Question: Why is the circulator pump making noise, and what can be done about it?


Possible cause of fault

Air in the pump


The pump is self-venting.

Note the pump's control setting on the display.

In order to vent the pump rapidly, set the pump to maximum speed and let it run for half an hour. Then return it to the original control setting.

If this does not solve the problem, please call your professional installer.

Possible cause of fault

Inlet pressure too low


These faults can only be remedied by a specialist company.

Call your professional installer.
