Ensure that the area is well-ventilated when the unit is operated together with a combustion appliance.• Inadequateventilationmaycauseoxygenstarvation.Turn the breaker OFF when you hear thunder and there is a pos-sibility of a lightning strike.• Theunitmaybedamagediflightningstrikes.

WARNINGConsult your dealer for installing the air conditioner. • Itshouldnotbeinstalledbytheusersinceinstallationrequiresspecialized

knowledgeandskills.Animproperlyinstalledairconditionermaycausewater leakage, fire, or electric shock.

Provide a dedicated power supply for the air conditioner.• A non-dedicated power supply may cause overheating or fire.

Do not install the unit where flammable gas could leak.• Ifgasleaksandaccumulatesaroundtheoutdoorunit,itmaycausean

explosion.

Earth the unit correctly.• Donotconnecttheearthwiretoagaspipe,waterpipe,lightningrod,or

CAUTIONInstall an earth leakage breaker depending on the installation location of the air conditioner (such as highly humid areas).• If an earth leakage breaker is not installed, it may cause electric

shock.

For installation

IMPORTANTDirty filters cause condensation in the air conditioner which will contribute to the growth of fungi such as mold. It is therefore recommended to clean air filters every 2 weeks.
