General Maintenance
Regular checks, maintenance and care should be performed by professional personnel, which
will prolong the unit life span.
Filter Care
Regular filter cleanings are essential for efficient operation and extending the unit life. Clean
the unit filter every 30-90 days as needed. When the unit is in a dusty environment, the unit
may require more frequent cleaning.
WARNING
1. Turn off the unit and disconnect the main power supply when cleaning the air conditioner,
otherwise electric shock or injury may occur.
2. Do not wash the air conditioner by rinsing with water, otherwise electric shock may occur.
Cleaning the Air Filter
1. Open the air inlet grille. Open the two buckles on the grille as shown in Fig. A below. Remove
the screws under the buckles with a screwdriver, then open the inlet grille.
2. Remove the air filter.
3. Clean the filter. Wash the filter with lukewarm water. If the filter is excessively dirty, a mild
neutral detergent may be used to clean it. Rinse thoroughly and allow to air dry. Note: Do
not clean the filter with hot water above 113°F (45°C). Do not use any chemical cleaning
solvents or dry with a heat source to avoid damage, warping and discoloration.
4. Install the cleaned and dried air filter.
5. Replace the screw under the buckles.
6. Fasten the buckles on the grille to secure the filters.
