4 SAFETY INSTRUCTIONS
Installation
•• Do not install the air conditioner on an unstable surface or in a place where there is danger of it falling.
•• Contact an authorized service center when installing or relocating the air conditioner.
•• Install the panel and the cover of the control box safely.
•• Do not install the air conditioner in a place where flammable liquids or gases such as gasoline, propane, paint thinner, etc., are stored.
•• Make sure that the pipe and the power cable connecting the indoor and outdoor units are not pulled too tight when installing the air conditioner.
•• Use standard circuit breaker and fuse that conform to the rating of the air conditioner.
•• Do not input air or gas into the system except with the specific refrigerant.
•• Use non-flammable gas (nitrogen) to check for leak and to purge air; using compressed air or flammable gas may cause fire or explosion.
•• The indoor/outdoor wiring connections must be secured tightly, and the cable should be routed properly so that there is no force pulling the cable from the connection terminals. Improper or loose connections can cause heat generation or fire.
•• Install dedicated electric outlet and circuit breaker before using the air conditioner.
•• Do not connect the ground wire to a gas pipe, a lightning rod, or a telephone ground wire.
•• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified person in order to avoid a hazard.
Operation
•• Be sure to use only those parts listed in the service parts list. Never attempt to modify the equipment.
•• Make sure that children do not climb on or hit the outdoor unit.
•• Dispose of the batteries in a place where there is no danger of fire.
•• Use only the refrigerant specified on the air conditioner label.
•• Cut off the power supply if there is any noise, smell, or smoke coming from the air conditioner.
•• Do not leave flammable substances such as gasoline, benzene, or thinner near the air conditioner.
•• Contact an authorized service center when the air conditioner is submerged by flood waters.
•• Do not use the air conditioner for an extended period of time in a small place without proper ventilation.
•• In the event of a gas leak (such as Freon, propane gas, LP gas, etc.) ventilate sufficiently before using the air conditioner again.
•• To clean the interior, contact an authorized service center or dealer. Using harsh detergents may cause corrosion or damage to the unit.
SAFETY INSTRUCTIONS 5
•• Be sure to ventilate sufficiently when the air conditioner and a heating appliance such as a heater are used simultaneously.
•• Do not block the inlet or outlet of air flow.
•• Do not insert hands or other objects through the air inlet or outlet while the air conditioner is operating.
•• Make sure that the power cable is neither dirty, loose, nor broken.
•• Never touch, operate, or repair the air conditioner with wet hands.
•• Do not place any objects on the power cable.
•• Do not place a heater or other heating appliances near the power cable.
•• Do not modify or extend the power cable. Scratches or peeling insulation on the power cables may result in fire or electric shock, and should be replaced.
•• Cut off the power supply immediately in the event of a blackout or a thunderstorm.
•• Take care to ensure that power cable could not be pulled out or damaged during operation.
•• Do not touch refrigerant pipe, water pipe and any internal parts while the unit is operating or immediately after operation.
Maintenance
•• Do not clean the appliance by spraying water directly onto the product.
•• Before cleaning or performing maintenance, disconnect the power supply and wait until the fan stops.
CAUTION
To reduce the risk of minor injury to persons, malfunction, or damage to the product or property when using this product, follow basic precautions, including the following:
Installation
•• Do not install the air conditioner in an area where it is directly exposed to sea wind (salt spray).
•• Install the drain hose properly for the smooth drainage of water condensation.
•• Exercise caution when unpacking or installing the air conditioner.
•• Do not touch the leaking refrigerant during installation or repair.
•• Transport the air conditioner with two or more people or use a forklift.
•• Install the outdoor unit such that it is protected from direct sunlight. Do not place the indoor unit in a place where it is directly exposed to sunlight via the windows.
•• Safely dispose of packing materials such as screws, nails or batteries using proper packaging after installation or repair.
•• Install the air conditioner in a place where the noise from the outdoor unit or the exhaust fumes will not inconvenience the neighbors. Failure to do so may result in conflict with the neighbors.

OPERATION
Notes for Operation
Suggestion for Energy Saving
•• Do not over-cool the space. This may be harmful for your health and may consume more electricity.
•• Block sunlight with blinds or curtains while you are operating the air conditioner.
•• Keep doors or windows closed tightly while you are operating the air conditioner.
•• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
•• Speed up the fan to cool or warm indoor air quickly, within a short period of time.
