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, anti-pollution method of disposal.
Disposal of the packa in 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 Warnin s
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.
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 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.
This appliance is not intended for use by persons (including children) with reducedphysical, sensory or mental capabilities, or
lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by
a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.

Cautions
The machine is adaptive in followin situation
Applicable ambient temperature range:
If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar qualified person.
If the fuse on PC board is broken please change it with the type of T 3.15A /250VAC. Please check the circuit diagram
about the fuse replaced.
The wiring method should be in line with the local wiring standard.
The power cable and connecting cable are self-provided. All the cables shall have got the local authentication certificate.
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.
The waste battery shall be disposed properly.

Operation
AW-SDM048-N11

Keep proper room temperature
Too cold or too warm is no good to your health, and power
consumption will be increased as well.
Air filter should be periodically cleaned
If air filter is clogged, it will cause poor cooling and heating
efficiency, higher power consumption and even problem
may occur. In cooling operation, water will flow out.
Use Timer effectively
You may use Timer mode to keep a comfortable room temp.
when you wake up or come home from outside.
Avoid direct sunlight and air flow Adjust air flow properly
Proper temp.

Ener y Savin

Don't spray any paint or insecticide on the unit.Don't splash water directly on indoor unit.
This will cause damage or even fire accident.
This could be
very dangerous
Disconnect power supply Don't touch it with wet hand Don't wash with hot water or solvent to
clean the unit
10
Maintenance
Pull it out from top as shown in Fig.
Wash it with clean water and install it after complete dry.
Air filter cleanin
Use water or vacuum cleaner to clean it. If it is extremely dirty,
wash it with neutral detergent or soap water.
Don't use hot water over 40 C, as this may cause damage to air filter.
Wipe air filter carefully.
Caution:
After season maintenance
Before season maintenance
Let the unit run in Fan mode for half a day in a fine weather to dry completely the unit inside.
Turn off the unit and pull out power plug. Otherwise, there might be certain power consumption
even if the unit is stopped.
Clean air filter and indoor unit, cover outdoor unit after cleaning.
Check if there are obstacles at inlet and outlet of indoor and outdoor unit, whick will reduce unit
efficiency.
Don't fail to attach air filter after making sure it is cleaned. Dust will enter into unit causing
damages or faults if it is running without air filter.
To protect compressor at start, please connect external power supply to the unit 12 hrs prior to
starting. Also please keep the power supply switch ON during the whole season.
Clean it with warm and wet cloth or with neutral detergent, then wipe it dry with clean and soft cloth.
If air conditioner is very dirty, clean it with cloth soaked in neutral detergent, then wipe off the detergent with clean water.
Don't use water higher than 40 C, which will cause discoloring and deformation.
Don't use insecticide or other chemical detergents.

Troubleshootin
Followin s are not problems
Sound of water flowings are not
problems.
Sound of cracking is heard.
Smells are generated.
During operation, white fog or
steam comes out of indoor unit.
In cooling operation, unit switches to fan
operation.
Unit will not restart after stop.
No outlet air or fan speed can't be changed
in dry mode.
In heating operation, water or steam are
blown out of indoor unit.
In heating operation, indoor fan won't stop
even if unit is stopped.
During unit start and operation or at stop, a swishing or gurgling noise may
be heard. 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 temperatuer changes.
This is because the system circulates smells from the interior air such as
the smell of cigarettes or the painting on the unit.
When unit is running at places like restaurant where dense edible oil fumeis
always exist, this will happen.
To prevent frost from accumulating on indoor heat exchanger, unit will switch
to fan operation for a while and then resume cooling operation.
Though ON/OFF button is set to ON, 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.
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 stops, indoor fan will go on running until indoor unit cools down.
Please wait 3 minutes
Won't start?

Before asking services, please firstly check your unit according to following.
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.
Water comes out in cooling/dry operation.
Operation is abnormal or sound is heard.
