WARNING!
Electric shock may result.
● Make sure the plasma filter unit is properly mounted before cleaning or performing other tasks
CAUTION!

Regarding the Air Cleaning check function
● This function is illustrated by the flashing of the AIR CLEAN Indicator Lamp (green) (Fig. 3 7), indicating that the unit
requires maintenance.
After Air Cleaning Mode has been in use for approximately 400 hours, the AIR CLEAN Indicator Lamp (green) (Fig. 3 7)
will begin to slowly flash (approximately once every 7 seconds). When this occurs, the unit requires maintenance.
After Air Cleaning Mode has been in use for approximately 500 hours, the AIR CLEAN Indicator Lamp (green) will begin to
flash quickly (approximately once every 3 seconds). At this point, Air Cleaning will cease functioning. Please carry out
appropriate maintenance for the unit.
● Please carry out unit maintenance every 6 months.
● If a squeaking or chirping sound is heard, unit maintenance needs to be carried out, even if the AIR CLEAN Indicator Lamp
(green) (Fig. 3 7) is not flashing.

1 Soak the plasma filter unit in warm water (40 to 45˚C)
for 10 to 15 minutes. If the plasma filter unit is ex-
tremely dirty, extremely dilute a mild synthetic laun-

to dry completely.
● Only use a mild synthetic laundry detergent (low
alkalinity or isotope detergent).
● Never disassemble the plasma filter unit.
● Never soak the plasma filter unit in hot water.
● Never wipe the plasma filter unit with a scrub brush
or other hard or abrasive items. This will damage
the honey comb filter.

unit for washing. This will damage the internal parts
and cause malfunctioning of the plasma filter unit.
● Never use dryer or other device to blow hot air on
the plasma filter unit. This will cause deformation
