Consult your local authorities for the name and  
address of the waste materials collecting  
centers and waste paper disposal services  
nearest to your house.  
Before disposing an old air conditioner  
that goes out of use, please make sure it's  
inoperative and safe. Unplug the air  
conditioner in order to avoid the risk of  
child entrapment.  
Safety Instructions and Warnings  
Before starting the air conditioner, read the  
information given in the User's Guide  
carefully. The User's Guide contains very  
important observations relating to the  
assembly, operation and maintenance of the  
air conditioner.  
It must be noticed that air conditioner  
system contains refrigerants, which require  
specialized waste disposal. The valuable  
materials contained in a air conditioner can  
be recycled. Contact your local waste  
disposal center for proper disposal of an  
old air conditioner and contact your local  
authority or your dealer if you have any  
question. Please ensure that the pipework  
of your air conditioner does not get  
damaged prior to being picked up by the  
relevant waste disposal center, and  
contribute to environmental awareness by  
insisting on an appropriate, anti-pollution  
method of disposal.  
The manufacturer does not accept  
responsibility for any damages that may  
arise due to non-observation of the following  
instruction.  
Damaged air conditioners are not to be  
put into operation. In case of doubt, consult  
your supplier.  
Use of the air conditioner is to be carried  
out in strict compliance with the relative  
instructions set forth in the User's Guide.  
Disposal of the packaging of your new  
air conditioner  
All the packaging materials employed in  
the package of your new air conditioner  
may be disposed without any danger to the  
environment.  
Installation shall be done by professional  
people, don't install unit by yourself.  
For the purpose of safety, the air  
conditioner must be properly grounded in  
accordance with specifications.  
The cardboard box may be broken or cut  
into smaller pieces and given to a waste  
paper disposal service. The wrapping bag  
made of polyethylene and the polyethylene  
foam pads contain no fluorochloric  
hydrocarbon.  
Always remember to unplug the air  
conditioner before opening inlet grill. Never  
unplug your air conditioner by pulling on the  
power cord. Always grip plug firmly and  
pull straight out from the outlet.

Cautions  
All electrical repairs must be carried out  
by qualified electricians. Inadequate repairs  
may result in a major source of danger for  
the user of the air conditoiner.  
Do not damage any parts of the air  
conditioner that carry refrigerant by  
piercing or perforating the air conditioner's  
tubes with sharp or pointed items, crushing  
or twisting any tubes, or scraping the  
coatings off the surfaces. If the refrigerant  
spurts out and gets into eyes, it may result  
in serious eye injuries.  
Do not obstruct or cover the ventilation  
grille of the air conditioner. Do not put  
fingers or any other things into the  
inlet/outlet and swing louver.  
Do not allow children to play with the air  
conditioner. In no case should children be  
allowed to sit on the outdoor unit.

Caution! Injury to people of damages to machine might happen, if it is not observed.  
WARNING!  
Installation shall be done by professional people, don't install unit by yourself. Incorrect installation will  
cause water leakage, electric shock or fire.  
Install unit as per the Manual. Incorrect installation will cause water leakage, electric shock or fire  
accident.  
Be sure to use specified accessaries and parts. Otherwise, water leakage, electric shock, fire accident or  
unit falling down may happen.  
Unit should be placed on a place strong enough to hold the unit. Or, unit will fall down causing injuries.  
When install the unit, take in consideration of storms, typhoom, earthquake. Incorrect installation may  
cause unit to fall down.  
All electric work shall be done by experienced people as per eocal code, regulations and this Manual.  
Use exclusive wire for the unit. Incorrect installation or undersized electric wire may cause electric  
shock or fire accident.  
All the wires and circuit shall be safe. Use exclusive wire firmly fixed. Be sure that external force  
will not affect terminal bolck and electric wire. Poor contact and installation may cause fire accident.  
Arrange wire correctly when connectin indoor and outdoor power supply. Fix terminal cover firmly to  
avoid overheat, electric shock or even fire accident.  
In case retrigerant leakage occurred during unit installation, keep a good ventilation in the room.  
Poisonous gas will occur when meet with fire.  
Check the unit upon installation. Be sure there is no leakage. Refrigerant will induce poisonous gas  
when meet heat source as heater, oven, etc.  
Cut power supply before touching terminal bolck.  
CAUTION!  
Unit shall be grounded. But grounding shall not be connected to gas pipe  
water pipe, telephone line. Poor grounding will cause electric shock.  
Be sure to install a leakage breaker to avoid electric shock.  
Earthing  
Arrange water drainage according to this Manual. Cover pipe with insulation materials in case  
dew may occur. Unproper installation of water drainage will cause water leakage and wer your furniture.  
To maintain good picture or reduce noise, keep at least 1 m from T.V. radio, when install indoor and ou  
tdoor unit, connecting wire and power line. (If the radio wave is relatively strong, 1 m is not enough  
to reduce noise).  
Don't install unit in following places:  
(a) Oil mist or oil gas exists, such as kitchen, or, plastic parts may got aged, or water leakage.  
(b) Where there is corrosive gas. Copper tube and welded part may be damaged due to corrosion,  
causing leakage.  
(c) Where there is strong radiation. This will affect unit's control system, causing malfunction of the unit  
(d) Where flamable gas, dirt, and volatile matter (thinner, gasoline) exist, These matter  
might cause fire accident.  
Refer to paper pattern when installing unit.  
Cautions for the installation personnel  
Don't fail to show customers how to operate unit.

Installation Procedure  
1
. BEFORE INSTALLATION  
<Don't discard any accessories until comp>  
Determine the way to carry unit to installation place.  
Don't remove packing until unit reaches installation place.  
If unpacking is unkavoidable, protect unit properly.

2. SELECTION OF INSTALLATION PLACE  
(1) Installation place shall meet the following and agreed by customers:  
Place where proper air flow can be ensured.  
No block to air flow.  
Water drainage is smpoth.  
Place strong enough to support unit weight.  
Place where inclination is not evident on ceiling.  
Enough space for mainenance.  
Indoor and outdoor unit piping length is within limit. (Refer to Installation Manual for outdoor unit.)  
Indoor and outdoor unit, power cable, inter unit cable are at least 1 m away fromT.V. radop. This is helpful  
to avoid picture disturbance and noise. (Even if 1 m iskept, noise can still appear if radio wave is strong)  
(2) Ceiling height  
Indoor unit can be installed on ceiling of 2.5-3m in height. (Refer to Foeld setting and Installation Manual of  
ornament panel.)  
(3) Install suspending bolt. Check if the installation place is strong enough to hold weight. Take necessary  
measures in case it is not safe. (Distance between holes are marked on paper pattern. Refer to paper pattern  
for place need be reinforced)
