1. CLEANING AIR FILTERS (ONCE EVERY TWO WEEKS)
Clean the air filters at least once every two weeks to save elec- tricity. Use the vacuum cleaner to remove dust from the air filter.
NOTE: In case the dust on the air filter cannot be easily removed with a vacuum cleaner, use a neutral clean- ing agent. Be sure to sufficiently rinse the air filter with water to completely remove the cleaning agent and allow it to dry in the shade.
