11.3.2 Replacing the electronic unit

1. See section 

11.3.1 Opening the electronic unit

2. Remove the wires of the dry-running sensor, Pt1000 sensor 

and capacitor (single-phase pumps) as well as the earth lead.

3. Cut the motor leads between the electronic unit and the stator 

housing in the middle.

4. Remove the level sensor (see sectio

11.5.2 Replacing the 

level sensor

) and the cable plug (see section 

11.6 Replacing 

the cable plug

) from the old electronic unit and fit them in the 

new one.

5. Remove approximately 60 mm of the insulating sheath of the 

cable from the new electronic unit so that approximately 75 
mm of the three leads are stripped.

6. Cut away 5, 30 and 55 mm of the three leads from the 

electronic unit and from the stator housing so that the joints 
are displaced from each other. See fig. 

19

. For instance, if 5 

mm of the red lead from the electronic unit are cut away, 55 
mm of the red lead from the stator housing must be cut away.

Leads with connectors

7. Strip the three leads from the electronic unit and from the 

stator housing using a cable stripper.

8. Pull a new 16 mm insulation sheath over the original 

insulating sheath of the motor leads. See fig.

9. Pinch connectors on the three leads with a crimping tool.

10. Grab the leads on each side of the connector and pull a little 

to check the joints.

11. Carefully pull the new insulating sheath over the joints and fix 

it with a cable clip.

12. Connect the wires from the dry-running sensor, Pt1000 sensor 

and capacitor (single-phase pumps) as well as the earth lead.

13. Fit the electronic unit. See section

stator housing and the electronic unit.

2. Fit the O-ring in the stator housing.
3. Place the wires in the hollow space and fit the electronic unit 

on the stator housing.

4. Fit the four screws (188a). See section 

8. Torques and 

lubricants

.

11.4 Replacing the run capacitor, single-phase pumps

11.4.1 Dismantling the run capacitor

1. Open the electronic unit. See section

electronic unit

.

2. Disconnect the capacitor wire from the electronic unit.
3. Remove the Pt1000 plug from the PC board.
4. Remove the earth lead from bracket (161c).
5. Remove the capacitor bracket with capacitor from the stator 

housing.

11.4.2 Assembling the run capacitor

1. Fix the capacitor wire on the PC board.
2. Fit the earth lead on the new bracket.
3. Fit the new Pt1000 sensor.
4. Fit the electronic unit. See section 

11.3.3 Closing the 

electronic unit

.

11.5 Replacing the sensors

11.5.1 Replacing the dry-running sensor

Observe the bar code on the sensor wire, for example 96892923-
01-039-01192. In case the bar code contains the figure 01, 
replace the sensor with a new one, version 02.

Dismantling the dry-running sensor

1. Open the electronic unit. See section 

11.3.1 Opening the 

electronic unit

.

2. Remove the sensor wire from the PC board.
3. Remove the set screw (285b).
4. Press the sensor out of the stator housing with a screwdriver 

(

E

). Do not reuse the sensor.

5. Clean the sensor hole.

Assembling the dry-running sensor

1. Lubricate and fit the O-rings (285a).
2. Lubricate the sensor hole.
3. Press the sensor home in the stator housing.
4. Connect the sensor wire to the PC board.
5. Fit a new set screw. See section 

8. Torques and lubricants

.

6. Fit the electronic unit. See section 

11.3.3 Closing the 

electronic unit

The leads must be connected in such a way that the 
colours from the electronic unit and the stator 
housing match.

Make sure that the wires are not pinched between 
the stator housing and electronic unit.
