Troubleshooting

Corrective Action 

(continued)

Replacing the flow rate sensor
Note:

  In the event of a fault, both sensors need to be 

replaced.

1.  Drain the boiler on the heating water side.
2.  Pull leads from flow rate sensor 

A

.

3.  Undo screws and remove faulty flow rate sensor 

A

.

4.  Install new flow rate sensor 

A

 and secure with the 

screws.
