Cleaning the air inlet grille
Preparation:
1.Turn off the air conditioner using the remote control.

Hold the two sides of the air inlet grille and open upwards.
Move the center arm to the left and remove the grille.

4Fit the left and right arms of the air inlet grille to the shafts on the two sides of the air conditioner and push them in completely, and then push in the center arm.
5Check that the center arm has been completely inserted and close the air inlet
grille.
• Push the arrow locations (four) at the bottom of the air inlet grille to check that the grille is completely closed.
NOTE
Cleaning and maintenance of the indoor/outdoor units are strongly recommended for air conditioning systems which are used regularly.
Failure to clean the indoor/outdoor units regularly will result in poor cooling performance, icing, water leakage and even premature compressor failure.
