1. Precautions
1-1 Precautions for the Service
f Use the standard parts when replacing the electric parts.
– Confirm the model name, rated voltage, rated current of the electric parts.
f Repair the disconnection of HARNESS securely when repairing the break down.
– If there is any connection error, it causes an abnormal noise and incorrect operation.
f In case that you assemble or disassemble the products with laying it on the side, do work on the work cloth.
– If not, the exterior of products can be scratched.
f Remove dust and foreign materials from harness, connection part, and inspection part thoroughly when repairing the break down.
– It protects the danger of fire such as tracking and short.
f Tighten tightly the service valve of outdoor unit and the cap of charging valve with a monkey spanner.
f Check the assembly status of parts after repairing the break down.
– It should be same as the status before repairing.
1-2 Precautions for the Static Electricity and PL
f As the PCB power terminal has a weakness for the static electricity, pay attention to it during the repair and measurement.
– Work with insulation gloves during the repair and measurement of PCB.
f Check the distance between the product and the other electronic appliances such as TV, video, and audio. It should be over 2m.
– If not, it causes a bad picture quality or a noise.
f Repairing the products by consumer should be strictly prohibited.
– There is a danger of electric shock or fire due to incorrect disassembly.
1-3 Precautions for the Safety
f Do not pull any electric wires and do not touch an auxiliary power switch with a wet hand.
– There is a danger of electric shock or fire.
f In case any wire or power plug has been damaged, replace it to eliminate any possible danger.
f Do not bend the power cord by force and do not put any heavy object on the power cord.
– There is a danger of electric shock or fire.
f Do not use multi socket.
– There is a danger of electric shock or fire.
f Ground the product if necessary.
– Be sure to ground the product if there is any danger of electric leakage due to water or moisture.
f Be sure to turn off the auxiliary power switch or pull out the power plug during replacement or repair of electric parts.
– There is a danger of electric shock.
f In case the product will not be in use for a long time, the battery of remote control should be kept separately.
– Leakage of inside fluid can cause break down of remote control.
1-4 Others
f Never store or load the air conditioner upside down or sideways to prevent the damage to the compressor.
f Young children or infirm persons should be always supervised when they use the air conditioner.
f Max current is measured according to IEC standard for safety.
f Current is measured according to ISO standard for energy efficiency.
f When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first before removing the
connection pipe. If the refrigerant pipe is not properly connected and the compressor works with the service valve open, the pipe
inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high. It may cause explosion and injury.
f Pump Down Procedure (When removing the product)
- Turn on the air conditioner and select Cool mode to run the compressor for 3 minutes.
- Release the valve caps on High and Low pressure side.
- Use L wrench to close the valve on the high pressure side.
- Approximately 2 minutes after, close the valve on the low pressure side.
- Stop operation of the air conditioner.
- Disconnect the pipes.

4-4 Items 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 not
operate 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 not
operate 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 automatically in 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
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
C702-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. Don’t 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. Don’t pull the lead wire but hold the whole housing to disconnect or connect a housing from or to the PCB.

7. Preference Sheet
7-1 Refrigerating Cycle Diagram
Indoor Unit
Outdoor Unit
Ê CONDENSER
High temperature and high pressure gas state coolant discharged from the compressor is converted to a liquid state as it
is cooled down by the heat emission in the outdoor condenser unit, and sent to the evaporator.
Ê COMPRESSOR
Low temperature and low pressure coolant is compressed and sent to the cycling system.
ÊEVAPORATOR
Liquid coolant sucked in through the capillary tubes cools down the room by absorbing the surrounding
heat as it evaporates (converting from liquid to gas). (Absorbing heat required for evaporation)
ÊSERVICE VALVE
You can open the valve by turning the need valve counterclockwise using hex wrench, and it is used for vacuum, gas
purging, coolant injection, coolant purging, and indoor-outdoor unit connection.
ÊACCUMULATOR
Accumulator prevents the flow of liquid-state coolant into the compressor. (Liquid-state coolant flowing into the compressor will overload the compressor.)
