IMPORTANT SAFETY INSTRUCTIONS

WARNING

To reduce the risk of explosion, fire, death, electric shock, injury or scalding to persons when using this product, follow basic precautions, including the following:

Children in the Household

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

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.

••Keep any required ventilation openings clear of obstruction.

••Means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.

••Do not install the unit in potentially explosive atmospheres.

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.

••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.

••Do not cut or remove the grounding prong from the power plug.

••Attaching the earth wire to the power outlet cover screw does not ground the appliance unless the cover screw is metal, uninsulated, and the power outlet is grounded through house wiring.

••If you have any doubt whether the air conditioner is properly grounded, have the power outlet and circuit checked by a qualified electrician.

••The refrigerant and insulation blowing gas used in the appliance require special disposal procedures. Consult a service agent or a similarly qualified person before disposing of them.

••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.
