A split air conditioning system is a ductless unit that has a condenser on the outside of the building and an air handling unit on the inside of the building, according to the U.S. Department of Energy. These air conditioning units can save more energy than larger units, because they can cool one room at a time. In some cases up to four air handling units can be connected to one condenser. Fujitsu makes split a/c units that are easy to clean.
Lift up the intake grille and remove it from the Fujitsu split air conditioner. Wipe the grille with a damp cloth.
Remove the air filters from the front of the Fujitsu split air conditioner. Hold the filters by the handles and pull them down. There is one on the left side and one on the right side. Run warm water over the air filters to remove any dust. Set the filters in a shady place to dry completely.
Grab the handle of the dust collection unit, behind the right air filter, and pull it out. Fill a bucket full of warm water and add 1 tsp of mild detergent. Fujitsu recommends low alkalinity or isotope detergent. Place the dust collection unit into the water and let it soak for 10 to 15 minutes. Scrub the dust collection unit with the cloth and rinse it with clean, warm water. Allow it to dry completely in a shady area.
Replace the dust collection unit, the air filters and the grille back in the Fujitsu split air conditioner.
