Electrical Safety

▲ WARNING

• This appliance must be properly grounded.
To minimize the risk of electric shock, you must always plug into a grounded outlet.
- Do not cut or remove the grounding prong from the power plug.
- Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the appliance unless the cover screw is metal and not insulated, and the wall receptacle is grounded through the house wiring.
- If you have any doubt whether the air conditioner is properly grounded, have the wall receptacle and circuit checked by a qualified electrician.

Temporary Use of an Adapter

We strongly discourage the use of an adapter due to potential safety hazards. For temporary connections, use only a genuine adapter, available from most local hardware stores. Ensure that the large slot in the adapter is aligned with the large slot in the receptacle for a proper polarity connection.

To disconnect the power cord from the adapter, use one hand on each to avoid damaging the ground terminal. Avoid frequently unplugging the power cord as this can lead to eventual ground terminal damage.

▲ WARNING

- Never use the appliance with a broken adapter.

Temporary Use of an Extension Cord

We strongly discourage the use of an extension cord due to potential safety hazards.

▲ WARNING

This appliance should be installed in accordance with national wiring regulations. This manual acts as a guide to explain the product features.

Maintenance and Service

CAUTION

Before performing any maintenance, turn off the main power to the system, disconnect the circuit breaker and unplug the power cord.

Indoor Unit

Clean the unit with a soft dry cloth. Do not use bleach or abrasives.

▲ WARNING

For inner cleaning, contact an Authorized Service Center or a dealer.

Do not use harsh detergent that causes corrosion or damage on the unit.

- Harsh detergent may also cause failure of product, fire, or electronic shock.

CAUTION

Never use any of these

• Water hotter than 40^ C . It may cause deformation and discoloration.
• Volatile substances. They may damage the surface of the air conditioner.

Air Filters

The air filters behind the front panel / grill should be checked and cleaned once in every 2 weeks or more often if necessary. To remove the filters see the self explanatory diagrams for each model type. Clean the filters with a vacuum cleaner or warm soapy water. If dirt is not easily removed, wash with a solution of detergent in luke warm water. Dry well in shade after washing and reinstall the filters back in place.

mic shock.

Removal of Filters

Open the front panel as shown.

Then pull the filter tab slightly forward to remove the air filter.

Plasma Filter / Allergy Filter Triple Filter

Outdoor Unit

The heat exchanger coils and panel vents of the outdoor unit should be checked regularly. If clogged with dirt or soot, the heat exchanger and panel vents may be professionally steam cleaned.

NOTE

Dirty or clogged coils will reduce the operating efficiency of the system and cause higher operating costs.

Operation Tips!

Do not overcool the room.

This is not good for the health and wastes electricity.

Keep blinds or curtains closed.

Do not let direct sunshine enter the room when the air conditioner is in operation.

Keep the room temperature uniform.

Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.

Make sure that the doors and windows are shut thight.

Avoid opening doors and windows as much as possible to keep the cool air in the room.

Clean the air filter regularly.

Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.

Ventilate the room occasionally.

Since windows are kept closed, it is a good idea to open them and ventilate the room now and ten.

Use high fan speed for effective and fast cooling.

The unit gives its rated cooling capacity when the fan speed is high.

Self-Diagnosis Function

This unit has an inbuilt error diagnosis capability. Unit LED will blink in case if thermistor fails. Please contact your serviceman/dealer in such a situation

Troubleshooting Tips! Save time and money!

The air conditioner may be operating abnormally when:

Problem		What To DoPossible Cau
Air conditioner does not start	■The air conditioner is unplugged.	·Make sure the air conditioner plug is pushed completely into the outlet.
	■The fuse is blown/circuit breaker is tripped.	·Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.
	■Power failure.	·If power failure occurs, turn the mode control to OFF.When power is restored, wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload.
	■High or low voltage.	·If the voltage is unusually very high or low the circuit Breaker will trip.
Air conditioner does not cool as it should	■Airflow is restricted.	·Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner.
	■The air filter is dirty.	·Clean the filter at least every 2 weeks.See the Maintenance and Service section.
	■The room may have been hot.	·When the air conditioner is first turned on, you need to allow time for the room to cool down.
	■Cold air is escaping.	·Check for open furnace floor registers and cold air returns.
	■Check the temperature settings.	·Make sure they are correct.
	■There might be any heating source in the room.	·Check and remove such source or turn it off while using the air conditioner.

Call the service immediately in the following situations

1. Anything abnormal such as burning smell, loud noise etc. happen. Stop the unit and turn the breaker off. Never try to repair by yourself or restart the system in such cases.
2. Main power cord is too hot or damaged.
3. Error code is generated by self diagnosis.
4. Water leaks from indoor unit even if the humidity is low.
5. Any switch, breaker (safety, earth) or fuse fails to work properly

User must carry routine checkup & cleaning to avoid unit's poor performance. In case of special situation, the job must be carried out by service person only. ELECTRICAL SPECIFICATIONS:

220 V \~ 50/60 Hz Since this manual refers to different models, you are invited to pay special attention to the sticker placed on your product to check the consumption of your model.
