4. END OF SEASON MAINTENANCE

WARNING:
- Unplug the appliance or switch off the dedicated switch before performing any operations (risk of personal injury
from electrocution).
- Do not touch the air conditioning unit with wet hands (risk of personal injury from electrocution).
- When cleaning the appliance, do not climb onto a table or unstable chair (risk of personal injury due to falling
from a height).
- When removing filters, take care not to touch any metal parts, especially the heat exchanger inside the internal
unit (risk of personal injury from cuts).
1. Clean the filters and secure them back in place.
2. On a sunny day, run the air conditioning unit in ventilation mode for a few hours, so that the inside is completely dry.
3. Unplug the appliance or disable the automatic switch.

4.1 If the air conditioning unit does not work

1. If the appliance shows no signs of life, make sure that:
- power is being supplied from the mains
- the automatic switch has not blown
- the power supply has not been cut off
- the air conditioning unit comes on when the ON-OFF button on the internal unit is pressed
2. If the cooling (or heating) effect seems to be lower than normal:
- has the temperature been set correctly on the remote control?
- has a door or window been opened?
- is the Internal Unit exposed to direct sunlight?
- are the filters clogged?
- are there any obstacles preventing the free circulation of air to the Internal Unit or External Unit?
The performance levels and the characteristics of any cooling appliance are noticeably affected by the environmental
conditions where the Internal and External Units operate.
