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.
