• 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.

1.4 PURPOSE OF THIS MANUAL
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.
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.

!CAUTION
• Do not install the indoor units in a ammable environment to avoid a
re or an explosion.
• Check to ensure that the ceiling slab is strong enough. If not strong
enough, the indoor unit may fall down on you.
• Do not install the indoor units, outdoor unit, remote control switch and
cable within approximately 3 meters of strong electromagnetic wave
radiators such as medical equipment.
• Do not install the indoor units in a machinery shop or kitchen where
vapor from oil or mist ows to the indoor units. The oil will deposit on
the heat exchanger, thereby reducing the indoor unit performance,
and may deform. In the worst case, the oil damages the plastic parts
of the indoor unit.
• To avoid any corrosive action to the heat exchangers, do not install
the indoor units in an acid or alkaline environment.
• When lifting or moving the indoor unit, use appropriate slings to avoid
damage and be careful not to damage the insulation material on units
surface.

Mounting the suspension bolts
-Using the dimension shown above select the nal
location and installation direction of the Indoor Unit
paying careful attention to the space for the piping, wiring
and maintenance.
-Install the sling bolts, M10 or greater are also
recommended, and suspend the indoor unit using the
following steps:
1 Hook suspension bracket to the nut and washer of each sling
bolt, as shown, starting from one side.
2 After check the nut and washer are correctly xes by the
retainers of the suspension bracket, hook the suspension
bracket of the other side to nut and washer.

-Make sure that the foundation is at, taking into account
the maximum foundation gradient.
-The unit should be installed so that one side of the unit
is slightly (approximately 5 mm) lower than the other
side, in order to avoid the incorrect position of the drain
discharge.
Tighten the nuts of the suspension bolts with the suspension
brackets after adjustment is completed. Special plastic paint
must be applied to the bolts and nuts in order to prevent them
from loosening.
?NOTE
Keep the unit as well as relevant equipment covered with the vinyl cover
during installation work.

5 DRAIN PIPING
5.1 GENERAL
?NOTE
Install drainage in accordance with national and local codes.
!CAUTION
• Do not create an upper-slope or rise for the drain piping, since drain
water will ow back to the unit and leakage to the room will occur
when the unit operation is stopped.
• Do not connect the drain pipe with sanitary or sewage piping or any
other drainage piping.
• When the common drain piping is connected with other indoor units,
the connected position of each indoor unit must be higher than the
common piping. The pipe size of the common drain pipe must be
large enough according to the unit size and number of unit.
Common drain piping
1/25~1/100 Down Slope
• Drain piping will require insulating if the drain is installed in a location
where condensation forming on the outside of drain pipe may drop
and cause damage. The insulation for the drain pipe must be selected
to insure vapor sealing and prevent condensation forming.
• Drain trap should be installed next to indoor unit. This trap must be
designed to good practice and be checked with water (charged)
and tested for correct ow. Do not tie or clamp the drain pipe and
refrigerant pipe together.
After performing drain piping work and electrical wiring, check to
ensure that water ows smoothly as in the following procedure:
 Checking with drain-up mechanism and oat
switch
-Switch ON the power supply.
-Pour approximately 1.8 liters of water into the drain pan.
Then oat switch stops the system automatically. In this
operations the drain pump do not stops.
-Check to ensure that the water ows smoothly or whether
no water leakage occurs. When water cannot be found
at the end of the drain piping, pour another approximately
1.8 liters of water into the drain pan.
-Switch OFF the power supply after.
?NOTE
Pay attention to the thickness of the insulation when the left side piping is
performed. If it is too thick, piping can not be installed in the unit.
5.2 DRAIN PIPE CONNECTION
1 Prepare a polyvinyl chloride pipe with a 32 mm outer
diameter.
2 Fasten the tubing to the drain hose with an adhesive and
the clamp. The drain piping must be performed with a down-
slope pitch of 1/25 to 1/100.
