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.

A) Pull the front grille by grasping the recesses on the ends.
B) Open the front grille up to the position where it is stopped
with a click sound.
