1. Precautions
1-1 Precautions for the Service
OUse the correct parts when changing the electric parts.
– Please check the labels and notices for the model name, proper voltage, and proper current for the electric parts.
OFully repair the connection for the types of harness when repairing the product after breakdown.
– A faulty connection can cause irregular noise and problems.
OWhen disassembling or assembling, make sure that the product is laid down on a work cloth.
– Doing so will prevent scratching to the exterior of the rear side of the product.
OCompletely remove dust or foreign substances on the housing, connection, and inspection parts when performing repairs.
– This can prevent fire hazards for tracking, short, etc.
OPlease tighten the service valve of the outdoor unit and the valve cap of the charging valve as securely as possible by using
a monkey spanner.
OCheck whether the parts are properly and securely assembled after performing repairs.
– These parts should be in the same condition as before the repair.
1-2 Precautions for the Static Electricity and PL
OPlease carefully handle the PCB power terminal during repair and measurement when it is turned on since it is vulnerable
to static electricity.
– Please wear insulation gloves before performing PCB repair and measurement.
OCheck if the place of installation is at least 2m away from electronic appliances such as TV, video players, and stereos.
– This can cause irregular noise or degrade the picture quality.
OPlease make sure the customer does not directly repair the product.
– Arbitrary dismantling may result in electric shock or fire.
1-3 Precautions for the Safety
ODo not pull or touch the power plug or the subsidiary power switch with wet hands.
– This may result in electric shock or fire.
OIf the power line or the power plug is damaged, then it must be changed since this is a hazard.
ODo not bend the wire too much or position it so that it can be damaged by a heavy object on top.
– This may result in electric shock or fire.
OThe use of multiple electric outlets should be prohibited.
– This may result in electric shock or fire.
OGround the connection if it is necessary.
– The connection must be grounded if there is any risk of electrical short due to water or moisture.
OUnplug the power or turn off the subsidiary power switch when changing or repairing electrical parts.
– Doing so will prevent electric shock.
OExplain to workers that the battery for the remote control needs to be separated for storage purposes when the product
will not be used for a long time.
– This can cause a problem for the remote control since battery fluid may trickle out.

1-4 Precautions for Handling Refrigerant for Air Conditioner
Environmental Cautions: Air pollution due to gas release
OSafety Cautions
If liquid gas is released, then body parts that come into contact with it may experience frostbite/blister/numbness.
If a large amount of gas is released, then suffocation may occur due to lack of oxygen. If the released gas is heated, then noxious
gas may be produced by combustion.
OContainer Handling Cautions
Do not subject container to physical shock or overheating. (Flowage is possible while moving within the regulated pressure.)
1-5 Precautions for Welding the Air Conditioner Pipe
ODangerous or flammable objects around the pipe must be removed before the welding.
OIf the refrigerant is kept inside the product or the pipe, then remove the refrigerant prior to welding.
If the welding is carried out while the refrigerant is kept inside, the welding cannot be properly performed. This will also produce
noxious gas that is a health hazard. This leakage will also explode with the refrigerant and oil due to an increase in the refrigerant
pressure, posing a danger to workers.
OPlease remove the oxide produced inside the pipe during the welding with nitrogen gas.
Using another gas may cause harm to the product or others.
1-6 Precautions for Additional Supplement of Air Conditioner Refrigerant
OPrecisely calculate the refrigerant by using a scale and S-net, and proceed with the test operation.
Excessive supplement can cause harm to the product since it can cause an inflow of the liquid refrigerant into the compressor.
ODo not heat the refrigerant container for a forced injection.
This may cause harm to the product or others since the refrigerant container may burst.
ODo not operate the product after removing the product safety pressure switch and sensor.
If the product is blocked inside, then this may cause harm to the product or others due to the excess pressure increase of the
refrigerant gas.
1-7 Other Precautions
OThere should be no leakage of the pipes after installation. When withdrawing the refrigerant, the compressor should be
stopped before removing the connecting pipe.
If the compressor is operating while the refrigerant pipe is not correctly connected and the service valve is opened, then
air and other substances can enter the pipe. The interior of the refrigerant cycle may then build up excessive high pressure
resulting in explosion and damage.

