PREPARING FOR
WATER MODE
Once the appliance has been installed, it is ready
for use.
However, its efficiency can be enhanced by ope-
rating it in the exclusive De'Longhi water mode.
The water in the tank increases the cooling po-
wer of your Pinguino and at the same time redu-
ces noise levels and electrical consumption.
Compared to air, water reduces the temperature
of the cooling circuit much more efficiently, be-
fore being given off from the air exhaust hose in
the form of vapour.
Remember that:
• You must always use salt-free clean mains
water.
• The length of time the water in the tank lasts
depends greatly on environmental condi-
tions such as temperature, humidity, insula-
tion, the exposure of the room, the number
of people present, etc.
Indicatively it lasts about six hours.
The BOOST function (see page 30) shortens
the operating time to about 4 hours, but the
cooling power and efficiency are increased.
• 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 impregnated resins reduce water hardness
and therefore prolong the working life of the
appliance.

depends on water hardness.
Setting water hardness
Measure water hardness using the indicator pa-
per provided.
• Remove the indicator paper from its pack (V).
OPERATION IN
• 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
hardness of the water. The appliance can be
set to three different water hardness levels
soft (H1), medium (H2) and hard (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.
Kind of water used
19 soft
Medium
20
Hard
To set water hardness, proceed as follows:
1. Set the appliance to stand-by.
2. Hold the FAN button on the control panel
down for 10 seconds. The appliance emits a
H1, H2
beep and
3. Use the + or - buttons to set the hardness
level according to the table above. Wait a few
seconds for the setting to be memorized. The
appliance emits another beep and goes back
to stand-by.
The appliance is set by default for medium
hardness (H2).
Filling the tank
The water tank is located at the bottom of the
appliance. Extract the tank by inserting the hand
through the door above the word "PULL" (fig.
13) and pulling the tank out as far as it will go.
Remove the cap and use a container (bottle, jug,
watering can) to pour in the water (fig. 14/15).
