13.2 Unlocking procedure
A red light in the LED indicates a locking.
Turn the selector to the position max, disconnect and connect power supply to start the automatic
release process.
The circulator operates 100 attempts to restart (process lasts approximately 15 minutes).
Every restart is signalled by a short flash of LED light. If the locking is not removed through the
automatic release process after 100 attempts to restart the circulator, it goes into standby and the
LED remains red. In this case follow the manual procedure described in the next steps:
during any attempt, the red LED light keeps blinking; after that the circulator tries again to start. If
the locking is not removed through the automatic release process (the warning light returns to be
red), it is necessary to perform the manual proceeding described in the next steps:
Disconnect power supply - the warning light switches off.
Close the interception organs upstream and downstream of the circulator and let it cool.
Disassemble the motor and clean the impeller.
1. Disconnect power supply - the warning light switches off.
2. Close both isolating valves and allow cooling. If there are no shut-off devices, drain the
system so that the fluid level is beneath that of the circulator.
3. Carefully pull the rotor/impeller
4. Remove impurities and deposits with appropriate agents.
5. Reinsert the rotor/impeller
6. Set the selector on the wished position.
7. Connect power supply.
