The descaling procedure is as follows:
1. If the system is switched OFF and the
water is cold, drain off as much water as
possible via the hot water tap.
2. If the system is switched ON it must be
switched off and as much hot water as
possible drained. Cool the system by
pouring 3 litres of cold water into the
reservoir and draining it off again.
3. Dissolve 100 gr. descaling agent in ± 0.5
litre lukewarm water.
4. Pour the solution carefully into the hot
water reservoir.
5. Switch on the appliance again.
6. When the reservoir has been filled up to
the next to the highest electrode, wait ten
minutes.
7. Meanwhile, draw off a cup of descaling
solution every minute from the usual hot
water tap (thereby giving the tap a good
descaling as well.)
8. Switch off the appliance once the ten
minutes is up and draw off as much
solution as possible via the usual tap.
9. Then pour ± 3 litres cold water into the
reservoir (to cool the system quickly).
10. To drain the reservoir quickly, the entire
appliance can be carefully tilted.
11. Now pour ± 5 litres of water into the
reservoir. Make sure it doesn't overflow.
12. Drain as much water as possible via the
usual hot water tap and dispose of it.
13. Then drain the reservoir entirely
according to instructions 10.
14. Dispose of the water and repeat
operations 11 and 12 at least twice, but
now with ca. 4 litre water.
15. Switch on the water boiler.
16. Before using the hot water for
consumption, it is advisable to rinse the
tap well once more by first drawing off
another litre or so of hot water via the hot
water tap.
Important:
If you do not use the step 10 to empty the
entire reservoir, the 4 litre rinsing procedure
has to be repeated more often before the
machine is switched on for normal use again.
See the last 3 instructions for the descaling
process.
CAUTION !
- Leave the reservoir uncovered during the
entire descaling process.
- Prevent the descaling agent from touching
the top electrode.
- Due to the violent reaction which occurs
when the descaling agent comes into
contact with the calcium deposits, the water
may touch the topmost (safety) electrode,
thus switching off the system. In that case,
switch the system off manually using switch
2 (fig. 1). Wait ca. 20 seconds and switch
the system on again in order to continue
the descaling process.
