CLEANING THE PLASMA DEODORIZING/AIR PURIFY-
ING FILTER UNITS
If the PLASMA/WASH lamp on the indoor unit blinks, clean the filters as soon as possible. The lamp will
start blinking when accumulated operating time exceeds 330 hours.
Before cleaning
Switch the indoor unit off with the remote controller and dis-
connect the power supply plug and/or turn off the breaker.
Otherwise, you may get injured since the PLASMA DEO-
DORIZING/AIR PURIFYING filter units are charged with high
voltage.

Cleaning
1
Vacuum the filter surface using a vacuum
cleaner or wash with water, and then soak
the filters in warm water of 30 to 40 C for 10
to 15 minutes. (To remove persistent stains,
clean the filters with a water-diluted mild or
weak alkali detergent.)
• Deodorizing ceramic filter inside the PLASMA DEO-
DORIZING filter unit is fragile, so handle it with care.
Clean the filter without removing it from the filter
unit. (See the description to the right for the details
of the deodorizing ceramic filter.)
NOTE:
• If the D.S. PLASMA unit is soaked in water to clean, the filter frames may turn white, but this does not affect performance
or quality. Continue to use the unit.
• Do not use detergents that contain bleach.
• Do not disassemble the PLASMA DEODORIZING/AIR PURIFYING filter units.
• Do not dry the PLASMA DEODORIZING/AIR PURIFYING filter units using hot air from a hair dryer, etc. (The filter unit
may deform due to heat.)
• Install the PLASMA DEODORIZING/AIR PURIFYING filter units only when they are completely dry. If the filter unit
remains wet, the PLASMA/WASH lamp may blink and the PLASMA function may be disabled.
