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 equipment may cause problems laterintermittent 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 megaohms.

Fig. 1-1 Avoid Dangerous Contact

Fig. 1-2 No Tapping and No Extension Cords

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.

3-1 Installation

When selecting the area for installing the unit, be sure to obtain approval of the customer.

1. Make sure that you install the unit in an area that provides good ventilation.

The air conditioner must not be blocked by any obstacle affecting the air flow near the air inlet and air outlet.

2. Make sure that you install the unit in an area which can endure the weight and vibration of the unit.

3. Make sure that you install the unit away from heat or vapor.

4. Make sure that you install the unit in an area where the cooled air can be evenly spread in a room.

5. Make sure that you install the unit in an area away from TVs, audio units, cordless phones, fluorescent lighting fixtures and other electrical appliances. (obtain a clearance of at least one meter)

6. Make sure that you install the unit in an area which provides easy drainage for condensed water.

7. Make sure that you install the unit in an area not exposed to rain or direct sunlight. (Install a separate sunblind if exposed to direct sun-

light.)

8. Do not install the unit in an area subjected to noise or vibration amplification which may affect your neighbor. (Fix the unit firmly if mounted in a high place.)

Caution:

Do not use the air conditioner in such areas as a greasy area(including machine oil), saline area(sea side), or sulphuric area(hot spring). When using the air conditioner in these areas, special maintenance is required. Contact your local dealer or our service center for advice.

3-2-1 Cooling operation mode

The compressor is turned on and off according to the ambient temperature and set temperature.

1) Compressor on and off control

• Compressor on and off control according to the ambient temperature The compressor is turned off when "ambient temperature = set temperature

The compressor is turned on when "ambient temperature = set temperature +1˚C"

2) Default value after power reset ➔set temperature = 24˚C (75˚F)

Fan speed = High

3) Set temperature indicating (setting) range : 1˚C(1˚F) interval from 18˚C to 30˚C. (64˚F to 86˚F)

3-2-2 Fan operation mode

1) If "Fan operation mode" signal is received from remocon or panel.

➔ the compressor is immediately turned off and only fan motor is operated at set blowing speed. ➔ it changes such as "High ➔Med ➔ Low ➔ High"(if Fan speed is selected).

2) The initial Fan motor speed is set to "High".

3) The set temperature can not be indicated and set.

3-2-3 Energy saver operation mode

If the compressor turn off at the cooling operation, the fan motor turn off after operation during the fixation time only,

and operation that energy saver by turn off the fixation time only, and operation that energy saver by turn off the motor continuously before the condition of the compressor on. The fan motor is not operated at flow wind operation.

Energy saver operation specification at the cooling operation.

1) Fan motor control in compressor on : operate with setting wind speed

2) Fan motor control in compressor off : After compressor off, the fan motor is operated breeze for 2 minutes and then it turn off.

3) After the fan motor off, the compressor and fan motor is operated normally when the compressor on.

Installation and Operating Instructions

3-2-4 Auto Restart (AW✳✳FB✳EA) : OPTION

1) The operation mode, wind volume of fan motor and the set temperature right before the blackout are memorized in EEPROM and so the operation can continue with the previous operation mode, wind volume of fan motor and the set temperature after the recover of blackout.

3-2-5 Sleep operation mode

1) Enable to sleep operation only when cooling operation.

2) First, 7-SEG LED DISPLAY "SLEEP" while 15 second, Second, 7-SEG LED DISPLAY "8Hr" And, automatically SET OFF after operated while 8 Hour

3) If sleep operation, setting Temperature rise 1˚C after 1 Hour

4) ON TIMER operation, not operation, ENERGY SAVER operation, not sleep operation.

3-2-6 Air flow blade swing motor operation

1) The Air flow blade swing motor is turned on and off according to Air flow blade swing operation in remocon or panel, if SET is cooling or Fan operation mode.

2) If the operation mode is "ENERGY SAVER", in case of fan motor being turned off Air flow blade swing motor is immediately turned off.
