ROUTINE MAINTENANCE
Cleaning the exterior, interior, and accessories
Use a dry cloth to wipe down the outside and inside of the unit and all accessories. If the outside panels
are dirty, clean them with a diluted neutral dish-washing detergent.
Wipe off condensation from the exterior of the cabinet with a dry, soft cloth.
Using an undiluted solution of detergent may cause the unit's plastic areas to crack. Follow the
directions on the detergent for details of dilution.
After the wiping the cabinet or accessories with a diluted detergent, be absolutely sure to wipe the
surfaces with a cloth dipped in clean water to remove traces of the detergent. After this, be absolutely
sure to wipe the surfaces with a dry cloth.
<Important>
■ Do not use a brush, an acid, a thinner, laundry soap, a powder detergent, or boiling water for cleaning.
These may cause damage to painted surfaces or cause perishing of plastic and rubber components.
Moreover, do not wipe plastic and rubber components with a volatile material.
■ In order to maintain the unit's intended level of performance, always replace accessories that have
been removed for cleaning.
Cleaning the filter
Clean the filter when the filter check indicator lights up and the buzzer sounds. Clean the filter once a
month even if the filter check indicator is not lit since a clogged filter may reduce life of the compressor as
well as causing reduced cooling performance.
Clean the filter by the procedure below.
1. Mute the buzzer by pressing the buzzer stop key (BUZZER) when the buzzer sounds.
2. Open the grille by pulling it toward you, as shown in the
figure.
3. Take out the filter.
4. Wash the filter with water.
5. Replace the filter and the grille. (The handle of the filter
should be on the top.)
6. If the filter check indicator was previously on, check that
this indicator is now off.
