Evacuation of condensate water in the event of an emergency
Should any anomaly occur in the condensation water system,
the maximum level float blocks the conditioner and the
OF
code appears on the display.
During cooling and dehumidification, electronics keeps the
water distribution system active with the battery - together
with the fan - to disperse excess water in the container. If the
problem persists, please contact the assistance service.
During heating, condensation should drain freely through
the specific pipe. In the event of an alarm, check that the
condensation pipe is not bent or obstructed, thus preventing
the water from flowing out.
Use of the appliance
Objects or structural obstacles (furniture, curtains, plants,
leaves, blinds, etc.) must not obstruct the normal air flow
both from the internal and from the external grids.
Do not lean against, or worse sit on, the body of the
conditioner, this would damage the appliance.
Do not move the horizontal air outlet flap manually.
Always use the remote control to perform such operation.
In the event of water leaks, turn off the appliance and
disconnect the electric power supply. Call the nearest
service centre.
During heating mode, the conditioner eliminates
periodically any ice formed on the external battery. In such
situation, the machine keeps on working, but it does not
dispense warm air to the room. This phase can last from 3
up to maximum 10 minutes.
The appliance must not be installed in rooms where
explosive gases develop or where there are humidity and
temperature conditions that exceed the maximum levels
reported on the installation manual.
Clean the air filter regularly as described in the specific
paragraph.
