!DANGER
• HITACHI is not able to foresee all the circumstances which may
result in a potential danger.
• Do not pour water in the indoor or outdoor unit. These prod-
ucts are tted with electric components. If water comes into con-
tact with electric components, this will cause a serious electric
shock.
• Do not handle or adjust the safety devices inside the indoor and
outdoor units. The handling or adjustment of these devices may
result in serious accident.
• Do not open the service cover or access panel of the indoor and
outdoor units without disconnecting the main supply.
• In the event of re, switch off the mains, put out the re immedi-
ately and contact your service supplier.
• Check that the earth cable is correctly connected.

the air in the room.
• Fit the indoor unit, the outdoor unit, the remote control and the
cable at a minimum of 3 metres away from sources of strong
radiation from electromagnetic waves, such as medical equip-
ment.
• Do not use sprays, such as insecticides, varnishes or enamels
or any other inammable gas within a metre of the system.
• If the circuit breaker or supply fuse of the unit comes on fre-
quently, stop the system and contact the service suppler.
• Do not carry out maintenance or inspection work yourself. This
work must be carried out by qualied service personnel with
suitable tools and resources for the work.
• Do not place any foreign material (branches, sticks, etc.) in the
air inlet or outlet of the unit. These units are tted with high
speed fans and contact with any object is dangerous.

dle this appliance properly and safely.
• Children should be supervised to ensure that they do not play
with the appliance.

1.4 PURPOSE OF THIS MANUAL
This air conditioning system has been exclusively designed to
supply air conditioning to people in one or more rooms within the
installation range of the system.
The air conditioning system must not be used for other purpose
such as drying clothes, cooling food or any other process
requiring cooling or heating.
The air conditioning system should only be installed by qualied
personnel, with the necessary resources, tools and equipment,
who are familiar with the safety procedures required to
successfully carry out the installation.
The supplementary information about the purchased products
is supplied in a CD-ROM, which can be found bundled with the
outdoor unit. In case that the CD-ROM is missing or it is not
readable, please contact your Hitachi dealer or distributor.
PLEASE READ THE MANUAL AND THE FILES ON THE
CD-ROM CAREFULLY BEFORE STARTING WORK ON THE
INSTALLATION OF THE AIR CONDITIONING SYSTEM.
Failure to observe the instructions for installation,use and
operation described in this documentation may result in
operating failure including potentially serious faults, or even the
destruction of the air conditioning system.
It is assumed that the air conditioning system will be installed
and maintained by responsible personnel trained for the
purpose. If this is not the case, the customer should include all
the safety, caution and operating signs in the native language of
the personnel responsible.
Do not install the unit in the following places, as this may lead to
a re, deformities, rusting or faults:
• Places where oil is present (including oil for machinery).
• Places with a high concentration of sulphurous gas, such as
spas.
• Places where ammable gases may be generated or
circulate.
• Places with a saline, acidic or alkaline atmosphere.
Do not install the unit in places where silicon gas is present. Any
silicon gas deposited on the surface of the heat exchanger will
repel water. As a result, the condensate water will splash out
of the collection tray and into the electrical box. Water leaks or
electrical faults may eventually be caused.
Do not install the unit in a place where the current of expelled
air directly affects animals or plants as they could be adversely
affected.
