clean the remote controller.
• Do not use glass cleaners or chemical cloths.

Eliminate the excess of water form the cloth before wiping.
Leave the unit clean from any detergent.
10.3 Cleaning the air lters
The air lter traps the dust circulated from the room into the
indoor unit.
If the lter becomes blocked, the air conditioner's efciency will
be reduced, the compressor could be damaged and the indoor
unit's heat exchanger coil could freeze up.
Clean the air lter regularly to prevent this from happening. In
order to do so:
• Remove the air lters by slightly pushing up the center tab
until it is released from the stopper and remove the lter
downwards.
• Clean the lter removing the dust or the dirt using a vacuum
cleaner or cleaning them with cold water.
• Ensure that the lters are dried completely (dry in the shade)
before putting them back into the unit. The activated carbon
lters (where tted) can be reactivated by placing in direct
sunlight. If strange odours are still smelt replace with new. If
strong odours continue to be a problem, contact your after
sales service provider to fully clean the unit.
• Attach the lter correctly and make sure it is completely xed
behind the stopper. If the right and left lters are not properly
xed, this could cause a malfunction.
b
WARNING:
Danger of breakdowns or malfunction.
Do not attach perfume systems, anti-odour systems
etc. in the lter or in the inside air return.
This can damage and soil the heat exchanger coil. If
necessary, install these systems at the unit's outlet
point and ensure they only run when the fan is on.

when the unit is located in a dusty environment.
