CLEANING AND MAINTENANCE

The appliance requires no periodic maintenance. Simple checks by the
user to keep it in perfect working order are, however, necessary.
CAUTION! Before carrying out any cleaning or maintenance work,
disconnect the appliance from the mains electricity supply!

ORDINARY MAINTENANCE

For standard use of the unit in normal condition we recommend:
- To clean the air fi lter every 6 month and change it every 2 years
- To clean the housing
- To clean the coil
- To clean the drain fi tting (check the normal condensate fl ow)
CLEANING THE AIR FILTER
The appliance is fi tted with an air fi lter on the fan inlet. During normal
operation the fi lter withholds impurities in the air.
The fi lter should be cleaned periodically to keep its fi ltering properties
and the airfl ow to the fan unchanged. It is advisable to clean the fi lter at
least once a month, proceeding as follows.
1. Take out the fi lter.
2. Place the fi lter on a fl at, dry surface and remove the accumulated
dust with a vacuum cleaner.
3. Wash the fi lter with water and detergent (no solvents).
4. Leave the fi lter to dry in a ventilated place in the sun.
5. Replace the fi lter when it is perfectly dry.
Clean the fi lter at the beginning and end of every season.

CLEANING THE HOUSING AND THE CONTROL PANEL

To clean the housing, use a dry soft cloth to avoid scratching the enamel.
To clean the control panel and the air outlet louvres, use a vacuum clea-
ner fi tted with a soft dusting tool or use a separate brush.
Delicately clean the louvres and the controls by removing dust from the
cracks and corners.
Under no circumstances use water.
