blocked.
1) The pump is sucking air.
1) The power supply does not
comply with the data on the
nameplate.
2) A solid object is blocking the
impeller
REMEDY
1) Verify that voltage is present and that the plug has been correct-
ly inserted.
2) Determine the cause of the problem and reset the switch. If the
thermal switch has been enabled, wait for the system to cool down.
3) Contact the Customer Assistance Service.
4) Verify the cause and unblock the electropump.
1) Verify that the joints are sealed.Verify that the fluid level has not
lowered below the foot valve.Verify that the foot valve is sealed and
not blocked.
1) Check the voltage on the power supply cable leads.
2) Contact the Customer Assistance Service
