8.14 - Removing the diverter valve 

servomotor

When not otherwise specified, refer to Figure 68.

1. - Remove the air manifold "C" (Figure 40) making sure to 

rotate it outwards and then slide it out of the fan inlet;

2. - Extract drive bar “A” towards the front;

3. - Extract servomotor “B” upwards;

8.15 - Removing the diverter valve

When not otherwise specified, refer to Figure 69.

1. - Remove the diverter valve servomotor (section 8.14);

2. - Empty the central heating circuit (section 8.19);

3. - Remove to the front the drive bar “D”;

4. - Slide diverter valve “E” upwards;

5. - To reassemble the mixing valve correctly, it is necessary 

to match detail "G" in seat "H";

8.16 - Removing the flow meter

When not otherwise specified, refer to Figure 70.

1. - Empty the domestic hot water circuit (section 8.20);

2. - Extract drive bar “A” towards the front;

3. - Extract flow meter “B” upwards;

4. - Extract filter "C" from the flow meter "B";

5. - Clean filter “C”;

6. - Fit the filter "C" on the flow meter "B";

7. - Refit the flow meter "B", the two tabs must be slotted 

into the respective holes in the hydraulic unit (the 

largest towards the front of the appliance and the 

small one at the rear);
