• Air Cooler Body: Before cleaning, ensure that the unit is turned off and unplugged from the
power source. Wipe down the outside with a damp cloth, using only water. Avoid using
harsh chemicals that may cause damage to the unit.
• Filter: The air cooler's filter can get clogged with dust and debris over time. The filter is
located in the back and sides of the fan and should be cleaned regularly. To clean it,
remove the filter and wash it with a mild soap solution. Rinse it thoroughly with clean water
and let it dry completely before replacing it. It is recommended to clean the filter once a
month.
• Eliminate Air Cooler Odors: Evaporative coolers may develop musty odors over time.
To freshen up the portable cooler, add essential oils to the water. Mix 15 drops of scented
essential oil with vinegar and place it in a spray bottle. After cleaning the air cooler, spray
the essential oil mixture into the unit. This will help eliminate any unpleasant odors and
leave a pleasant scent.

E. Check the Mechanical Parts
Check the mechanical parts. While you have the air cooler apart, use a few
drops of lubricating oil on the motor and fan. Use a few drops to lubricate the
parts.
After a long time of use, the fan can be stuck, so it is important to pay attention
to hygiene. When cleaning the fan, use a damp towel to wipe it clean, avoiding
washing directly with water because it may contain the panel and the LED
display. The fan should be cleaned once a month.

Note: When using the air cooler for the first few hours, you may notice a slight odor. This
is normal and should dissipate after a few hours of use. This is due to the materials used
during manufacturing and is not harmful to your health. To reduce the odor, it is recom-
mended to run the air cooler on the highest speed with a full tank of water for a few hours
in a well-ventilated area. After this initial period, the odor should dissipate.
If the problem persists after attempting these solutions, please contact Kolin customer
service for further assistance.
