may catch fire if flammable gas leaks around it.

Please ensure smooth flow of water when installing the drain hose.•

PRECAUTIONS DURING SHIFTING OR MAINTENANCE

Should abnormal situation arises (like burning smell), please stop operating
the unit and turn off the circuit breaker. Contact your agent. Fault, shor t
circuit or fire may occur if you continue to operate the unit under abnormal
situation.

Please contact your agent for maintenance. Improper self maintenance may
cause electric shock and fire.

Please contact your agent if you need to remove and reinstall the unit.

PRECAUTIONS DURING OPERATION

The product shall be operated under the manufacturer specification and not

•

for any other intended use.

Do not attempt to operate the unit with wet hands, this could cause fatal accident.•

When operating the unit with burning equipments, regularly ventilate the

•

room to avoid oxygen insufficiency.

Do not direct the cool air coming out from the air-conditioner panel to face

•

household heating apparatus as this may affect the working of apparatus such as
the electric kettle, oven etc.

Please ensure that outdoor mounting frame is always stable, firm and

•

without defect. If not, the outdoor unit may collapse and cause danger.

Do not splash or direct water to the body of the unit when cleaning it as this may

•

cause short circuit.

Do not use any aerosol or hair sprays near the indoor unit. This chemical

•

can adhere on heat exchanger fin and blocked the evaporation water flow to
drain pan. The water will drop on tangential fan and cause water splashing
out from indoor unit.

Turn off the circuit breaker if the unit is not to be operated for a long period.•

Do not climb on the outdoor unit or put objects on it.•

Do not put water container (like vase) on the indoor unit to avoid water

•

dripping into the unit. Dripping water will damage the insulator inside the unit
and causes short-circuit.

Do not place plants directly under the air fl ow as it is bad for the plants.•

When operating the unit with the door and windows opened, (the room humidity is always above

•

80%) and with the air defl ector facing down or moving automatically for a long period of time,water
will condense on the air deflector and drips down occasionally. This will wet your furniture.Therefore,
do not operate under such c
If the amount of heat in the room is above the cooling or heating capability of the unit (for example:

•

more people entering the room, using heating equipments and etc.), the preset room temperature
cannot be achieved.

This appliance is not intended for use by young children or infirm persons unless they have been

adequately supervised by a responsible person to ensure that they can use this appliance safely.

Fuzzy control

The common timer controls will always switch on the
air conditioner at a predetermined time that could
cause over cooling, however, with this advanced
fuzzy control system the air conditioner will be either
switched on before preset time or delayed depending
on the indoor temperature changes, allowing the room
temperature to reach the preset temperature within an
optimal time frame, as such it will create an optimal air
conditioned environment and will also provide greater
savings on electrical energy consumption.

Low noise air intake system

This newly modified low noise air intake system allows
better and smoother air fl ows that will provide a quiet
and refreshing environment.

Sleep mode with automatic adjustable temperature
controls

After adjusting the sleep mode timer before sleep,
the t emp erature w ill be automatically controlled
and adjusted accordingly to the lowering or body
temperature during sleep and lower temperature
throu g h o u t the ni g h t , to p r o v i d e a c o n d u cive
environment for a good sleep.

An hour after setting the sleep mode timer, the air
conditioner wi ll automatically adjust the optimal
temperature; during summer it will be adjusted to 2°C
higher than the preset room temperature, and the timer
can be set at a 1-hour, 2-hour, 3-hour and 7-hour cycle.
All can be set by pressing the control buttons that save
you the trouble to preset the required operating modes
before sleep.

Temperature sensing automatic dehumidification

Hitachi air conditioners are specially equipped with
pricise and reliable temperature sensing automatic
dehumidifi cation function, that automatically operates
the dehumidifi cation whenever the room temperature
exceeds the preset temperature and it stops whenever
the room temperature falls back within the preset
temperature as such it stabilizes the temperature and
provides a more conducive environment for the user.

Well designed unit body

The indoor unit incorporates the latest design and has
a non-bulky body that measures 211 x 780 x 280mm.
