MAINTENANCE
Periodic maintenance is essential for keeping the fan coil
efficient and must be carried out at least once a year by the
After-Sales Service Centre or qualified personnel.
Before carrying out any maintenance, disconnect from
the power supply by putting the installation on/off switch
to "off".
It may be necessary during maintenance to remove the
housing cabinets from the units; in this case proceed as fol-
lows:
- Open the motor-operated flap
- Remove all screws present and loosen the fixing screws
- Remove the housing.
Cleaning the air filters is essential for optimum operation of
the fan coil. To remove the filters:
- Switch off the appliance using the remote control.
- Put the installation on/off switch to "off".
- Raise the front grille.
- Take out the air filters.
- Remove the dust with a vacuum cleaner.
- Replace the filters, proceeding in the reverse order.
If the filters are very dusty, wash with lukewarm water
(max 40°C) and a neutral detergent; rinse thoroughly
and leave to dry in the shade.
Clean the air filters once every 2 weeks, keeping them
sealed until they are to be used, as shown in the figure.
The appliance must not be used without the air filter.
Before carrying out any cleaning, first disconnect the
appliance from the mains electricity supply by putting the
installation on/off switch to "off".
