A	B	•	Always turn off the power, first on the remote controller and then
			the main switch, before cleaning or servicing the unit.
		•	When installing or removing the filter or the intake grille, do not
			stand on an unsteady surface. You may fall and injure yourself. Be

also careful not to let dust fall into your eyes.

Dirty or clogged filters block the airflow and reduce efficiency. Very dirty filters can damage the air-conditioner itself.

3.1. Cleaning the filters and the indoor unit Cleaning the filter

• Clean the filter using a vacuum cleaner. If you do not have a vacuum

cleaner, tap the filter against a solid object to knock off dirt and dust.

• If the filter is especially dirty, wash it in lukewarm water. Take care to rinse off any detergent thoroughly and allow the filter to dry completely before putting it back into the unit.

Caution:

• Do not dry the filter in direct sunlight or by using a heat source, such as an electric heater: this may warp it.

• Do not wash the filter in hot water (above 50°C), as this may warp them.

• Make sure that the air filter is always installed. Operating the unit without air filter can cause malfunction.

Cleaning the indoor unit

• Wipe the outside of the unit with a clean, dry, soft cloth.

• Clean off any oil stains or finger marks using a neutral household deter- gent (such as dishwashing liquid or laundry detergent).

Caution:

Never use gasoline, benzene, thinner, scouring powder or any type of non-neutral detergent, as these substances may damage the unit’s case.
