1. Precautions

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

Operating Instructions and Installation
1. AUTO MODE : In this mode, operation mode(COOL, HEAT, DRY) is selected automatically by the room temperature of initial operation. Room Temp Tr 21C+T 21C +T>Tr Operation Type Cool Operation (Set Temp:AUTO SETTING) Heat Operation (Set Temp : 22C+T) 5. TURBO MODE : This mode is available in AUTO, COOL, HEAT, DRY, FAN MODE. When this button is pressed at first, the air conditioner is operated powerful state for 30 minutes regardless of the set temperature, room temperature. When this button is pressed again, or when the operating time is 30 minutes, turbo operation mode is canceled and returned to the previous mode. *But, if you press the TURBO button in DRY or FAN mode that is changed with AUTO mode automatically. 6. SLEEP MODE : Sleep mode is available only in COOL or HEAT mode. The operation will stop after 6 hours. *In COOL mode : The setting temperature is automatically raised by 1C each 1hour When the temperature has been raised by total of 2C, that temperature is maintained. *In HEAT mode : The setting temperature is automatically droped by 1C each 1hour. When the temperature has been droped by total of 2C, that temperature is maintained. 7. FAN SPEED : Manual (3 step), Auto (4 step) Fan speed automatically varies depending on both the difference between setting and the room temperature. 4. DRY MODE : Has 3 states, each determined by room temperature. The unit operates in DRY mode. *Compressor ON/OFF Time is controlled compulsorily(can not set up the fan speed, always breeze). *Protective function : Low temperature release. (Prevention against freeze)

T= -1, -2C, 0C+1C+2C T is controlled by setting temperature up/down key of remote controller 2. COOL MODE : The unit operates according to the difference between the setting and room temperature. (18C~30C) 3. HEAT MODE : The unit operates according to the difference between the setting and room temperature.(16C~30C) *Prevention against cold wind : For about 3~5 minutes after initial operation, thermo control or de-ice, the indoor fan will either not operate or operate very slowly(510 rpm), then switch to the selected fan speed. This period is to allow the indoor unit's heat-exchanger to prewarm before emitting warm air. *High temperature release function : The outdoor unit for and compressor ON/OFF control for safety operation, when the overheat is heat exchanger of indoor unit. *De-ice : Deicing operation is controlled by indoor unit's heat exchanger temperature and accumulating time of compressor's operation. De-ice end by sensing of the processing time by de-ice Condition.

The hose must NOT slope upw ards.
The end of the drain hose must NOT be placed in water.
Do NOT bend the hose in different directions.
Keep a clearance of at least 5cm between the end of the hose and the ground.
Do NOT place the end of the drain hose in a hollow.
To install the drain hose, proceed as follows. 1. If necessary, connect the 2-metre extension to the drain hose. 2. If you are using the extension, insulate the inside part of the extension drain hose with a shield. 3. Pass the drain hose under the refrigerant piping, taking care to keep the drain hose tight. 4. Pass the drain hose through the hole in the wall, making sure that it is sloping downwards, as shown in the illustrations above.

Shield

The hose will be fixed permanently into position once the whole installation has been tested for gas leaks; refer to page 16 for further details.

6. Stop operation of the air conditioner.
7. Close the cap of each valve. Relocation of the air conditioner Refer to this procedure when the unit is relocated. 1. Carry out the pump down procedure (r efer to the details of 'pump down'). 2. Remove the power cord. 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. At this time, cover the valve of the outdoor unit and the other pipe using a cap or vinyl plug to avoid foreign material entering. 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 locatioon. 8. Remove the mounting plate for the indoor unit and move it to a new location.

6) Loosen four fixing screws to separate the motor.

5. Troubleshooting

5-1 Items to be checked first
1) Is the voltage of the power correct? The input voltage shall be 198-264VAC. The airconditioner may not operate properly if the voltage is out of this range. 2) Is the link cable linking the indoor unit and the outdoor unit linked properly? The indoor unit and the outdoor unit shall be linked by 5 cables. Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables. Otherwise the airconditioner may not operate properly. 3) When a problem occurs due to the contents illustrated in the table below it is a symptom not related to the malfunction of the airconditioner.
Operation of air conditioner
The COOL operation indication LED (Green) blinks when a power plug of the indoor unit is plugged in for the first time. In a COOL operation mode, the compressor does not operate at a room temperature higher than the setting temperature that the IN DOOR 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 a HEAT mode. Timer LED only of the indoor unit 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 operation intermittently in a HEAT mode. The compressor stops intermittently in a COOL mode or DRY mode, and fan speed of the indoor unit decreases.

Explanation

It indicates power is on. The LED stops blinking if the operation ON/OFF button on the remote control unit is pushed. In 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 blew

The speed of the indoor fan is set to LL in DRY mode. Fan speed is 5 steps is selected automatically in AUTO mode. Compressor operation is controlled automatically in DRY depending on the room temperature and humidity. mode
When the unit is turned off while de-ice is activated, the compressor continues operation for up to 9 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 a HEAT mode. The compressor operates in a reverse cycle to remove exterior ice in a HEAT mode, and indoor fan and outdoor fan do not operate intermittently for within 20% of the total heater 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.
4) Indoor unit observes operation condition of the air conditioner, and displays self diagnosis details on the display panel.
