utes of the procedure the product is still not primed, the interface display
sends a failure message. Disconnect the power supply, load the product
adding new water, wait 10 minutes and repeat the procedure from the
moment you put the plug in the socket.
Press "-" to confirm that you do not want to start the priming procedure.
The product remains in alarm status
Operation
Once the electropump is primed, the system starts regular operation ac-
cording to the configured parameters: it starts automatically when the tap
is turned on, supplies water at the set pressure (SP), keeps the pressure
constant even when other taps are turned on, stops automatically after
time T2 once the switching off conditions are reached (T2 can be set by
the user, factory value 10 sec).
4 - PROTECTION SYSTEMS
IThe device is equipped with protection systems to preserve the pump,
the motor, the supply line and the inverter. If one or more protections trip,
the one with the highest priority is immediately notified on the display.
Depending on the type of error the motor may stop, but when normal
conditions are restored the error status may be cancelled immediately or
only after a certain time, following an automatic reset.
In the case of blockage due to water lack (BL), blockage due to motor
overload (OC), blockage due to direct short circuit between the motor
phases (SC), you can try to exit the error conditions manually by simul-
taneously pressing and releasing the + and – keys. If the error condition
remains, you must take steps to eliminate the cause of the fault.
In the event of blocking due to one of the internal errors E18, E19, E20,
E21 it is necessary to wait 15 minutes with the machine powered until the
blocked status is automatically reset.
