GENERAL INFORMATION

PMML0477 rev.0 - 07/2017

2.2 ADDITIONAL INFORMATION ABOUT SAFETY

! 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 products

are tted 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 re, switch off the mains, put out the re

immediately and contact your service supplier.

• Check that the earth cable is correctly connected.

• Connect the unit to a circuit breaker of the specied capacity.

! CAUTION

• 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 inammable 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 qualied 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.

• 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.

? NOTE

• The air in the room should be renewed and the room ventilated every

3 or 4 hours.

• The system tter and specialist shall provide anti-leak safety in

accordance with local regulations.

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 qualied

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 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.

Do not reconstruct the unit. Water leakage, fault, short circuit or

re 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 re.

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 re 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

re 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.

IMPORTANT NOTICE

PMML0477 rev.0 - 07/2017

ENGLISH

During operation:

• Avoid an extended period of exposure to a direct air ow.

• Do not insert ngers, rods or other objects into the air outlet

or inlet. As the fan is rotating at high speed, it will cause

injury. Before cleaning, be sure to stop the operation and turn

the breaker OFF.

• Do not use any conductor as fuse wire. This could cause a

fatal accident.

• During thunderstorms, disconnect and turn off the circuit

breaker.

• Do not attempt to operate the unit with wet hands. This could

cause fatal accident.

• Do not direct the cool air coming out from the air conditioner

to household heating appliances (stoves, electric kettles,

ovens, etc.), as this may affect their operation.

• Please ensure that the outdoor mounting frame is always

stable, rm and without defects. Otherwise, the outdoor unit

may collapse and cause damage and injury.

• Do not splash or direct water to the body of the units when

cleaning them, as this may cause short circuit.

• Do not use any aerosol or hair sprays near the indoor unit.

Their chemicals can adhere to the ns of the heat exchanger

and block the ow of evaporation water to the drain pan.

Water will drop on the tangential fan and splash out from the

indoor unit.

• Switch off the units and turn off the circuit breaker during

cleaning.

• Do not climb on the outdoor unit or put objects on it.

• Do not put water containers (like a vase) on the indoor unit. If

water drips into the unit, it will damage the inside and cause

short circuit.

• When operating the unit with the door and windows opened

(relative humidity constantly above 80%) and with the air

deector facing down or moving automatically for a long

period of time, water will condense on the air deector

and drip down occasionally. This will wet your furniture.

Therefore, do not operate under such condition for an

extended time.

• The preset room temperature cannot be achieved if the

amount of heat in the room exceeds the cooling or heating

capacity of the unit (for example, if more people enters in the

room, if heating equipment is used, etc.).

4 BEFORE OPERATION

! CAUTION

• Supply electrical power to the system for approximately 12 hours

before start-up after long shutdown. Do not start the system

immediately after power supply, it may cause a compressor failure,

because the compressor is not heated well.

• Make sure that the outdoor unit is not covered with snow or ice. If

covered, remove it by using hot water (approximately 50ºC). If the water

temperature is higher than 50ºC, it will cause damage to plastic parts.

• When the system is started after a shutdown longer than approximately

3 months, it is recommended that the system be checked by your

service contractor.

• Turn OFF the main switch when the system is stopped for a long

period of time. If the main switch is not turned OFF, electricity is

consumed, because the oil heater is always energized during

compressor stopping.

4.1 EFFICIENT USE OF INDOOR UNIT

• Do not leave a window or a door open.

The operating efciency will be decreased.

It may cause dew condensation of the indoor unit. (Ventilate

a room sufciently too.)

• Attach a curtain or a blind to a window.

Direct sunlight is prevented and the cooling efciency will be

increased.

• Do not use heating appliances during the cooling operation

as possible.

The cooling efciency will be decreased. It may cause dew

condensation and dropping dew.

• Use a circulator if warm air stays around ceiling.

The comfortability will be increased. Contact your distributor

for the detail.

• Change the air ow direction downward if the ceiling surface

gets dirty.

It is recommended to change the air ow direction by approx.

30º downward from the levelness.

• Turn OFF the main power source if the indoor unit is not

used for a long time.

If not, the standby electricity charges will have to be paid

even if the indoor unit is unused.

• Select a suitable installation location, considering the air

distribution from each indoor unit to the whole room so that

room temperature will be uniform.

• Install the unit where there is no obstacles which may

hamper the suction air and discharged air.

• Do not install the unit near a door or a window where the

indoor unit may contact humid outside air. Otherwise, dew

condensation may occur.

• In case temperature and humidity inside the ceiling exceeds

30ºC/RH (Relative Humidity) 80%, apply additional insulation

materials to the external surface of the indoor unit to avoid

dew condensation.

• If installing the indoor unit to a high ceiling, the warmed air

may stay around the ceiling during heating operation. Thus,

the parallel installing of a circulator is recommended.

• Do not install the indoor unit where the airow from the air

outlet blows directly to the temperature detecting devices

such an alarm device or a control device. It may cause a

failure of an alarm device or a control device.

• Multiple Combinations. For simultaneous operation of

multiple units, the units must be installed in the same room

and be operated under the same conditions. If the room is

partitioned by a wall, furniture or a curtain, etc., it may cause

an operation failure. Take care when rearranging furniture or

remodelling the room after installation as well.

• When installing the receiver kit (optional) or the motion

sensor (optional), refer to their respective Installation

manuals.
