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.

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.

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.).
SAFETY PRECAUTION
•Check that all the information necessary for the correct
installation of the system is included in the Installation and
Operation Manuals provided with the outdoor and indoor
units. Please contact your distributor if it is not the case.
•The installation of refrigerant tubing shall be kept to a
minimum. Refrigerant tubing outside the cabinet shall be
protected to avoid mechanical damage and shall not be
installed in an unventilated space. It shall not be handled
or used for carrying during moving of the units. Flexible
refrigerant connectors (such as connecting lines between
the indoor and outdoor unit) may be displaced during normal
operation.
Low temperature solder alloys, such as lead/tin alloys, are
not acceptable for pipe connections.
Brazed, welded or mechanical connection shall be made
before opening the valves to permit refrigerant to ow
between refrigerant system parts. When mechanical
connectors are reused indoors, sealing parts shall be
renewed. When ared joints are reused indoors, the are
parts shall be re-fabricated. Mechanical connections shall be
accessible for maintenance purposes.
If any part of the system is installed in an unventilated area,
it shall be so constructed that should any refrigerant leak, it
will not stagnate so as to create a re or explosion hazard.
Any required ventilation opening shall be kept clear of
obstruction. Compliance with national gas regulations shall
be observed.
ELECTRICAL INSTALLATION
•The electrical installation must be performed according to
this Installation Manual and all the relevant regulations and
standards. Failure to follow these instructions can result in
shortage of capacity and reduced performance, leading to
electric shock and re.
•Do not install the unit in the following places, as this may
lead to the occurrence of re, deformations, rusting or
operation failure:
-Places where oil is present (including oil for machinery)
-Places with a high concentration of sulphurous gas, such
as spas
-Places with a saline, acidic or alkaline atmosphere
-Places where ammable gases may be generated or
circulate
-Places where silicon gas is present (depositions of silicon
gas on the surface of the heat exchanger act as a water
repellent, resulting in condensate water splashing out of
the collection tray and into the electrical box)
SERVICING
•Do not carry out maintenance, service and repair operations
by yourself. These operations shall be performed only by
qualied workers with the suitable tools and resources.
•Work shall be undertaken under a controlled procedure so
as to minimise the risk of ignition. All maintenance staff and
other staff in the area shall be instructed on the nature of
work being carried out. Work in conned spaces shall be
avoided.
•Ensure that the conditions within the area have been made
safe by control of ammable material. The area shall be
checked with an appropriate refrigerant detector prior to
and during work, to ensure that a potentially ammable
atmosphere is detected. The leak detection equipment used
shall be suitable for use with ammable refrigerants (i.e.,
non-sparking, adequately sealed and intrinsically safe)
• Appropriate re extinguishing equipment shall be available
on hand if any hot work is to be conducted. Please have a
dry powder or CO2 extinguisher next to the charging area.
Any source of ignition which may lead to the risk of re
IMPORTANT NOTICE
PMML0477 rev.1 - 10/2017
3

