Be sure the Intake Grille (Fig. 4 9) is installed securely. When removing and replacing the air filters, be sure not to touch the heat exchanger, as personal injury may result. CAUTION! Cleaning the Air Filter 1. Open the Intake Grille, and remove the air filter. Lift up the air filter’s handle, disconnect the two lower tabs, and pull out. 2. Remove dust with a vacuum cleaner or by washing. After washing, allow to dry thoroughly in a shaded place. 3. Replace the Air Filter and close the Intake Grille. 1 Align the sides of the air filter with the panel, and push in fully, making sure the two lower tabs are returned properly to their holes in the panel. 2 Close the Intake Grille. (For purposes of example, the illustration shows the unit without Intake Grille installed.) Dust can be cleaned from the air filter either with a vacuum cleaner, or by washing the filter in a solution of mild detergent and warm water. If you wash the filter, be sure to allow it to dry thoroughly in a shady place before reinstalling. If dirt is allowed to accumulate on the air filter, air flow will be reduced, lowering operating efficiency and increasing noise. During periods of normal use, the Air Filters should be cleaned every two weeks. When used for extended periods, the unit may accumulate dirt inside, reducing its performance. We recommend that the unit be inspected regularly, in addition to your own cleaning and care. For more information, consult authorized service personnel. When cleaning the unit’s body, do not use water hotter than 104 °F, harsh abrasive cleansers, or volatile agents like benzene or thinner. Do not expose the unit body to liquid insecticides or hairsprays. When shutting down the unit for one month or more, first allow the fan mode to operate continuously for about one-half day to allow internal parts to dry thoroughly.

WARNING! Make sure the plasma filter unit is properly mounted before cleaning or performing other tasks on it. If the unit is not properly mounted, it could fall off and cause damage or injury. You can be injured if you touch the heat exchanger when removing or installing the plasma filter unit. Do not insert your fingers between the plasma filter unit and the heat exchanger. Before cleaning the plasma filter unit, be sure to turn off the power supply to the air conditioner. Electric shock may result. Regarding the Air Cleaning check function This function is illustrated by the flashing of the AIR CLEAN Indicator Lamp (green), indicating that the unit requires maintenance. After Air Cleaning Mode has been in use for approximately 400 hours, the AIR CLEAN Indicator Lamp (green) will begin to slowly flash (approximately once every 7 seconds). When this occurs, the unit requires maintenance. After Air Cleaning Mode has been in use for approximately 500 hours, the AIR CLEAN Indicator Lamp (green) will begin to flash quickly (approximately once every 3 seconds). At this point, Air Cleaning will cease functioning. Please carry out appropriate maintenance for the unit. Please carry out unit maintenance every 6 months. If a squeaking or chirping sound is heard, unit maintenance needs to be carried out, even if the AIR CLEAN Indicator Lamp (green) is not flashing. Cleaning the dust collection unit 1.
