TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize the power consumption when you use the air conditioner. You can use your air conditioner more efficiently by referring to the instructions below:

• Do not cool excessively indoors. This may be harmful for your health and may consume more electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors and windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool indoor air quickly, in a short period of time.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

BEFORE USE

Preparing for operation

• Contact an installation specialist for installation.
• Use a dedicated circuit.

Usage

• Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for extended period of time.
• Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other heating devices.
• Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices, food, pets, plants, and art objects). Such usage could damage the items.

Cleaning and maintenance

• Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges.
• Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock.
• When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a very high speed during operation. There is a possibility of injury if the unit’s power is accidentally triggered on while cleaning inner parts of the unit.

When the air conditioner is to be used again.

1. Clean the air filter and install it in the indoor unit.
2. Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.

Operation Tips

Do not overcook 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 tight.
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 reduces the airflow and lowers the 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 then.

Troubleshooting Tips!

Save time and money!
Check the following points before requesting repairs or service…. If the malfunction persist, please contact your dealer.

The air conditioner does not operate.
–  Have you made a mistake in timer operation?
–  Has the fuse blown or has the circuit breaker been tripped?| The room has a peculiar odor.
– Check that this is not a damp smell exuded by the walls, carpet, furniture or cloth items in the room.| It seems that condensation is leaking from the air conditioner.
– Condensation occurs when the airflow from the air conditioner cools the warm room air.| Air conditioner does not operate for about 3 minutes when restart.
–  This is the protector of the mechanism.
–  Wait about three minutes and operation will begin.
---|---|---|---
Does not cool effectively.

–  Is the air filter dirty? See air filter cleaning instructions.
–  The room may have been very hot when the room air conditioner was first turned on. Allow time for it to cool down.
–  Has the temperature been set incorrectly?
–  Are the indoor unit’s air inlet or outlet vents obstructed?

| The air conditioner operation is noisy.
–  For a noise that sounds like water flowing.

• This is the sound of Freon flowing inside the air conditioner unit.
  –  For a noise that sounds like the compressed air releasing into atmosphere.
  –  This is the sound of the dehumidifying water being processed inside the air conditioning unit.| Crack sound is heard.
  – This sound is generated by the expansion/constriction of the front panel, etc. due to changes of temperature.| Remote control display is faint, or no display at all.
  –  Are the batteries depleted?
  –  Are the batteries inserted in the opposite (+) and (-) directions?
  The air conditioner changes generated airflow during operation.
  When the air conditioner reaches the desired temperature, the airflow rate reduces in order to avoid generating cool airflow during heating, or to minimize energy consumption and indoor humidity change during cooling.
  – This symptom is normal.| The error code is occurred after lightning struck
  – This product has been applied to the over current protection circuit.
  Error can occur, but it is normal behavior. After few minutes, It will operate normally.

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.