t Sump (oil) temperature sensor dislocation error
1. How to diagnose
1) If the Sump temperature right before the start of compressor = Tsump.ini, current compressor's SUMP temp =Tsump. real,
When the difference between Tsump.ini and Tsump.real is an absolute value so that it cannot be more than 2˚C,
In other words, the condition of Tsump.real-Tsump.ini<2˚C has been satisfied for 60 minutes since a compressor started, it is diagnosed as an error.
After 60 minutes of compressor operation, there will be no Sump sensor dislocation detection.
2. How to check
1) Check if a sensor of the relevant compressor has been dislocated in accordance with error code, assemble and correct the error.

7-2 Pump-down Method
7-2-1 Precautions for Pump-down
1. If the pressure is kept low for a long time to completely replenish the refrigerant of the pipe during the pump-down, then the
compressor may be damaged. Therefore, close the valve immediately if the pressure goes below 2kg/cm.g.
2. If the length of the pipe is too long or the outside temperature is too high, then it may not be able to pump down all of the refrigerant.
In this case, use an empty refrigerant container which can be used for recharge to place some of the system refrigerant inside the
container. The pump down can be easily carried out if only the remaining refrigerant is pumped down.
● Please use a rechargeable container for exclusive use when putting the refrigerant in the container.
Accidents such as explosions can happen and result in damage if normal refrigerant containers are used after illegal modification.
7-2-2 For Single Installation of Outdoor Unit (Only One Outdoor Unit Installed)
1. Close the liquid pipe SVC valve.
2. Press the K2 Button on the PCB of the main outdoor unit. (“K7” mark displayed on the outdoor unit PCB LED.)
3. Observe for low pressure by using the K4 button's view mode once the compressor starts operating.
(If the first number of the LED is “4,” then the following three digits represent the low pressure, expressed up to the first decimal
point.)
Example: 41 22 o 4 means the value of the low pressure, and 122 means that the low pressure is 12.2kg/cm,g.
4. If the low pressure goes below around 2kg/cm,g, then immediately close the SVC valve for the gas and finish the pump-down
operation.
(Finish the pump-down operation, press K2 button two more times, or reset the operation by pressing the K3 button once more.)

Main Unit
7-2-3 When Two or More Outdoor Units are Installed
1. Close the gas valves of each sub unit.
2. Press the K2 button of the outdoor unit PCB three times. At this time, K7 will be
displayed on the PCB LED. After pressing the button, wait for about 20~30 minutes
once the main unit compressor starts operating.
3. Close the liquid pipe valves of each sub unit.
4. Close the liquid pipe valves of the main unit, and observe for low pressure as in the case
of a single outdoor unit.
5. Close the gas valve of the main unit if the pressure drops down, and then finish the
pump-down operation mode.

7-3 How to Put Refrigerant in Refrigerant Container
7-3-1 How to put refrigerant in container before pump-down
1. Prepare a rechargeable exclusive refrigerant container, a scale, and a Manifold gauge.
2. Check the amount of refrigerant remaining in the overall system at the time.
3. Connect the refrigerant container to the outdoor unit as shown in the following figure, and operate only about 50% of the total
indoor units in air conditioning mode.
4. Check the high pressure from the Manifold gauge 10 minutes after the air conditioning begins operation.
Reduce the number of indoor units in operation if the high pressure goes above 30kg/cm2,g. to lower the high pressure below
30kg/cm,g.
5. Check that the high pressure goes below 30kg/cm,g, and open the Manifold gauge connected to the liquid pipe, as well as
the refrigerant container valve, so that the refrigerant flows from the liquid pipe to the refrigerant container.
6. Check the changes in the weight of the container using the scale. Once the desired amount of refrigerant is filled up inside the
container, close the valves, and then remove the Manifold gauge.
7. The amount of refrigerant that can be contained inside the container is about 50% of the amount of refrigerant inside the over
all system.
8. Please take extra caution by precisely determining the amount of the refrigerant that can be put in each container so that too
much refrigerant is not contained in the container.
The weight must be measured by using a scale to avoid putting more refrigerant than the amount originally contained in the
container.
