!
D A N G E R
•
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 products
are fitted with electric components. If water comes into contact
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 fire, switch off the mains, put out the fire
immediately and contact your service supplier.
•
Check that the earth cable is correctly connected.
•
Connect the unit to a circuit breaker of the specified capacity.

C A U T I O N
•
Refrigerant leaks may hinder respiration as the gas displaces 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 equipment.
•
Do not use sprays, such as insecticides, varnishes or enamels or any
other inflammable gas within a metre of the system.
•
If the circuit breaker or supply fuse of the unit comes on frequently,
stop the system and contact the service suppler.
•
Do not carry out maintenance or inspection work yourself. This work
must be carried out by qualified 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 fitted with high speed fans
and contact with any object is dangerous.
•
This appliance must be used only by adult and capable people,
having received the technical information or instructions to handle
this appliance properly and safely.
•
Children should be supervised to ensure that they do not play with
the appliance.

3 IMPORTANT NOTICE
This air conditioner has been designed for standard air
conditioning for human beings. For use in other applications,
please contact your HITACHI dealer or service contractor.
The air conditioning system should only be installed by qualified
personnel, with the necessary resources, tools and equipment,
who are familiar with the safety procedures required to
successfully carry out the installation.
PLEASE READ AND FAMILIARISE YOURSELF
WITH THE MANUAL BEFORE STARTING WORK ON THE
INSTALLATION OF THE AIR CONDITIONING SYSTEM.
Failure to observe the instructions for installation, use and
operation described in this Manual 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. 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 fire, 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 flammable 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.
Do not reconstruct the unit. Water leakage, fault, short circuit or
fire may occur if you reconstruct the unit by yourself.
Please use an earth wire. Do not place the earth wire near
water or gas pipes, lightning conductors, or the earth wire of
a telephone. Improper installation of earth wiring may cause
electric shock or fire.
Should an abnormal situation occur (like a burning smell),
please stop operating the unit and turn off the circuit breaker.
Fire may occur if you continue to operate the unit in an
abnormal situation.
Please contact your agent if you need to remove and reinstall
the unit. Electric shock or fire may occur if you remove and
reinstall the unit improperly by yourself.
If the power supply cord is damaged, it must be replaced with
the special cord obtainable at authorized service/parts centres.
Please consult with your dealer if the air conditioner does not
cool, since refrigerant leakage may be considered as one of
the causes. The refrigerant gas used in the air conditioner is
harmless. However, harmful by-products may be generated if
the refrigerant gas leaks into the room and enters in contact with
fire or a source of heat such as a stove heater. In the event of a
gas leakage, immediately stop the air conditioner, open doors
and windows to ventilate the room thoroughly and contact your
dealer.
