Carefully read through the procedure before start-
ing installation work.

Explanation for outdoor unit is in “How To Use”
(Instruction Manual) that is packed with outdoor unit.
Tools Needed For Installation Work
WARNING ........ Incorrect methods of installation may cause death or serious injury.
CAUTION ......... Improper installation may result in serious consequence.
Make sure to connect earth wire.
This sign in the fi gures indicates prohibition.

SAFETY PRECAUTION
l Read the safety precautions carefully before operating the unit.
l The contents of this section are vital to ensure safety. Please pay special attention to the following sign.
Be sure that the unit operates in proper condition after installation. Explain to customer the proper way of operating
the unit as described in the user’s guide.
WARNING
!
l Please request your sales agent or qualifi ed technician to install your unit. Water leakage, short circuit or fi re may occur if
you do the installation work yourself.
l Unauthorized modifi cations to the air conditioner may be dangerous. If a breakdown occurs please call a qualifi ed air
conditioner technician or electrician. Improper repairs may result in water leakage, electric shock and fi re, etc.
l Be sure to connect the earth wire from the power supply wire to the outdoor unit and between the outdoor and indoor
unit. Improper earthing may cause electric shock.
l Please observe the instructions stated in the installation manual during the process of installation. Improper installation may
cause water leakage, electric shock and fi re.
l Make sure that the units are mounted at locations which are able to provide full support to the weight of the units. If not,
the units may collapse and impose danger.
l Observe the rules and regulations of the electrical installation and the methods described in the installation manual when
dealing with the electrical work. Use wire which is approved offi cial in your country. A short circuit and fi re may occur due
to the use of low quality wire or improper work.
l Be sure to use the specifi ed wire for connecting the indoor and outdoor units. Please ensure that the connections are tight
after the conductors of the wire are inserted into the terminals. Improper insertion and loose contact may cause over-heating
and fi re.
l Please use the specifi ed components for installation work. Otherwise, the units may collapse or water leakage, electric shock
and fi re may occur.
l When installing or transferring an air conditioner to another location, make sure that air other than the specifi ed refrigerant
(R410A) does not enter the refrigeration cycle. If other air should enter, the pressure level of the refrigeration cycle may
increase abnormally high leading to possibility of unit rupture.
l Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact with fi re, a poisonous
gas may occur.
l After completion of installation work, check to make sure that there is no refrigeration gas leakage. If the refrigerant gas
leaks into the room, coming into contact with fi re in the fan-driven heater, space heater, etc., a poisonous gas may occur.
l Be sure to use the specifi ed piping set for R410A. Otherwise, this may result in broken copper pipes or faults.
l When installing or removing an air conditioner, do not allow air or moisture to remain in the refrigeration cycle. Otherwise,
pressure in the refrigeration cycle may become abnormally high so that a rupture may be caused.
CAUTION
!
l A circuit breaker must be installed in the house distribution box for the direct connected power supply wire to the outdoor
unit. In case of other installations a main switch with a contact gap or more than 3mm has to be installed. Without a circuit
breaker, the danger of electric shock exists.
l Do not install the unit near a location where there is fl ammable gas. The outdoor unit may catch fi re if fl ammable
gas leaks around it. Piping shall be suitable supported with a maximum spacing of 1m between the supports.
l Please ensure smooth fl ow of water when installing the drain hose.
l An IEC approved power cord should be used. Power cord type: NYM.
THE CHOICE OF MOUNTING SITE
(Please note the following matters and obtain permission from
customer before installation.)
!
WARNING
l The unit should be mounted at stable, non-vibratory
location which can provide full support to the unit.
!
WARNING
l No nearby heat source and no obstruction near the air
outlet is allowed.
l The clearance distances from top, right and left are
specifi ed in fi gure below.
l The location must be convenient for water drainage and
pipe connection with the outdoor unit.
l To avoid interference from noise, please place the unit
and its remote controller at least 1m from the radio and
television.
l To avoid any error in signal transmission from the remote
controller, please put the controller far away from high-
frequency machines and high-power wireless systems.

[Indoor unit installation]
CAUTION
Always install the indoor unit at level. If the
indoor unit is inclined, water may leak.
!
Be sure to completely
seal any gap with putty.
l The connecting pipe,
irrespective of the size,
should all be insulated
with insulation pipe and
then wrapped with vinyl
tape. (The insulator will
deteriorate if it is not
wrapped with tape).
Drain pipe
Must be installed separately.
Insulate indoor part of pipe to
prevent condensation.
The indoor piping should
be insulated with the
enclosed insulation pipe. (If
the insulator is insuffi cient,
please use commercial
products.)
l “Height difference” and “Piping length” of Indoor and Outdoor unit are different by Outdoor unit.
Please refer to the installation manual in Outdoor unit.

2. Installation procedure and notice
Select the installation location carefully for the split type
air conditioner. It is very diffi cult to move a split type air
conditioner after the fi rst installation.
2.1 Make a hole on the wall as shown in Fig. 2-1.
l The hole on the wall
should be made
with some inclination
like Fig. 2-1 to keep
the smooth fl ow of
condensed water.
2.2 Connecting pipe installation
l Seal the end of the pipes to prevent damage from
moisture and water.
2.3 Drain pipe installation
l Use PVC pipe VP20 (O.D. 25mm) for drain pipe.
l You must roll an insulation (thickness 10mm or more) over the indoor section of the drain pipe.
l Position the drain pipe in the downward direction to enable free-fl ow of water. Fix it with a hanger and avoid twisting the pipe as
shown in Fig. 2-3.
2.4 Installation method of unit type
INSTALLATION OF FULL DUCT TYPE
l Select the indoor unit position, fi xing direction of air outlet so
that cool/hot air reaches all the room. Standard position of
the indoor unit is with the wall side on the ceiling.
l Remove the factory fi tted fi lter and fi lter holders before installing
of full duct type.
l Secure the space for installation, inspection or servicing.
l Apply water-proof treatment to back surface of ceiling under the indoor unit, to prevent water drop.
