Owner's Manual 3

Indoor/outdoor wiring connections must be secured tightly and the cable should be routed properly so that there is no force pulling the cable from the connection terminals. Improper or loose connections can cause heat generation or fire. Be sure to check the refrigerant to the used. Please read the label on the product. Incorrect refrigerant used can prevent the normal operation of the unit. Do not place a heater or other heating appliances near the power cable. There is risk of fire and electric shock. Do not use the product in a tightly closed space for a long time. Perform ventilation regularly. Oxygen deficiency could occur and hence harm your health. Ventilate the product room from time to time when operating it together with a stove, or heating element etc. Oxygen deficiency can occur and hence harm your health. Take care to ensure that nobody especially kids could step on or fall onto the outdoor unit. This could result in personal injury and product damage. Safely dispose off the packing materials. Like screws, nails, batteries, broken things etc after installation or svc and then tear away and thraw away the plastic packaging bags. Children may play with them and cause injury. Don't use a power cord, a plug or a loose socket which is damaged. Otherwise it may cause a fire or electrical shock. Do not allow water to run into electric parts. Install the unit away from water sources. There is risk of fire, failure of the product, or electric shock. Do not open the front grille of the product during operation. (Do not touch the electrostatic filter, if the unit is so equipped.) There is risk of physical injury, electric shock, or product failure. Turn the main power off and unplug the unit when cleaning or repairing the product. There is risk of electric shock. Take care to ensure that power cable could not be pulled out or damaged during operation. There is risk of fire or electric shock. Make sure to check that the power cable plug is not dirty, loose or broken and then only insert the plug completely.

Do not insert hands or other objects through the air inlet or outlet while the product is operating. There are sharp and moving parts that could cause personal injury. Do not tilt the unit when removing or uninstalling it. The condensed water inside can spill.
If the refrigerant gas leaks during the repair, do not touch the leakaing refrigerant gas. The refrigernat gas can cause frostbite (cold burn) If the refrigerant gas leaks during the installation, ventilate the area immediately. Otherwise it can be harmfull for your health.
Do not mix air or gas other than the specified refrigerant used in the system. If air enters the refrigerant system, an excessively high pressure results, causing equipment damage or injury. Replace the all batteries in the remote control with new ones of the same type. Do not mix old and new batteries or different types of batteries. There is risk of fire or product failure.
Dismantling the unit, treatment of the refrigerant oil and eventual parts should be done in accordance with local and national standards.
Do not recharge or disassemble the batteries. Do not dispose off batteries in a fire. They may burn or explode. Do not let the air conditioner run for a long time when the humidity is very high and a door or a window is left open. Moisture may condense and wet or damage furniture. Use a firm stool or ladder when cleaning, maintaining or repairing the product at an height. Be careful and avoid personal injury.
If the liquid from the batteries gets onto your skin or clothes, wash it well with clean water. Do not use the remote if the batteries have leaked. The chemicals in batteries could cause burns or other health hazards. Do not expose your skin or kids or plants to the cool or hot air draft. This could harm to your health.

Owner's Manual 5

Electrical Safety
This appliance must be properly grounded. To minimize the risk of electric shock, you must alway plug into a grounded oulet. 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.
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.
This appliance should be installed in accordance with national wiring regulations. This guide acts as a guide to help to explain product features.

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( Please contact your serviceman/dealer in such a situation Error Display LED ( (once) ) ) will blink in case if thermistor fails.
Check Point Indoor room temperature thermistor open/short. Indoor pipe temperature thermistor open/short.

Troubleshooting Tips! Save time and money!
The air conditioner may be operating abnormally when:
Problem Possible Causes s The air conditioner is unplugged. s The fuse is blown/circuit breaker is tripped. Air conditioner does not start s Power failure. What To Do Make sure the air conditioner plug is pushed completely into the outlet. Check the house fuse/circuit breaker box and replace the fuse or reset the breaker. 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. If the voltage is unusually very high or low the circuit Breaker will trip. Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner. Clean the filter at least every 2 weeks. See the Maintenance and Service section. When the air conditioner is first turned on, you need to allow time for the room to cool down. Check for open furnace floor registers and cold air returns. Make sure they are correct. Check and remove such source or turn it off while using the air conditioner.
s High voltage. s Airflow is restricted.
s The air filter is dirty. Air conditioner does not cool as it should s The room may have been hot.
s Cold air is escaping. s Check the temperature settings. s There might be any heating source in the room.
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 units poor performance. In case of special situation, the job must be carried out by service person only.
