Safety precautions

Symbols in this Use and Care Manual are interpreted as shown below.

Be sure not to do.

Grounding is essential.

Pay attention to such a situation.

Warning: Incorrect handling could cause a serious hazard, such as death, serious injury, etc.

Use correct power supply in accordance with the rating plate requirement. Otherwise, serious faults or hazard may occur or a fire maybe break out.

Keep the power supply circuit breaker or plug from dirt. Connect the power supply cord to it firmly and correctly, lest an electric shock or a fire break out due to insufficient contact.

Do not use the power supply circuit breaker or pull off the plug to turn it off during operation. This may cause a fire due to spark, etc.

It is the user's responsibility to make the appliance be grounded according to local codes or ordinances by a licenced technician.

It is harmful to your health if the cool air reaches you for a long time. It is advisable to let the air flow be deflected to all the room

Prevent the air flow from reaching the gas burners and stove.

Protection

♦ Operating condition

The protective device maybe trip and stop the appliance in the cases listed below.

HEATING	Outdoor air temperature is over 24°C
	Outdoor air temperature is below -10°C
	Room temperature is over 27°C

COOLING	Outdoor air temperature is over *43°C
	Room temperature is below 21°C
DRY	Room temperature is below 18°C

*For Tropical (T3) Climate condition models, the temperature point is 55°C instead of 43°C. The temperature of some products is allowed beyond the range. In specific situation, please consult the merchant. If the air conditioner runs in COOLING or DRY mode withdoor or window opened for a long time when relative humidity is above 80%, dew may drip down from the outlet.

- Noise pollution

• Install the air conditioner at a place that can bear its weight in order to operate more quietly.
• Install the outdoor unit at a place where the air discharged and the operation noise would not annoy your neighbors.
- Do not place any obstacles in front of the air outlet of the outdoor unit lest it increases the noise level.

◆ Features of protector

1. The protective device will work at following cases.

2. Restarting the unit at once after operation stops or changing mode during operation, you need to wait for 3 minutes.

3. Connect to power supply and turn on the unit at once, it may start 20 seconds later.

4. If all operation has stopped, press ON/OFF button again to restart, Timer should be set again if it has been canceled.

◆ Features of HEATING mode

Preheat

At the beginning of the HEATING operation, the airflow from the indoor unit is discharged 2-5 minutes later.

Defrost

In HEATING operation the appliance will defrost (de-ice) automatically to raise efficiency.

This procedure usually lasts 2-10 minutes. During defrosting, fans stop operation.

After defrosting completes, it returns to HEATING mode automatically.

Note: Heating is NOT available for cooling only air conditioner models.

Troubleshooting

The following cases may not always be a malfunction, please check it before asking for service.

Trouble Analysis
Does not run		If the protector trip or fuse is blown.Please wait for 3 minutes and start again,protector device may be preventing unit to work.If batteries in the remote controller exhausted.If the plug is not properly plugged.
No cooling or heating air		Is the air filter dirty?Are the intakes and outlets of the air conditioner blocked?Is the temperature set properly?
Ineffective control		If strong interference(from excessive static electricity discharge, power supply voltage abnormality)presents, operation will be abnormal. At this time, disconnect from the power supply and connect back 2-3 seconds later.
Does not operate immediately		Changing mode during operation, 3 minutes will delay.
Peculiar odor		This odor may come from another source such as furniture, cigarette etc, which is sucked in the unit and blows out with the air.
A sound of flowing water		Caused by the flow of refrigerant in the air conditioner, not a trouble.Defrosting sound in heating mode.
Cracking sound is heard		The sound may be generated by the expansion or contraction of the front panel due to change of temperature.
Spray mist from the outlet		Mist appears when the room air becomes very cold because of cool air discharged from indoor unit during COOLING or DRY operation mode.
The compressor indicator(red) lights on constantly, and indoor fan stops.		The unit is shifting from heating mode to defrost. The indicator will lights off within ten minutes and returns to heating mode.

4. Connecting of the Cable

- Indoor Unit

Connect the power cord to the indoor unit by connecting the wires to the terminals on the control board individually in accordance with the outdoor unit connection.

Note: For some models, it is necessary to remove the cabinet to connect to the indoor unit terminal.

- Outdoor Unit

1) Remove the access door from the unit by loosening the screw. Connect the wires to the terminals on the control board individually as follows.
2) Secure the power cord onto the control board with cable clamp.
3) Reinstall the access door to the original position with the screw.
4) Use a recognized circuit breaker for 24K model between the power source and the unit. A disconnecting device to adequately disconnect all supply lines must be fitted.

Front panel Terminal (inside) Cabinet Chassis Indoor unit Access door Terminal(inside) Outdoor unit The figures in this manual are based on the external view of a standard model. Consequently, the shape may differ from that of the air conditioner you have selected.

Caution:

1. Never fail to have an individual power circuit specifically for the air conditioner. As for the method of wiring, refer to the circuit diagram posted on the inside of the access door.
2. Confirm that the cable thickness is as specified in the power source specification.
3. Check the wires and make sure that they are all tightly fastened after cable connection.
4. Be sure to install an earth leakage circuit breaker in wet or moist areas.

Installation instructions

Outdoor unit installation

1. Install Drain Port and Drain Hose (for heat-pump model only)

The condensate drains from the outdoor unit when the unit operates in heating mode. In order not to disturb your neighbor and protect the environment, install a drain port and a drain hose to direct the condensate water. Just install the drain port and rubber washer to the chassis of the outdoor unit, then connect a drain hose to the port as the right figure demonstrates.

Rubber pad (optional) Place under the leg pedestal Washer Drain port Drain hose (prepared by user)

1. Install and Fix Outdoor Unit

Fix with bolts and nuts tightly on a flat and strong floor.

If installed on the wall or roof, make sure to fix the supporter well to prevent it from shaking due to serious vibration or strong wind.

1. Outdoor Unit Piping Connection

2. Remove the valve caps from the 2-way and 3-way valve.

3. Connect the pipes to the 2-way and 3-way valves separately according to the required torque.

4. Outdoor Unit Cable Connection (see previous page)

Air purging

The air which contains moisture remaining in the refrigeration cycle may cause a malfunction on the compressor. After connecting the indoor and outdoor units, release air and moisture from the refrigerant cycle using a vacuum pump, as shown below.

Note: To protect the environment, be sure not to discharge the refrigerant to the air directly.

See next page for air purging steps.

Installation instructions

How to Purge Air Tubes:

(1) Unscrew and remove caps from 2 and 3-way valves.
(2) Unscrew and remove cap from service valve.
(3) Connect vacuum pump flexible hose to the service valve.
(4) Start vacuum pump for 10-15 minutes until reaching a vacuum of 10 mm Hg absolutes.
(5) With vacuum pump still running close the low pressure knob on vacuum pump manifold. Then stop the vacuum pump.
(6) Open 2-way valve, 1/4 turn, then close it after 10 seconds. Check tightness of all joints using liquid soap or an electronic leak detector.
(7) Turn 2 and 3-way valves stem to fully close the valves. Disconnect the flexible vacuum pump hose.
(8) Replace and tighten all valve caps.
