Disposal of the old ai conditione
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, anti-pollution method of disposal.
Disposal of the packaging of you new ai conditione
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 Inst uctions and Wa nings

Ope ation Tips
Heating Pe fo mance
Mic ocompute -cont olled Automatic Def osting
This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat indoors.
As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insufficient heating
perfomance is being produced, we recommend you use this air conditioner in conjunction with another kind of
heating appliance.
Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time
may be required after first starting the air conditioner until the room is heated.
When using the Heating mode under conditions of low outdoor air temperature high humidity, frost may form on the outdoor
unit, resulting in reduced operating performance.
In order to prevent this kind of reduced performance, this unit is equipped with a Microcomputer-controlled Automatic
Defrosting function. If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will operate briefly (for
about 7 to 15 minutes).
Inst uctions elating to heating a e applicable only to "HEAT & COOL TYPE"

Followings a e not p oblems
Sound of water flowing is not a problem.
Sound of cracking is heard.
Smell are generated.
During operation, white fog or steam
comes out from the indoor unit.
No outlet air or fan speed can't be changed
in dry mode.
In cooling operation, unit switches to
blowing operation.
Won't start?
In heating operation, water or steam
are blown out of outdoor unit.
In heating operation, indoor fan won't stop
even if unit is stopped.
During unit operation or at stop, a swishing or gurgling noise may be heard.
This noise is generated by refrigerant flowing in the system.
Unit will not restart after stop.
During unit operation, a cracking noise may be heard.
This noise is generated by the casing expanding or shrinking because of
temperature changes.
This is because the system circulates smells from the interior air such as
the smell of cigarettes or the painting on the furniture.
When unit is running at places like restaurant, etc. where dense edible oil
fumes always exist, this will happen.
To prevent frost from accumulating on indoor heat exchanger, unit will switch
to blowing operation for a while then resume cooling operation.
Though N/ FF button is set to N, the unit won't
resume cooling, dry or heating operation in 3 min
after it is stopped, this is because of
3-min-delay protection circuit.
Please wait 3 minutes
Unit will reduce fan speed repeatedly and automatically if room temp. is
too low in dry operation.
This occurs when frost accumulated on the outdoor unit is removed (during
defrosting operation).
After unit stop, indoor fan will go on running until indoor unit cools down.
