Cautions
Disposal of the old air conditioner
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.
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,
antipollution method of disposal.
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.
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.
All these valuable materials may be taken
to a waste collecting center and used
again after adequate recycling.
Consult your local authorities for the name
and address of the waste materials
collecting centers and waste paper
disposal services nearest to your house.
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.
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.
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.

Cautions
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.
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 conditioner.
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 twistings 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.
Specifications
The refrigerating circuit is leak-proof.
10. The wiring diagram is attached in-
side the machine.
11. The appliance must be installed on
strong enough supporter.

Phenomenon
When unit is stopped, it won't restart
immediately until 3 minutes have elapsed 
to protect the system.
When the electric plug is pulled out and
reinserted, the protection circuit will work
for 3 minutes to protect the air conditioner.
Noise is heard.
The system does not restart
immediately.
During unit operation or at stop, a swishing 
or gurgling noise may be heard. At first 2-3 
minutes after unit start, this noise is more 
noticeable. (This noise is generated by 
refrigerant flowing in the system.)
During unit operation, a cracking noise may 
be heard. This noise is generated by the 
casing expanding or shrinking because of 
temperature changes.
Should there be a big noise from air flow in 
unit operation, air filter may be too dirty.
This is because the system circulates smells 
from the interior air such as the smell of 
furniture, cigarettes.
During COOL or DRY operation, indoor unit 
may blow out mist. This is due to the sudden
cooling of indoor air.
Does not work at all.
Is the air filter dirty? Normally it should be 
cleaned every 15 days.
Are there any obstacles before inlet and outlet?
Is temperature set correctly?
Are there some doors or windows left open?
Is there any direct sunlight through the 
window during the cooling operation?(Use

Are there too much heat sources or too many
people in the room during cooling operation?
