1. Precautions
1-1 Precautions for the Service
O Use the standard parts when replacing the electric parts.
– Confirm the model name, rated voltage, rated current of the electric parts.
O When repairing the equipment, connection of the harness parts must be firm and solid.
– A loose connection may cause noise or other malfunction.
O 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.
O 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.
O Fasten the valve caps of service valves and charging valves of outdoor unit as much as possible using adjustable wrenches.
O 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
O 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.
O 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.
O Do not let end users repair the products themselves. – Unauthorized disassembly might cause electric shock or fire.
1-2
1-3 Precautions related to product safety
O 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.
O A damaged power line or power plug must be replaced to prevent danger.
O 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.
O Do not use multiple electric outlets.
– This might cause electric shock or fire.
O Connect the ground terminal when necessary.
– Y ou must connect the ground terminal if you determine that there is a danger of electric
leakage due to moisture or water.
O Unplug the power cable or turn off the auxiliary power switch for electric part
replacement and repair service.
– Otherwise it might cause electric shock.
O 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
O 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.
O 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.

□ 360 Cassette
□ Differentiated innovation air cooling
It delivers a cool air evenly with the circular air current and provides a wide and agreeable cooling area than general ceiling air conditioners.
□ Refreshing and soft wind
It provides a horizontal air current that form natural convection instead of unpleasant direct wind. It is consumer-friendly product that prevents the sudden effective temperature tumble.
□ High quality circular design
It applied the wind direction control technology (Coanda effect) which uses the booster fan. Epoch-making circular design that eliminates the blade.
□ Eco-friendly air conditioner
It is eco-friendly air conditioner that is certified a RoHS technology as well as realize high effectiveness, low noise, super power saving.
□ Electricity savings through S- Inverter System
Apply S-inverter system that change capacity to 10~160% according to circumstance by one compressor and reduce optimum cooling effect and unnecessary electricity consumption.
□ Clearness function of four seasons high efficiency
Energy consumption and driving noise decrease more because can operate clearness function separately. Make healthy and clean environment by bacillus exclusion function and active oxygen neutralization function that virus doctor at air conditioner driving removes air various hazardous substances operating always..
