TIPS FOR SAVING ENERGY
Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:
• Do not cool excessively indoors. 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, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block
the air flow or weaken the cooling / dehumidifying functions.

READ ALL INSTRUCTIONS BEFORE USING THE APPLIANCE.
• Do not place a heater or other heating appliances near the power cable. It may result in fire,
electric shock, or product failure.
• Make sure that the power cord is not pulled or damaged while the air conditioner is operating.
Failure to do so may result in fire, electric shock, or product failure.
• Do not place any objects on the power cord. It may result in electric shock or product failure.
Installation
• Do not install the air conditioner on an unstable surface or where there may be a danger of it falling.
It may result in death, serious injury, or product failure.
• Contact an authorized service center when you install or relocate the air conditioner. Failure to do so
may result in serious injury or product failure.
• 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 the panel and the cover of the control box safely. Failure to do so may result in explosion or
fire.
• Do not install the air conditioner near a place with a danger of explosion or fire. It may result in ex-
plosion or fire.
• Make sure that the pipe and the power cable that connect the indoor unit and the outdoor unit are
not pulled tight when you install the air conditioner. Failure to do so may result in electric shock or
product failure.
• Do not mix air or gas in the system except for the specific refrigerant. If air enters the refrigerant
system, it may result in an excessively high pressure that causes injury or damage to the equipment.
Use
• Be sure to use only those parts which are listed in the svc parts list. Never attempt to modify the
equipment. It may result in death, serious injury, or product failure.
• Do not pull the power cord when you remove the power plug. It may result in death or electric
shock.
• Discard the batteries where there is no danger of fire. Failure to do so may result in explosion or
fire.
• Contact an authorized service center when the air conditioner is submerged into water due to flood-
ing. Failure to do so may result in explosion or fire.
• Only use components that are approved by the manufacturer and do not repair or modify them. Fail-
ure to do so may result in electric shock or product failure.
• Only use the refrigerant specified on the air conditioner label. It may result in explosion or fire.
• Do not allow water to run into the air conditioner. It may result in explosion or fire.
• Do not leave flammable substances such as gasoline, benzene and thinner near the air conditioner.
It may result in explosion or fire.
• Do not use the air conditioner for an extended period of time in a small place without ventilation.
Ventilate the place regularly. Failure to do so may result in explosion or fire.
