4. Open the ball valve with a screwdriver (Figure 8.2.2) and
initially drain off any residual water which may be in the
device.
5. Connect the flushing set to a water tap (3/4").
6. Utilise the hose from the flushing set to flush out the pressure
vessel in a circular motion.
This process must be continued until no more lime deposits
are purged from the pressure vessel.
The water is thereby able to quickly flow out of the pressure
vessel *.
7. Close the ball valve (Figure 8.2.3).
8. Remove the maintenance hose (Figure 8.2.1).
9. For devices that are operated in combination with a pump for
deionised water: Fill 1 levelled-off teaspoon of salt into the
pressure container after flushing (Chapter 6.2).
* If water does not flow out despite the ball valve being opened
then this normally indicates that there are lime scale blockages:
Remove the maintenance hose and free up the opening in the ball
valve with a thin object. Or flush out the ball valve with the flushing
set. Insert the flushing hose in the hose sleeving or directly in the
ball valve.
