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 in-
door 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 in-
door 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 ca-
•
pacity.
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.
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 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 oper-
ation described in this Manual may result in operating failure in-
cluding potentially serious faults, or even the destruction of the air
conditioning system.

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 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 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.
N O T E
The air in the room should be renewed and the room ventilated
•
every 3 or 4 hours.
The system fitter and specialist shall provide anti-leak safety in
•
accordance with local regulations.
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 person-
nel 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.
