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.

•This function may not be supported depending on the model.
•The Mosquito Away performance can be di erent depending on the customer’s environment .
IMPORTANT: Long term e ect not tested and mosquitoes may become resistant. Mosquito species used in the test below may di er from the mosquito species of your region. This product is one of the ways to manage mosquitoes and not intended to replace other protective devices against mosquitoes.
Test Details:
Tested by Intertek, Korea, according to LG internal testing method.
•Test conducted, three times at temperature of 27±2°C and humidity of 60±10%
•Test used two chambers size 33m3 and 19m3 connected by a channel made of white sheet,
small chamber assumed to be outside (“outside chamber”) and the large chamber to be inside with the LG air conditioner (“inside chamber”)
•One person is placed inside the inside chamber to attract mosquitoes
•For each test, 50 lab cultured 3-5 days old mosquitoes were released into outside chamber;
number of mosquitoes coming into the inside chamber was counted every 10 minutes for 90 minutes under 2 settings:
-Control setting (low fan on + mosquito repelling ultrasonic on)
-Treatment setting (low fan on + mosquito repelling ultrasonic o )
Test Result:
Found to repel on average 72.5% of Aedes aegypti mosquitoes. Repel rate shows percentage of mosquitoes prevented from entering the inside chamber after 90 minutes of Treatment setting compared to Control setting. Represented average of 72.5% derived from 73.1%, 64.3%, 80.0%.
Results may vary in other settings, including but not limited to temperature, humidity, location, space, mosquito species, number of mosquitoes, number of persons, and operation time.
