MAINTENANCE

For safety reasons, before carrying out any maintenance or
cleaning jobs, turn off the unit by moving the fan speed se-
lector to "OFF" and putting off the main switch 0 (OFF).
Any work must be carried out by personnel qualifi ed and au-
thorised to work on this type of unit.
A DANGER!
Due caution must be taken while carrying out
maintenance: some metal parts may cause injuries; wear
protective gloves.
The material must undergo maintenance in order to retain its
characteristics over time. Lack of maintenance may have the ef-
fect of voiding the product warranty. The operations consist of
cleaning the air fi lter, the internal and external exchangers, the
cabinet, and cleaning and protecting the condensate drip trays.
Odour treatment and disinfection of the surfaces and spaces al-
so contribute to the healthiness of the air breathed by users.
Whenever starting up the unit after it has not been used for a
long time, check that there is no air in the heat exchanger.
Before the period of operation in the cooling mode, check that
condensate is properly drained.
Adequate periodic maintenance will ensure save both ener-
gy and cost savings.

4. Open the grille (3) downwards.
5. Remove the fi lter (4) from the grille.
6. Use a vacuum cleaner to remove dust. If dust is glued to the
fi lter, remove it with clean or soapy water, rinse the fi lter with
clean water and dry it.
7. Put the fi lter back into its place in the grille, close the grille,
moving the two retainers outwards, then put the screws se-
curing the retainers back in place.
It is recommended to replace the air fi lter once a year, using an
original replacement fi lter; the indoor unit model can be found
on the identifi cation plate located on the tank inside the unit,
behind the air fi lter.
