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, PENTAIR FLOTEC AUTOJET series electropumps 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 cur-
rent 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.

Contact customer services if the problem persits
1) Check to ensure that joints are leak proof.
- check that liquid levels have not decreased beneath the foot valve.
- Check to ensure that the foot valve is unblocked and leak proof.
1) Check the voltage on the power supply cable leads.
2) Contact customer services.
