1. Precautions
1-1 Precautions for the Service
 Use 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.
 Fully repair the connection for the types of harness when repairing the product after breakdown.
– A faulty connection can cause irregular noise and problems.
 When 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.
 Completely remove dust or foreign substances on the housing, connection, and inspection parts when performing repairs.
– This can prevent fire hazards for tracking, short, etc.
 Please 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.
 Check 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
 Please 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.
 Check 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.
 Please 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
 Do not pull or touch the power plug or the subsidiary power switch with wet hands.
– This may result in electric shock or fire.
 If the power line or the power plug is damaged, then it must be changed since this is a hazard.
 Do 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.
 The use of multiple electric outlets should be prohibited.
– This may result in electric shock or fire.
 Ground the connection if it is necessary.
– The connection must be grounded if there is any risk of electrical short due to water or moisture.
 Unplug the power or turn off the subsidiary power switch when changing or repairing electrical parts.
– Doing so will prevent electric shock.
– Although the power is off, Inverter PBA and Fan PBA are dangerous because they are charged with high DC voltage.
– Changing, checking and touching PBA are dangerous because of high DC voltage. So, please turn off the power and wait for
discharging DC voltage. ( To discharging DC voltage naturally, wait for more than 15 minutes.)
 Explain 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
 Safety 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.
 Container 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
 Dangerous or flammable objects around the pipe must be removed before the welding.
 If 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.
 Please 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
 Precisely 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.
 Do not heat the refrigerant container for a forced injection.
This may cause harm to the product or others since the refrigerant container may burst.
 Do 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
 There 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.
