10.1 Dismantling the product
1. Switch off the power supply.
2. Pull out the superseal power cable.
3. Close the two isolating valves on both sides of the pump.
4. Loosen the fittings.
5. Remove the pump from the system.
10.2 Deblocking the shaft
If the pump is blocked, it is necessary to deblock the shaft. The
pump deblocking device is accessible from the front of the pump
without having to demount the control box. The force of the device
is high enough to deblock pumps, which are seized by lime, for
example if the pump has been turned off during summer.
Course of action:
1.
Switch off the power supply.
2. Close the valves.
3. Locate the deblocking screw in the centre of the control box.
Use a star screwdriver with a size 2 Phillips tip to push the
deblocking screw inwards.
4. When the screw can be turned counterclockwise, the shaft has
been deblocked. Repeat step 3, if necessary.
5. Switch on the power supply.
