Ch. 7 Maintenance and troubleshooting
DANGER
Electric shock
risk
In ordinary conditions, 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 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 completely (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.
