Safety Precautions (Continued)
CAUTION
Miscellaneous
Securely hold the grip when carrying
air purifi er.
Damaging or dropping it may cause injury.
When you attach or detach the panel
and water tank, do it slowly and securely.
Otherwise, it may cause water leakage or
injury of fi ngers pinched.
Use dry cell batteries properly after
reading the precautions on them.
Renew water in the water tank daily using
tap water and clean the tank periodically
according to the instructions given in the
“Cleaning” section of this manual.
Continued use without cleaning may allow
propagation of molds or bacteria due to
dirt and water scale, producing unpleasant
odor. In rare cases, they may cause a
health risk to those who are hyperactive. In
such a case, please seek medical advice.
Only use fresh tap water
Otherwise, it may cause deformation or
degeneration of parts, unit failure or unpleasant
smell due to propagation of molds or bacteria.
Do not use hot water (over 40ºC), water
through water purifi er, alkali ion water, mineral
water, well water or the like. Do not put organic
solvent or chemicals into the water tank.
Do not drink, or let drink, water in the
water tank and water tray.
It may cause a health threat.
Do not leave the detached water tank
with its cap closed.
Inner pressure of the tank changes
according to ambient temperature change
and may cause water leakage or injury
due to deformation or damage.
Use a genuine fi lter for the Hitachi Air Purifi er.
Other fi lters may cause unit failure.
Do not operate the unit when
using fumigating (smoking) type
insecticide.
Using such insecticide will cause
chemicals to accumulate in the unit and
to be emitted by subsequent operation,
which can be harmful to heath.
After using insecticide, ventilate the
room well before running the purifi er.
Do not allow water to freeze.
Water tank may be damaged, causing
a risk of electric shock and unit
failure. Whenever freezing of water is
anticipated, drain the water tank and
water tray.
Do not use the purifi er having water
leakage trouble.
It may cause electric shock. When
water leaks, unplug the power cord
from AC outlet and ask for repair.
Do not carry the purifi er with its
water tank fi lled.
It may cause water leakage or injury.
If you carry the purifi er with fi lled water
tank, level of water in the tray will rise
and cause the water to overfl ow when
operated.
Drain the water tank and water tray
fi rst, and set them on the unit before
carrying.
Do not tip over or drop the water
tank when it is fi lled.
It may cause injury or result in deformed
or damaged tank. Hold the tank
securely when you fi ll it with water.
Do not look into the indicator.
It may cause injury to your eyes.
To Prevent Floor Scratches or Wall Stains
During Cleaning / Place of Use
During cleaning, lay a soft cloth on
the fl oor and place the purifi er and
detached components (panel, water
tank, water tray, etc.) on it.
Otherwise, it may cause scratches on
the fl oor.
When you pull out the water tray, be
careful not to scratch the fl oor with
bottom of the tray.
E-6
Do not use the air purifi er near the
wall that cannot be scrubbed such
as cloth-covered white wall.
The air purifi er will take in the
surrounding air and may produce local
stains.
Cautions on Use
Do not install in an unstable or sloped
place, or near any obstacles.
The unit may fall or drop,
resulting in damage or unit failure.
If the space between the unit and
floor remains humid, the floor
may get moldy.
Using the unit tilted may cause
water leakage.
Do not drag the unit on any floor susceptible
to scratches or on thick carpet.
It may cause damage on floor or carpet surface.
Do not run with filter detached.
No cleaning effect is
obtainable without filter.
Running without filter
may also cause unit
failure.
Do not directly fan animals and plants.
Air drafts may adversely affect them.
Do not place anything on the air purifier
body, and do not block the
air inlet or air outlet.
Acts of the sort may cause unit
failure.
Do not touch or move the unit (angle
or lift the unit) during operation.
Moving the operating unit may cause the fan to contact
the inner case, resulting in noise and possibly unit failure.
Do not place the purifier in a place exposed
to direct sunlight.
Safety Precautions Cautions on Use
Direct sunlight may
cause deformation,
discoloration or
malfunction.
Do not block or touch the infrared receiver,
odor sensor, Dust sensor or humidity sensor.
Infrared receiver may be stained
or damaged to reduce its
sensitivity.
Sensors may be degraded in
their sensitivity.
Do not install in a place where the air from the
purifier will blow directly on furniture, electric
appliance, wall or ceiling.
Humid air may cause stain
or deformation of furniture,
or may cause unit failure.
Ventilate closed room occasionally.
The air purifier does not have a ventilation
effect.
✽
The air purifier cannot
remove hazardous
substance in cigarettes
(carbon monoxide, etc.).
Do not subject remote controller to
impact.
Do not drop the remote
controller or step on it, and
do not place any object on
it. Doing so may cause unit
failure.
Do not subject water tank to impact.
Water may leak from the tank
to wet the floor. Also water
may drip from the tank cap to
wet the floor.
Do not use near television or radio.
Broadcast may be
interfered. Install the air
purifier 2m or more away
from such devices.
E-7

water tank handle, lift it obliquely
upward, and remove the water tank by
supporting it in the bottom.
Handle
Insert batteries and close the cover.
Insert the provided two “AAA” R03 batteries
with the correct polarities as instructed.
Since the batteries are provided when shipped from
the factory, their lives may be shorter than brand-new
ones because of self-discharge.
Batteries are consumable
When replacing batteries, replace the two batteries simultaneously.
Only use two manganese batteries or two alkali batteries.
Do not mix them.
Remove the tank cap and fill fresh tap
water of normal temperature.
Rubber packing
Check that the tank cap is equipped
with a rubber packing.
Loosen
Tighten
Do not push in the
pin in the cap center.
Doing so may cause
water leakage.
Preparations for Operation
Hold the water tray.
Do not carry the water tank by holding its
handle. Instead, hold the tank with both
CAUTION
hands and carry it while keeping the tank
cap side up. When the water tank is wet,
wipe off water drops before carrying.
Pull out the water tray, check
that the humidifying filter and
tray cover are equipped, and
then retract the tray.

Handle
Press the center pin of the tank cap, and check that it
comes back by spring.
Tighten the tank cap firmly, wipe off spilt water, and
check that there is no water leakage.
Wipe off water on the water tank handle if any.
The tank cap is a consumable part. P.E-28
(If it leaks water due to deteriorated rubber packing,
please purchase separately available part for
replacement.)
Set the water tank into the water tank
holder.
Be sure to handle the water-filled tank with both hands.
Press in the tank securely until it clicks. Inadequate
setting may cause the water tank to fall or result in water
leakage.
Pin
Tray cover
Water tray
Slowly pull out the water tray while lifting it
obliquely upward.
Do not set the water tank without having the water tray in place. Otherwise, the water tank may tip over.
When you pull out the water tray, be careful not to scratch the floor with bottom of the tray.
CAUTION
Note
Do not leave the detached water tank with its cap closed.
Inner pressure of the tank changes according to ambient temperature change and may cause water
leakage or injury due to deformation or damage.
Humidifying function works automatically when the water tank and water tray are filled with water.
If you do not need humidification, operate the unit without filling water in the water tank and water tray.
CAUTION
When you remove the water tank, water may
drip from the tank cap. Lay a dry cloth before
