1. PRE-FILTER
Please clean the Pre-fi lter once about every two weeks. By doing so, the power rates are saved. In case
the Pre-fi lter is full of dust, the air fl ow will decrease and the cooling capacity will be reduced. Further,
noise may occur. Be sure to clean the Pre-fi lter following the procedure below.
Open the front panel and remove the Pre-fi lter
● Gently lift and remove the air purifying fi lters
from the air purifying fi lter frame.
Vacuum dust from the Pre-fi lter and air purifying
fi lter using vacuum cleaner. If there is too much
dust, wipe the fi lter with wet clotch or sponge.
Allow fi lters to dry in shade.
● Re-insert the air purifying fi lter to the fi lter frame.
Set the Pre-fi lter with “FRONT” mark facing front,
and slot them into the original state.
● After attaching the Pre-fi lters, push the front
panel at three arrow portions as shown in
fi gure and close it.
● Do not operate the air conditioner without Pre-fi lter. Dust may enter the air conditioner and fault may
occur.
● Do not wash with hot water at more than 104°F(40°C). The Pre-fi lters may shrink.
● When washing it, shake off moisture completely and dry it in the shade; do not expose it directly to the
sun. The Pre-fi lters may shrink.
● Do not use detergent on the Pre-fi lter as some detergent may deteriorate the Pre-fi lter electrostatic
performance.

● Air purifying fi lter should be cleaned every month or sooner if noticeable loading occurs. When used
overtime, it may lose its deodorizing function. For maximum performance, it is recommended to replace
it every 1 year depending on application requirements.
