PRECAUTIONS DURING INSTALLATION
WARNING
Do not reconstruct the unit.
Water leakage, fault, short circuit or fire may occur if you reconstruct the unit
by yourself.
•
Please ask your sales agent or qualified technician for the installation of
your unit. Water leakage, short circuit or fi re may occur if you install the unit
by yourself.
•
Please use earth line.
Do not place the earth line near water or gas pipes, lightning-conductor, or
the earth line of telephone. Improper installation of earth line may cause
electric shock.
•
CAUTION
A circuit breaker should be installed depending on the mounting site of the
unit. Without a circuit breaker, the danger of electric shock exists.
•
Do not install near location where there is flammable gas. The outdoor unit
may catch fire if flammable gas leaks around it.
•
Please ensure smooth flow of water when installing the drain hose.•

PRECAUTIONS DURING OPERATION
W
A
R
N
I
N
G
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.
•
Please switch off the unit and turn off the circuit breaker during cleaning, the high-
speed fan inside the unit may cause danger.
•
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 condition for a long time.
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.
•

Fuzzy control
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.
Quiet
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 temperature will be automatically controlled
and adjusted accordingly to the lowering or body
temperature during sleep and lower temperature
throughout the night, to provide a conducive
environment for a good sleep.
An hour after setting the sleep mode timer, the air
conditioner will 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 221 x 780 x 280mm.
