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, anti-pollution
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.

For the purpose of safety, the air
conditioner must be properly grounded in
accordance with specifications.
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 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.
Specifications
The refrigerating circuit is leak-proof.
For series 24,28,36,42,the breaker of
the air conditioner should be all-pole
switch;and the distance between its two
contacts should be no less 3mm.
Such means for disconnection must be
incorporation in the fixed wiring.

1. Press the two buttons on the filters, until you hear a sound of click.
2. Pull the filters upward to remove them from the Intake Grill.
CLEANING AND CARE
CAUTION!
Before cleaning the air conditioner ,be sure to turn it off and disconnect
the Power Supply Cord.
Be sure the Intake Grill is installed securely.
When removing and replacing the air filters, be sure not to touch the heat
exchanger, as personal injury may result.
3. Clean the air filter: Remove the dust from the filters by vacuum cleaner or washing them. After
washing, allow the air filters to dry thoroughly in an area protected from sunlight.
4. Re-attach the air filters to the Intake Grill, press the two buttons on the filters, until you hear
a sound of click.
When used for extended periods, the unit may accumulate dirt inside, which reduces its
performance. We recommend that the unit is inspected regularly, in addition to your own
cleaning and care. For more information, consult authorized service personnel.
When cleaning the unit's body, do not use water hotter than 40 C, harsh abrasive cleansers,
or volatile agents like benzene or thinner.
Do not expose the unit body to liquid insecticides or hairsprays.
When shutting down the unit for one month or more, first allow the Fan mode to operate
continuously for about half a day to allow internal parts to dry thoroughly.

TROUBLE SHOOTING
Followings are not problems
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 ON/OFF button is set
to ON, 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.
18
Before ask for services, please first check your unit against the following.
Air conditioner won't start.
Poor cooling or heating
Is power supply switch
turned on?
Power supply
switch is not
set at ON.
Is city power supply normal? Is leakage current breaker
activated?
This is very dangerous, please
disconnect power supply
immediately and contact your
dealer.
Are operation control
adjusted correctly
as specified?
Is air filter too dirty?
Are there any obstacles in inlet
or outlet grill?
Are horizontal louvers at
up position (in heating
mode)?
Any doors or windows left
open?
Is there any direct sunlight
in the room?
If there are unexpected heat
sources in the room?
Too many people in the room?
Poor cooling
Is air conditioner in standby
condition in heating mode?
Cold air blows out
(in heating mode)
If your unit still can't work properly after above mentioned
checks, or following problems occur, please stop it immediately
and contact your dealer.
Fuses or circuit breakers often blow out.

Operation and Performance
*Heating Performance
*Microcomputer-controlled Automatic Defrosting
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.
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.
Instructions relating to heating (*) are applicable
only to "HEAT & COOL TYPE".
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).
During Automatic Defrosting operation, the
OPERATION Indicator Lamp will flash.
*Trouble alarming performance
During operation, when there is any trouble,
the power indicator lamp will flash.

If the air conditioner is used under higher temperature condition than those listed, the built-in
protection circuit may operate to prevent internal circuit damage. Also, during Cooling and Dry
modes, if the unit is used under conditions of lower temperature than those listed above, the
heat-exchanger may freeze, leading to water leakage and other damage.
Do not use this unit for any other purposes except for the Cooling, (*) Heating, Dehumidifying,
and air-circulation of rooms in ordinary dwellings.
The wiring method should be in line with the local wiring standand.
The waste battery should be disposed properly.
If the fuse on PC board is broken, please change it with the type T 3.15A/250V.
The indoor unit installation height is at least 2.5m.
