1. Precautions
1-1 Precautions for the Service
Use the standard parts when replacing the electric parts. Confirm the model name, rated voltage, rated current of the electric parts.
When repairing the equipment, connection of the harness parts must be firm and solid. A loose connection may cause noise or other malfunction.
When assembling and disassembling the equipment while it is laid down, lay it on soft cloth. Otherwise it may scratch the back of the exterior of the product.
Remove dust or dirt completely from the housing block, wiring block and service parts during repair. This helps prevent the danger of fire caused by tracking or short circuit.
Fasten the valve caps of service valves and charging valves of outdoor unit as much as possible using adjustable wrenches.
Check the status of the components assembly after repair service. The status must be the same as before the repair service.
1-2 Precautions related to static electricity and PL
The PCB power supply block is susceptible to static electricity. Therefore, care must be taken during repair or measuring while the power is on.
Wear insulation gloves for PCB repair or measuring.
Check whether the installation location is at least two meters away from other electronic products such as TV, video, or audio.
Otherwise, the video quality might be degraded or noise might be generated.
Do not let end users repair the products themselves. Unauthorized disassembly might cause electric shock or fire.

1-3 Precautions related to product safety
Do not pull the power cord and do not touch the power plug or aux power switch with wet hands. It might cause electric shock or fire.
A damaged power line or power plug must be replaced to prevent danger.
Do not bend the power cable with excessive force, and do not place a heavy weight on the case as it might damage the cable.
It might cause electric shock or fire.
Do not use multiple electric outlets. This might cause electric shock or fire.
Connect the ground terminal when necessary. You must connect the ground terminal if you determine that there is a danger of electric leakage due to moisture or water.
Unplug the power cable or turn off the auxiliary power switch for electric part replacement and repair service. Otherwise it might cause electric shock.
Instruct end users to separate the batteries from the remote controllers and store them separately when the product is not used for long time.
Otherwise leakage from the dry cell may cause problems with the remote controller.
1-4 Other precautions
The pipes should have no leaks during installation, and the compressor must be stopped before removing connecting pipes for pump down work. Operating the compressor while the service valve is open and coolant pipe is not properly
connected may cause explosion or injury due to abnormal high pressure created inside the coolant cycle as the air can be
absorbed through the pipe.
Pump Down work procedure (When uninstalling the product) Turn on the air conditioner, select cooling operation, and run the compressor for more than three minutes.
Release the high pressure and low pressure valve caps.
Close the high pressure valve completely using an L-wrench
After about two minutes, close the low pressure valve completely.
Stop running the air conditioner.
Separate the connecting pipe.

4-4 Iterms to be checked first
1. The input voltage should be rating voltage 10% range. The air conditioner 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 4 cables. Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables. Otherwise the air conditioner 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 air conditioner.
No Operation of air conditioner Explanation
1 In a COOL operation mode, the compressor does notoperate at a room temperature higher than the setting temperature that the INDOOR FAN should operate.[In case of heat pump model]In a HEAT operation mode, the compressor does notoperate at a room temperature lower than the setting temperature that indoor fan should operate.
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.
2 Compressor stops operation intermittently in DRY( ) mode.
Compressor operation is controlled automaticallyin DRY mode depending on the room temperature and humidity.
3 [In case of heat pump model] Compressor of the outdoor unit is operating although it is turned off in a HEAT mode.
When the unit is turned off while de-ice is activated, the compressor continues operation for up to 12 minutes(maximum) until the deice is completed.
4 [In case of heat pump model]The compressor and indoor fan stop intermittently in HEAT mode.
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.
5 [In case of heat pump model]Indoor fan and outdoor fan stop operation intermittently 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.

4-6 PCB Inspection Method
4-6-1 Pre-inspection Notices
4-6-2 Inspection Procedure
4-6-3 Indoor Detailed Inspection Procedure
1. Turn off the breaker, AC power source, before disassembling the unit because of electrical hazard. 2. Confirm the complete discharge of capacitor C102, C702, C703, C704, C705, C706, C707 on the INVERTER PCB when you touch the PCB. Especially dischargeing speed of C702-C707 is very slow because of little load in stand-by condition. To confirm the voltae of 702-C707, measure the DC link voltage at the IGBT module pins near C701 at which applying voltage (450-510Vdc) is marked. To confirm discharging of C102, measure the voltage of non mounted C103 solder hole or check if all LEDs are off. 3. Dont touch the metal body of electrolytic capacitor for avoiding electrical shock before confirming discharge. 4. To discharging the capacitor use power resistor of about 1 Kohm 10W. Soldering tool(non electronic temperature control type) can be used as a discharging resistor. 5. Dont pull the lead wire but hold the whole housing to disconnect or connect a housing from or to the PCB.
1. Check the connection of each housing to the connector first and the peeling of PCB copper pattern. 2. The PCB is composed of the 3 part in the indoor unit.
INDOOR Main PCB part : Indoor unit control, MICOM and surrounding circuit, relay, fan motor driving circuit, sensor reading circuit, buzzer driving circuit and DC power supplying circuit.
Display PCB part : LED lamps, Switch,Remocon module. INDOOR EMI PCB part : Line filter, Noise Capacitor and Varistor 3. The PCB is composed of the 3 part in the outdoor unit.
EMI PCB part : Line filter for electrical noise, Varistors for surge and Fuses. MAIN PCB part : Refrigeration cycle controller with MICOM INVERTER PCB part : Compressor driving inverter and BLDC fan controller
