● Carefully read through the procedures of proper
installation before starting installation work.
● The sales agent should inform customers regarding
the correct operation of installation.
SAFETY PRECAUTION
!
!
!
!
● A circuit breaker or fuse must be installed. Without a circuit breaker or fuse the danger of electric shock exists.
A main switch with a contact gap of more than 3mm has to be installed in the power supply line to the outdoor unit.
● Do not install the unit near a location where there is Á ammable gas. The outdoor unit may
catch À re if Á ammable gas leaks around it.
● Please ensure smooth Á ow of water when installing the drain hose.
● Piping shall be suitable supported with a max imum spacing of 1m between the supports.
● Please request your sales agent or qualiÀ ed technician to install your unit. Water leakage, short circuit or À re may occur if
you do the installation work yourself.
● Please observe the instructions stated in the installation manual during the process of installation. Improper installation may
cause water leakage, electric shock and À re.
● 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 .
● Observe the rules and regulations of the electrical installation and the methods described in the installation manual when
dealing with the electrical work. Use power cables approved by the authorities of your country .
● Be sure to use the speciÀ 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 À re.
● Please use the speciÀ ed components for installation work. Otherwise, the units may collapse or water leakage, electric shock
and À re may occur .
● Be sure to use the speciÀ ed piping set for R410A. Otherwise, this may result in broken copper pipes or faults.
● 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.
● Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact with À re, a poisonous
gas may occur .
● 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 À re in the fan-driven heater , space heater , etc., a poisonous gas may occur .
● Unauthorized modiÀ cations to the air conditioner may be dangerous. If a breakdown occurs please call a quali À ed air
conditioner technician or electrician. Improper repairs may result in water leakage, electric shock and À re, etc.
FOR SERVICE PERSONNEL ONL Y
THE CHOICE OF MOUNTING SITE (Please note the following matters and obtain permission from customer before installation).
!
● The unit should be mounted at stable, non-vibratory location
which can provide full support to the unit.
!
● The Outdoor unit must be mounted at a location which can sup-
port heavy weight. Otherwise, noise and vibration will increase.
!
●
No nearby heat source and no obstruction near the air outlet is allowed.
●
The clearance distances from top, right and left are speciÀ ed in À gure
below .
●
The location must be convenient for water drainage and pipe connection
with the Outdoor unit.
●
T o avoid interference from noise please place the unit and its remote
controller at least 1m from the radio, television and inverter type
Á uorescent lamp.
●
T o 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.
●
The installation height of indoor unit must be 2.3m or more.
!
●
Do not expose the unit under direct sunshine or rain. Besides, ventilation
must be good and clear of obstruction.
●
The air blown out of the unit should not point directly to animals or plants.
●
The clearances of the unit from top, left, right and front are speciÀ ed in
À gure below . At least 3 of the above sides must be open air .
●
Be sure that the hot air blown out of the unit and noise do not disturb the
neighbourhood.
●
Do not install at a location where there is Á ammable gas, steam, oil and
smoke.
●
The location must be convenient for water drainage.
●
Place the Outdoor unit and its connecting cord at least 1m away from the
antenna or signal line of television, radio or telephone. This is to avoid noise
interference.
●
Do not install outdoor unit facing strong wind direction. It may damage the
fan motor .

● The draining of the water container inside the indoor unit can be done from the
left. Therefore the hanger must be À xed horizontally or slightly tilted towards the
side of drain hose. Otherwise, condensed water may overÁ ow the water container .
Direct Mounting On The W all
● Please use hidden beams in the wall to hold the hanger .
W all Penetration and Installation of Protection Pipe
● Drill a ø 65mm hole on
wall which is slightly tilted
towards the outdoor side.
Drill the wall at a small
angle.
● Cut the protection pipe
according to the wall
thickness.
● Empty gap in the sleeve
of protection pipe should
be completely sealed with
putty to avoid dripping of

Preparation
Change of Drain Hose and Installation Procedures.
●
Ex change the location of drain hose and drain cap during horizontal piping as shown in
À gure below . Be sure to plug in the drain hose until the insulating material folds upon itself.
● Please use pliers to pull out the drain cap.
(This is an easier way to remove the drain cap).
INST ALLA TION OF REFRIGERA TING PIPES AFTER CONNECTION
● The refrigerating pipes should be adjusted to À t into the
hole on the wall and then ready for further connection.
● The terminals of 2 connected pipes must be covered
with insulator used for terminal connection. Then the
pipes are wrapped with insulation pipe.
● Connect the connecting cord after removing electrical
cover . (Refer to “CONNECTION OF POWER CORD”)
● After adjustment, À t the connecting cord and pipes
into the space available under the indoor unit. Use
holder to hold them tight.
!
CAUTION
●
The rubber strap used for
À xing the insulator should
not be tied with great force.
Otherwise, this will damage
heat insulation and causes
water condensation.
● Holder can be attached at the either of 2 places.
Please select the easier position.

CAUTION
!
Y ou are free to choose the side (left or right) for the installation of drain
hose. Please ensure the smooth Á ow of condensed water of the Indoor
unit during installation. (Carelessness may result in water leakage.)
!
CAUTION
Be sure that the
drain hose is not
loosely connected
or bend.
Be sure that the wire is not
in contact with any metal
in the wall. Please use
the protection pipe as wire
passing through the hollow
part of the wall so as to
prevent the possibility of
damaged by mouse.
Unless it seals completely ,
any air with high humidity
flows from outdoor and
any dew may drop.
