Safety Precautions

Use power cables of sufficient current carrying capacity and rating.

• Cables that are too small may leak, generate heat, and cause a fire.

Do not use the product for special purposes, such as preserving foods, works of art, etc. It is a consumer air conditioner, not a precision refrigeration system.

• There is risk of damage or loss of property.

Keep the unit away from children. The heat exchanger is very sharp.

• It can cause the injury, such as cutting the finger. Also the damaged fin may result in degradation of capacity.

When installting the unit in a hospital, communication station, or similar place, provide sufficient protection against noise.

•

The inverter equipment, private power generator, high-frequency medical equipment, or radio communication equipment may cause the air conditioner to operate erroneously, or fail to operate. On the other hand, the air conditioner may affect such equipment by creating noise that disturbs medical treatment or image broadcasting.

Do not install the product where it is exposed to sea wind (salt spray) directly.

• It may cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient operation.

Safety Precautions

■ Operation

Do not use the air conditioner in special environments.

• Oil, steam, sulfuric smoke, etc. can significantly reduce the performance of the air conditioner or damage its parts.

Do not block the inlet or outlet.

• It may cause failure of appliance or accident.

Make the connections securely so that the outside force of the cablemay not be applied to the terminals.

• Inadequate connection and fastening may generate heat and cause a fire.

Be sure the installation area does not deteriorate with age.

• If the base collapses, the air conditioner could fall with it, causing property damage, product failure, or personal injury.

Install and insulate the drain hose to ensure that water is drained away properly based on the installation manual.

• A bad connection may cause water leakage.

Be very careful about product transportation.

• Only one person should not carry the product if it weighs more than 20 kg.

• Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous.

• Do not touch the heat exchanger fins. Doing so may cut your fingers.

• When transporting the Outdoor Unit, suspending it at the specified positions on the unit base. Also support the Outdoor Unit at four points so that it cannot slip sideways.

Safety Precautions

Safely dispose of the packing materials.

•

Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.

•

Tear apart and throw away plastic packaging bags so that children may not play with them. If children play with a plastic bag which was not torn apart, they face the risk of suffocation.

Turn on the power at least 12 hours before starting operation.(In case of outdoor temperature 5°C below)

• Starting operation immediately after turning on the main power switch can result in severe damage to internal parts. Keep the power switch turned on during the operational season.

Do not touch any of the refrigerant piping during and after operation.

• It can cause a burn or frostbite.

Do not operate the air conditioner with the panels or guards removed.

• Rotating, hot, or high-voltage parts can cause injuries.

Do not directly turn off the main power switch after stopping operation.

• Wait at least 5 minutes before turning off the main power switch. Otherwise it may result in water leakage or other problems.

Auto-addressing should be done in condition of connecting the power of all indoor and outdoour units. Auto-addressing should also be done in case of changing the Indoor Unit board(PCB).

Use a firm stool or ladder when cleaning or maintaining the air conditioner.

• Be careful and avoid personal injury.

Do not insert hands or other objects through the air inlet or outlet while the air conditioner is plugged in.

• There are sharp and moving parts that could cause personal injury.

Operation Details

■ Time Delay Safety Control

• 5sec

Vertical louvers are delayed for 5 secs to be opened to prevent the frictional sound between louver and air flow.

• 30sec The 4-way valve is ceased for 30sec. to prevent abnormal noise when the Heating operation is OFF or switched to the other operation mode while compress is off. While compressor is running, it takes 3~5 seconds to switch.

■ Auto Swing Control

• This function is to swing the louver up and down automatically.

■ Air-Filter Checking Control

• 'Filter' sign will appear on the remote controller display and main body display when an air-filter is polluted. Then

clean the air-filter referring to Owners Manual.

■ Soft-Dry Operation

• The indoor fan speed is automatically set to the low, and fan speed control is not available because of already being

set to the best speed for Dry Operation by microcontroller control.

■ Cooling Mode Operation

• When selecting the Cooling( ) Mode Operation, the unit will operate according to the setting by the remote con-

troller and the operation diagram is as follows.
