PERFORMANCE CURVES7

The standard data contained in these specifications apply only to the operation of the air conditioner under normal conditions.

Since operating conditions vary according to the areas where these units are installed. The following information has been provided to clarify the operating characteristics of the air conditioner under the conditions indicated by the performance curve.

(1) GUARANTEED VOLTAGE

Rated voltage : ±10% (198 ~ 242V ),50Hz

(2) AIR FLOW

Air flow should be set at MAX.

(3) MAIN READINGS

(1) Indoor intake air wet-bulb temperature ::WB (2) Indoor discharge air wet-bulb temperature ::WB (3) Outdoor intake air dry-bulb temperature ::DB (4) Total input :W (5) Indoor intake air dry-bulb temperature ::DB (6) Outdoor intake air wet-bulb temperature ::WB (7) Total input :W

Indoor air wet-bulb temperature difference on the left side of the chart on next page shows the difference between the indoor intake air wet-bulb temperature and the indoor discharge air wet-bulb temperature for your reference at service.

How to measure the indoor air wet-bulb temperature difference

1. Attach at least 2 sets of wet-and dry-bulb thermometers to the indoor air intake as shown in the figure, and at least 2 sets of wet-and dry-bulb thermometers to the indoor air outlet. The thermometers must be attached to the position where air speed is high.

2. Attach at least 2 sets of dry-bulb thermometers to the outdoor air intake. Cover the thermometers to prevent direct rays of the sun.

3. Check that the air filter is cleaned.

4. Open windows and doors of room.

5. Press the EMERGENCY OPERATION switch once (twice) to start the EMERGENCY COOL (HEAT) MODE.

6. When system stabilizes after more than 15 minutes, measure temperature and take an average temperature.

7. 10 minutes later, measure temperature again and check that the temperature does not change.

How to operate with fixed operational frequency of the compressor.

1. Press the EMERGENCY OPERATION switch on the front of the indoor unit , and select either the COOLmode or the HEAT mode before starting to operate the air conditioner.

2. The compressor starts up. The operational frequency of the compressor is 82Hz in the COOL mode and 58Hz in the HEAT mode.

3. The fan speed of the indoor unit is Hi.

4. This operation continues for 30minutes.

5. In order to release this operation, press the EMERGENCY OPERATION switch again, press any button on the remote

controller.

NOTE : The unit of pressure has been changed to MPa on the international system of units(SI unit system).

The conversion factor is: 1(MPa • G) =10.2(kgf/ff• G)

GREEN SIGN

GREEN SIGN shows the current room temperature and set temperature. The room temperature indicated on the temperature monitor lamp may not be exactly the same as the actual room temperature.

Available the set temperature range is 16:~31:, however, indication range of temperature monitor lamp is 21:~30:.

The set temperature (lighting) and room temperature (blinking) are displayed.

When the room temperature or set temperature is out of the indication range

If the set temperature is lower than 21:, indicating lamp at 21: is lighting. And if the room temperature is lower than 21:, indicating lamp at 21: is blinking.

If the set temperature is higher than 30:, indicating lamp at 30: is lighting. And if the room temperature is higher than 30:, indicating lamp at 30: is blinking.

(Example) When the set temperature is 28:, indicating lamp at 28:

2.When the room temperature or set temperature is within the indication range

(Example) When the set temperature is 26:, indicating lamp at 26:

w When the set temperature and room temperature are the same, corresponding indicating lamp is lighting.

NOTE: When the unit is not operating : Both POWER MONITOR lamp and green sign lamps are off. When ON- Timer is set : POWER MONITOR lamp is on. All green sign lamps are off. When OFF- Timer is set : The lamp indication is as same as ordinary operation.

1. Press OPERATE/STOP button on the remote controller. OPERATION INDICATOR lamp of the indoor unit will turn on with a beep tone.

2. Press OPERATION SELECT button to set “I FEEL CONTROL”( ) Then a beep tone is heard.

3. The operation mode is determined by the initial room temperature at start-up of the operation.

● Once the mode is fixed, the mode will not change by room temperature afterwards.

● Under the ON-TIMER ( ) operation, mode is determined according to the room temperature as the operation

starts.

● When the system is stopped with the OPERATE/STOP button on the remote controller, and restarted within 2 hours in “I

FEEL CONTROL” ( ) mode, the system operates in previous mode automatically regardless of the room temperature.

Example

Previous operation COOL mode of “I FEEL CONTROL”

Restart

COOL mode of “I FEEL CONTROL”

or COOL mode

When the system is restarted after 2 hours, the operation mode is determined by the initial room temperature at start-up

of the operation.

Example

Restart

COOL or DRY or HEAT mode of “I FEEL CONTROL” that determined by initial room temperature start-up of the operation.

4. The initial set temperature is decided by the initial room temperature.

❈1 After the system restarts by the remote controller, the system operates with the previous set temperature regardless

of the initial set temperature The set temperature is calculated by the previous set temperature.
