PRECAUTIONS DURING OPERATION
●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.
●Do not place plants directly under the air flow as it is bad for the plants.
●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.
●When operating the unit with the door and windows opened, (the room humidity is always above
80%) and with the air deflector 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.
●Do not climb on the outdoor unit or put objects on it.
●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.

●The product shall be operated under the manufacturer specification and
not for any other intended use.
●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 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.

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 flows 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 pre-set the required operating modes
before sleep
Temperature sensing automatic dehumidification
Hitachi air conditioners are specially equipped with
précised and reliable temperature sensing automatic
dehumidification function, that automatically operates the
dehumidification 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
