Periodic Servicing (IMPORTANT)
This appliance should be de-scaled whenever the calcium deposit becomes
excessive (on average after 400 operating hours) or in any event at least once
every season.
INSTRUCTIONS FOR DE-SCALING
You will need: 1/4 liter de-scaling fluid
(supplied with appliance)
1 liter clean water
= 80% dilution
a) Remove the container from the unit and drain away any water left in the collecting
tray with the drainage tube.
b) Seal the drainage tube. Pour 1/4 liter of de-scaling fluid and 1 l clean water into
the collecting tray situated under the container, at the bottom of the unit.
c) Leave the air-conditioner to operate for about half an hour.
d) Drain away all the fluid left in the tray and rinse thoroughly. The drainage tube
should be open and the appliance switched on during draining.
e) Disconnect the plug from the mains and clean the collecting tray thoroughly with
a clean cloth.
f) Once the tray is clean, the appliance can resume normal operation.
IF, WHEN RESTARTING THE APPLIANCE AFTER CLEANING, TRACES OF FOAM
ARE FOUND IN THE WATER, THIS IS NORMAL. IF HOWEVER A LARGE QUANTITY
OF FOAM IS NOTED, RINSE THE APPLIANCE ONCE AGAIN.
FURTHER SUPPLIES OF DE-SCALING FLUID CAN BE OBTAINED FROM YOUR
LOCAL DE LONGHI SERVICE CENTRE.
