When the scale deposits become excessive
(on average, after about 400 hours of opera-
tion) or in any case, at least once each sea-
son, it is very important to proceed with the
decalcification of the appliance as described
below.
To remove the scale from the appliance, you
need:
•
250 ml of descaling liquid
•
750 ml of clean water
(corresponding to a diluted solution of 75%)
Proceed as follows:
1) Remove the tank
from the appliance
and drain the water remaining in the col-
lection reservoir
by using the draina-
ge hose
(fig.
H
).
2) Close the drainage hose
. Pour 250 ml
of decalcifying liquid
and 1 litre of clean water into the collec-
tion reservoir
which is found under the
tank (fig.
I
), on the bottom of the applian-
ce.
3) Operate the air conditioner for about half
an hour.
4) After this, drain out all of the liquid remai-
ning in the collection reservoir and rinse
thoroughly. During the rinsing process, the
drainage hose must be open and the
appliance functioning.
5) Unplug the appliance from the mains and
clean the collection reservoir thoroughly
with a clean cloth.
6) After cleaning the collection reservoir, the
air conditioner can be used normally.
