1. Precautions
1)Remove power cable from power outlet.
Remove power cable from an outlet prior to disassembly for repair.
When the power cable is removed wait for at least 1 minute and measure the voltage between the + and - terminal of the large capacity electrolyti capacitor using a tester. Make sure that the voltage is less than DC 10V, then starts repairing.
2)Warning about electrical shock
If you cannot avoid checking the circuits with power not disconnected pay special attention not to touch live parts to avoid electric shock.
3)Use proper parts
Use genuine parts of a model if parts need to be replaced. (It is recommended that parts are replaced rather than repaired, to avoid electrical contact. Customers should refrain from repairing parts themselves as this can be extremely dangerous.)
4)Use proper tools
Use proper tools for repair and be familiarized with handling test equipment.
Using worn out tools may result in problems such as intermittent contact, etc.
5)Lead wire or power cable damaged
Check if lead wire or power cord is damaged prior to repair, and replace if damaged.
6)Avoid tapping a power cord
Tapping a power cable or using an extension cord from a power outlet is dangerous and should be avoided. It may result is malfunctioning or fire.
7)Checking insulation
Be sure to check insulation resistance when assembly is completed. (Check insulation resistance between the power
cord plug and ground terminal using an ohm meter and check if it is greater than 30MΩ prior to applying the power.)
8)Check grounding
Check grounding status and fix it if not sufficient.
9)Check installation condition
Check installation condition and fix insufficient conditions. If it is still not satisfactory find another area for installation.
10)Child care
It is recommended to have children stay away the units when the repair is being done to avoid accidents.

Operating Instructions and Installation
3-1-2 Main controller function.
1.AUTO MODE: In this mode, operation mode (COOL) is selected automatically by the room temperature of initial operation.
Operation Type
Cool Operation (Set Temp:24°C + T)
T= -1°, -2°C, 0°C, +1°C, +2°C
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.
The setting temperature range is 18°Cthrough 30°C.
3.DRY MODE: The unit is operated at compressor on state regardless of room temperature for an initial 30 minutes of dehumidification operation, and the indoor fan motor is automatically operated due to the temperature difference between the room temperature and set temperature.
The compressor is automatically controlled due to the temperature difference between room temperature and set temperature after operation of 30 minutes.
*Set temperature: 18°C~30°C
*Protective function: Low temperature release. (Prevention against freeze)
4.TURBO MODE: This mode is available only in AUTO, COOL 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.
5.MILD MODE: This mode is available only in AUTO, COOL mode.
When this button is pressed at first, the air conditioner is operated in its current state for 3 hours.
The setting temperature is automatically raised by 3°C.
When this button is pressed again or when the operating time is 3 hours, mild operation mode is canceled and returned to the previous mode.
6.SLEEP MODE: Sleep mode is available only in COOL mode.
The operation will stop after 6 hours.
*In COOL mode : The setting temperature is automatically raised by 1°C each 1hour When the temperature has been raised by total of 2°C, that temperature is maintained.
7.FAN SPEED: Manual (3 step), Auto (4 step), Natural
Fan speed automatically varies depending on both the difference between setting and the room temperature.
8.COMPULSORY OPERATION:
For operating the air conditioner without the remote controller.
The operating is the same function that AUTO MODE in the remote controller.
*Set temperature: 22°C

9.SWING: BLADE-H is rotated vertically by the stepping motor.
*Memory louve: When ON/OFF button is pressed at stop state, the BLADE-H returns to its original location which is operating state before stop.
*Swing auto: The BLADE-H can rotate within about 35° in the original position set by the SWING SET button.
*Swing set: Press the SWING SET button, then the blade rotates vertically by 8°
The BLADE-H location is dispalyed on REMOTE CONTROL. (total 7 steps)
10.Q.TIMER: Q. timer (quick timer) allows reservation or cancel the timer on and timer off quickly.
When Q.timer button is pressed at operating state, LCD displays the polling state sequentially.
The LCD also displays the time remaining.
11.TIMER: The air conditioner is turned ON/OFF at a specified time using TIMER ON/OFF.
*Timer LED lights on.
Operating Instructions and Installation
12.SELF TEST
*Interruption of electric power and Power on.
*Abnormal condition of the room sensor.
*Indoor unit fan motor lock.
*Abnormal condition of the indoor unit's heat exchanger sensor.
13.TIME SHORTENING: If the "Time short" connector pin is shorted on the main P. C. B, the compressor's three minutes delay function is cancelled, and each operation time is shortened to one fiftieth of its original time.
14.BUZZER SOUND: Whenever the ON/OFF button is pressed or whenever change occurs to the condition which is set up or select, the compulsory operation mode, buzzer is sounded "beep".

3-2 Installation
3-2-1 Selecting Area for Installation
Select an area for installation that is suitable to the customer's needs.
3-2-1(a) Indoor Unit
1.Make sure that you install the indoor unit in an area providing good ventilation. It must not be blocked by an obstacle affecting the airflow near the air inlet and the air outlet.
2.Make sure that you install the indoor unit in an area allowing good air handling and endurance of vibration of the indoor unit.
3.Make sure that you install the indoor unit in an area where there is no source of heat or vapor nearby.
4.Make sure that you install the indoor unit in an area from which hot or cool air is spread evenly in a room.
5.Make sure that you install the indoor unit in an area away from TVs, audio units, cordless phones, fluorescent lighting fixtures and other electrical appliances (at least 1 meter).
6.Make sure that you install the indoor unit in an area which provides easy pipe connection with the outdoor unit, and easy drainage for condensed water.
7.Make sure that you install the indoor unit in an area which is large enough to accomodate the measurements shown in figure on the next page.
3-2-1(b) Outdoor Unit
1.Make sure that you install the outdoor unit in area not exposed to the rain or direct sun light.
(Install a separate sunblind if exposed to direct sun light.)
2.Make sure that you install the outdoor unit in area allowing good air moment, not amplifying noise or vibration, especially to avoid disturbing neighbours.
(Fix the unit firmly if it is mounted in a high place.)
3.Make sure that you install the outdoor unit in area providing good ventilation and which is not dusty. It must not be blocked by any obstacle affecting the airflow near the air inlet and the air outlet.
4.Make sure that you install the outdoor unit in area free from animals or plants.
5.Make sure that you install the outdoor unit in area not blocking the traffic.
6.Make sure that you install the outdoor unit in area easy to drain condensed water from the indoor unit.
7.Make sure that you install the outdoor unit in area which provides easy connection within the maximum allowable length of a coolant pipe (15 meters).
Note
1.Add 10 grams of refrigerant (R-22) for every 1 meter if the pipe length exceeds the standard pipe length of 5 meters.
2.Maintain a height between the indoor and outdoor units of less than 3 meters.
8.Make sure that you install the outdoor unit in an area which is large enough to accommodate the measurements
shown in figure on the next page.
3-2-1(c) Remote Control Unit
1.Make sure that you install the remote control unit in an area free from obstacles such as curtains etc, which may block signals from the remote control unit.
2.Make sure that you install the remote control unit in an area not exposed to
direct sunlight, and where there is no source of heat.
3.Make sure that you install the remote control unit in an area away from TVs, audio units, cordless phones, fluorescent lighting fixtures and other electrical appliances (at least 1 meter).
Caution :
It is harmful to the air conditioner if it is used in the following environments: greasy areas (including areas near machines), salty areas such as coast areas, areas where sulfuric gas is present such as hot spring areas. Contact your dealer for advice.