or explosion, including cigarette smoking, must be kept
sufciently far away from the working area, since refrigerant
may be released to the surrounding space. The area around
the equipment shall be checked before beginning the work
to make sure there is no risk of ignition or re hazard. “No
Smoking” signs shall be displayed.
•The area must be adequately ventilated before beginning the
work, and a degree of ventilation must be ensured while the
work is being carried out. Ventilation should safely disperse
any released refrigerant and preferably expel it externally
into the atmosphere.
•Repair and maintenance of electrical components shall
include initial safety checks and component inspection
procedures. If a fault compromises safety, then the circuit
shall not be connected to the power supply until the fault has
been solved satisfactorily. If the fault cannot be addressed
immediately, but it is necessary to resume operation, an
adequate temporary solution shall be applied. This shall be
reported to the owner of the equipment so all parties are
advised. Initial safety checks shall include:
-Capacitor discharge: This shall be done in a safe manner
to avoid sparks
-Exposure of live electrical components and wiring while
the system is being charged, recovered or purged
-Continuity of earth bonding
•During repair works, all the power supply connections must
be disconnected from the equipment before removing any
part such as a sealed cover. If it is absolutely necessary to
keep the power supply of the equipment during servicing,
then a permanently operating form of leak detection shall
be located at the most critical point to warn of a potentially
hazardous situation.
•Particular attention shall be paid not to alter the casing when
working on electrical components, in such a way that the
level of protection is affected. This includes the damage
to cables and seals, incorrect tting of glands, terminals
not made to original specication, excessive number of
connections, etc. The unit shall be mounted securely, and
the seals or sealing materials must not have been degraded
such that they no longer serve the purpose of preventing the
ingress of ammable atmospheres. Replacement parts shall
be in accordance with the manufacturer specications.
?NOTE
The use of silicon sealant may inhibit the effectiveness of some types of
leak detection equipment.
•Do not apply any permanent inductive or capacitive load
to the circuit without rst making sure that this will not
exceed the permissible voltage and current permitted for the
equipment in use.
Intrinsically safe components do not have to be isolated
before working on them. They are the only type which can
be worked on while live in the presence of a ammable
atmosphere. The test apparatus shall be at the correct
rating.
Check that wiring is not subject to wear, corrosion, excessive
pressure, vibration, sharp edges or any other cause of
damage. The check shall also take into account the effect
of ageing or continual vibration from sources such as
compressors of fans.
• Electronic leak detectors shall be used to detect ammable
refrigerants, but the sensitivity may not be adequate, or may
need recalibration. (Detection equipment shall be calibrated
in a refrigerant-free area)
Under no circumstance shall potential sources of ignition be
used for searching or detecting refrigerant leaks. A halide
torch (or any other detector using a naked ame) shall not
be used.
It must be ensured that the detector is not a potential source
of ignition while being suitable for the refrigerant used. Leak
detection equipment shall be set to a percentage of the LFL
(0.307 kg/m3) of the refrigerant and shall be calibrated to the
refrigerant employed and the appropriate percentage of gas
to conrm (25% maximum).
The use of leak detection uids like detergents containing
chlorine shall be avoided as the chlorine may react with the
refrigerant and corrode the copper pipework.
• If a leak is suspected, all the naked ames shall be
extinguished. If a leakage of refrigerant is found which
requires brazing, the refrigerant shall be either entirely
recovered from the system, or isolated in a part of the
system remote from the leak by means of shut off valves.
Oxygen-free nitrogen (OFN) shall then be purged through
the system, both before and during the brazing process.
•The procedure below shall be followed when breaking
into the refrigerant circuit to make repairs or for any other
purpose:
-remove refrigerant;
-purge the circuit with inert gas;
-evacuate;
-purge again with inert gas;
-open the circuit by cutting or brazing.
•The refrigerant charge shall be recovered into the correct
recovery cylinders. The system shall be “ushed” with
Oxygen free nitrogen (OFN) to render the unit safe.
This process may need to be repeated several times.
Compressed air or oxygen shall not be used for this task.
Flushing shall be achieved by breaking the vacuum in the
system with OFN and continuing to ll until the working
pressure is achieved, then venting to atmosphere, and
nally pulling down to a vacuum. This process shall be
repeated until no refrigerant is within the system. When the
nal OFN charge is used, the system shall be vented down
to atmospheric pressure to enable work to take place. This
operation is absolutely vital if brazing operations on the
pipework are to take place.
Ensure that the outlet for the vacuum pump is not close to
any ignition sources and there is ventilation available.
•In addition to conventional charging procedures, the
following requirements shall be followed.
-Ensure that contamination of different refrigerants
does not occur when using charging equipment. Hoses
IMPORTANT NOTICE
PMML0477 rev.1 - 10/2017

ENGLISH
or lines shall be as short as possible to minimise the
amount of refrigerant contained in them.
-Cylinders shall be kept upright.
-Ensure that the refrigeration system is earthed prior to
charging the system with refrigerant.
-Label the system when charging is complete (if not
already).
-Extreme care shall be taken not to overll the
refrigeration system.
•Prior to recharging the system it shall be pressure tested
with OFN. The system shall be leak tested on completion
of charging but prior to commissioning. A follow up leak test
shall be carried out prior to leaving the site.
• Replace components only with parts specied by HITACHI.
Other parts may result in the ignition of refrigerant in the
atmosphere from a leak.
DECOMMISSIONING
•Before carrying out decommissioning, it is essential that
the technician is completely familiar with the equipment
and all its detail. It is recommended good practice that all
refrigerants are recovered safely.
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.

• Check that the ceiling surface is at and suitable for the air
panel installation. If the ceiling is not at, drain water could
not ow smoothly.
?NOTE

•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.
•"STATIC PRESSURE SW" on the PCB must be set to HIGH
PRESSURE when installing the indoor unit at a height
of more than 2500 mm from the oor. It must be set to
NORMAL when installing the indoor unit at a height of less
than 2500 mm from the oor.

?NOTE
• Ceiling work differs depending on the building structure. Consult with
a building constructor or an interior nish worker for more information.
• Do not install electric light and the indoor unit to the same furring
of the ceiling. Otherwise, electric lights may icker or vibrate due to
indoor unit operation.
Mounting of suspension bolts
•Strengthen the opening parts of the false ceiling. Using a
steel C-prole makes the work easier.
•Mount suspension bolts, as shown.
