SAFETY PRECAUTIONS

The following safety precautions must be taken when using your air conditioner.

1. Warning: Prior to repair, disconnect the power cord.

2. Use proper parts: use only exact replacement parts. (Also, we recommend replacing parts rather than repairing them.)

3. Use the proper tools: use the proper tools and test equipment, and know how to use them. Using defective tools or test equipment may cause problems later-intermittent contact, for example.

4. Power cord: prior to repair, check the power cord and replace it if necessary.

5. Avoid using an extension cord, and avoid tapping into a power cord. This practice may result in malfunction or fire.

6. After completing repairs and reassembly, check the insulation resistance.

Procedure: prior to applying power, measure the resistance between the power cord and the ground terminal. The resistance must be greater than 30 megohms.

7. Make sure that the grounds are adequate.

8. Make sure that the installation conditions are satisfactory. Relocate the unit if necessary.

9. Keep children away from the unit while it is being repaired.

10. Be sure to clean the unit and its surrounding area.

INSTALLATION

Selecting area for installation

Select an area for installation that is suitable to the customer’s needs.

1

Location of indoor unit

Keep the air inlet and outlet at a far distance from the blockage.

Keep the height distance between the indoor and outdoor unit at most 5m.

Mount on the wall solid enough to bear the weight of the unit and not cause any shake.

Avoid direct sunshine.

A place easy for condensate drain and easy for connecting with the outdoor unit.

Keep a far distance away from the fluorescent lamp, it may influence the operation of remote controller.

Keep at least 1m away from the TV radio and other home appliances.

2

Location of outdoor unit

A place solid enough to bear the weight of the unit and not cause any shake.

Good ventilation, less dust, far from direct rain and sunshine.

A place where the air discharged out of the outdoor unit or the operation noise will not annoy your neighbours.

No blockage near the outdoor unit.

Caution:

It is harmful to the air conditioner if it is used in the following environments: greasy areas (including area near machines). Salty area such as coastal areas, areas where sulfuric gas is present such as hot spring areas. Contact your dealer for advice.

The power wire and signal wire between the indoor/outdoor units must be connected one by one as per corresponding number on the wiring terminal board.

The connecting cables must be clipped together.

Special cable must be used to connect indoor unit and outdoor unit. It should be ensured

that the terminals are not influenced by external force. Poor connection may cause fire.

The electric box cover must be mounted and secured in position, otherwise fire or electrical

shock may occur because of dust or moisture.

3. Disconnect the assembly cable from the indoor and outdoor units.

4. Remove the flare nut connecting the indoor unit and the pipe.

At this time, cover the pipe of the indoor unit and the other pipe using a cap or vinyl plug to avoid foreign

material entering.

5. Disconnect the pipe connected to the outdoor unit.

6. Make sure you do not bend the connection pipes in the middle and store together with the cables.

7. Move the indoor and outdoor units to a new location.

8. Remove the mounting plate for the indoor unit and move it to a new location.

Operation test

Before test operation, wiring safety inspection must be carried out carefully again.

1. Emergency switch operation: Every press of emergency switch, the air conditioner runs as in the following order:

Cool only type: Cool Shut off

Heat pump type: Cool Heat Shut off

2. Remote controller operation: If the indoor unit sounds like Di, Di when pressing I/O button,

that indicates the air conditioner is under the operation of remote controller. After that, press

every button to test their functions.

3.

Check switch operation: Open the front grille and press the check button. Switch on the power

source and then the operation test is activated. If the indicator lamps light up at first and then

go out in succession or the LED window of the indoor unit illuminates at first and then goes out,

the system is under normal operation. If one of the indicator lamps is flashing at all times, or

failure codes are displayed on the LED window of the indoor unit, the system has something

wrong and please check malfunction immediately.

TROUBLE SHOOTING

Items to be checked first

1. Is the voltage of the power correct?

The input voltage shall be rating voltage 10%.

The air conditioner may not operate properly if the voltage is out of this range.

2. Is the link cable connecting the indoor unit and the outdoor unit linked properly?

Please refer to the “wiring diagram”

Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables.

3. When a problem occurs due to the contents illustrated in the table below, it is symptom not related to the malfunction of the air conditioner.

Operation of air conditioner

In COOL operation mode, the compressor does not operate at a room temperature higher than the setting temperature that the indoor fan should operate.

In a HEAT operation mode, the compressor does not operate at a room temperature lower than the setting temperature that indoor fan should operate.

Fan speed setting is not allowed in AUTO or DRY mode.

Compressor stops operation intermittently in DRY mode.

Compressor of the outdoor unit is operating although it is turned off in HEAT mode.

Timer indicator lamp lights up and the air conditioner does not operate.

The compressor and indoor fan stop intermittently in HEAT mode.

Indoor fan and outdoor fan stop intermittently in HEAT mode.

Explanation

It happens after a delay of 3 minutes when the compressor is reoperated. The same phenomenon occurs when a power is on.

As a phenomenon that the compressor is reoperated after a delay of 3 minutes, the indoor fan is adjusted automatically with reference to a temperature of the air blow.

The speed of the indoor fan is set to low in DRY mode.

Fan speed of 3 steps is selected automatically in AUTO mode.

Compressor operation is automatically controlled in DRY mode depending on the room temperature and humidity.

When the unit is turned off while de-ice is activated, the compressor continues operation for up to 10 minutes(maximum) until the deice is completed.

Timer is being activated and the unit is in ready mode.

The unit operates normally if the timer operation is cancelled.

The compressor and indoor fan stop intermittently if room temperature exceeds a setting temperature in order to protect the compressor from overheated air in HEAT mode.

The compressor operates in a reverse cycle to remove exterior ice in HEAT mode, and indoor fan and outdoor fan do not operate intermittently for within 20% of the total heat operation.

The compressor stops intermittently or the fan speed of the indoor unit decreases to prevent inside/outside air frozen depending on the inside/outside air temperature.

The compressor stops intermittently in COOL mode or DRY mode, and fan speed of the indoor unit decreases.
