Unblocking Procedure:

A red light in the LED indicates the circulator rotor is blocked or sticking. Turn the selector to the position MAX, disconnect

and connect power supply to start the automatic release process. The circulator makes 100 attempts to restart (process lasts

approximately 15 minutes). Every restart is signalled by a short ash of white LED light. If the blocking is not removed through

the automatic release process after 100 attempts to restart, the circulator goes into standby and the LED remains solid red.

Perform the manual unblocking steps described below.

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 uid level is

beneath that of the circulator.

3. Loosen 4 motor bolts. Remove motor from casing. Carefully pull the rotor/impeller from the motor.

4. Remove impurities and deposits from the impeller and casing.

5. Reinsert the rotor/impeller into the motor.

6. Set the dial to the MAX position.

7. Connect power supply. Check for impeller rotation.

8. If the circulator still doesn’t run it will need to be replaced.
