DESCALING
When using the appliance in water mode, lime scale will inevi-
tably form and must be removed to maintain efficiency. After
about 500 hours of operation, the appliance therefore warns that
descaling is required by displaying the message CL (CLEAN).
Descale the appliance.
• Turn off the appliance and unplug from the socket. Empty all
water from the inside of the appliance through the drain
hoses (fig. 35).
• Close and replace the drain hoses. Pour 0.5 Liters of descaler
(one bottle) and 1.5 Liters of clean water into the tank.
• Plug in and operate the appliance in air conditioning mode
with the BOOST function selected until the "no water"
symbol appears on the display.
• Turn off the appliance and unplug from the socket. Empty all
water from the inside of the appliance through the drain
hoses.
• Close and replace the drain hoses. Pour 2 Liters of clean
water into the tank to rinse the internal circuits of dirt and
descaler.
• Plug in and operate the appliance until the "no water"
symbol appears on the display.
• Turn off the appliance and unplug from the socket. Empty all
rinsing water from the inside of the appliance through the
drain hoses.
• If the water drained off is very dirty or contains large quanti-
ties of foam, repeat the rinsing operation.
• Close the drain hoses and replace.
• After descaling, reset the alarm by pressing the button for
10 seconds.
The descaler can be
bought from your local
De'Longhi service center.
Always use original
descaler. Use of other pro-
ducts could damage
internal components and
invalidate the guarantee.
