Compared to air, water reduces the temperature

fore being given off from the air exhaust hose in
the form of vapour.
Rememberthat:
• You mustalways usesalt-free cleanwater,
tap water is recommended.
• Thelengthoftimethewaterinthetanklasts
depends greatly on environmental conditions
such as temperature, humidity, insulation,
the sun exposure of the room, the number
of people present, etc. As an estimate, the
water lasts about six hours.

• When the water in the tank runs out, the
light comes on and operation of the
appliance switches automatically to air-air.
The appliance is fitted with a resin lime-
scale filter enabling normal tap water to be
used.
The resins reduce water hardness and therefo-
re prolong the working life of the appliance.
“CF” is displayed when the limescale fil-
ter needs replacing. The efficacy of the filter
depends on water hardness. It should, howe-
ver, be replaced every five years.
Setting water hardness
Measurewaterhardnessusingtheindicatorpa-
per provided.
• Remove the indicator paper from its pack
(R).
• Immerse the paper completely in a glass of
water for one second.
• Remove the paper from the water and sha-
ke lightly. After about a minute, 1, 2,3, 4
or 5 red squares appear, depending on the
hardnessofthewater.Theappliancecanbe
set to three different water hardness levels
soft(H1),medium(H2)andhard(H3).De-
termine the hardness of the water you will be
using by comparing the red squares on the
indicator paper with the table below.
Tosetwaterhardness,proceedasfollows:
1. Set the appliance to stand-by.
2. Hold the FAN button on the control panel
downfor10seconds.Theapplianceemitsa
beep and H1, H2 or H3 is displayed.
3. Usethe +or -buttons toset thehardness
level according to the table below. Wait a few
secondsforthesettingtobememorized.The
appliance emits another beep and goes back
to stand-by.
The machine is set by default for medium
hardness (H2).
