Maintenance of Micro Mesh Stainless Filter (continued)
5
Vacuum the dust.
• In the event the micro mesh stainless filter is heavily dirty and the dust cannot
be cleaned with a vacuum cleaner, wash the filter with neutral detergent and
rinse well with water, and then dry the filter in the shade.
6
Attach the micro mesh stainless filter.
• Align the filter with the top face of the indoor unit, and then slide and push it in.
(The shape of the left and right filters is the same.)
• Tighten the left and right filter locks to the indicated direction.
7
Attach the front panel.
1 Insert the shaft of the left arm along the step on the unit into the hole.
2 Securely insert the shaft of the right arm along the step on the unit into the hole.
3 Make sure that the front panel is securely attached, and then close the front panel.
8
Close the front panel.
• Hold and lift up the front panel.
CAUTION
• If the front panel is loose, it may come off and drop.
• When opening the front panel upwards, please do not use excessive force.
If the front panel comes off the device, this may cause it to malfunction.
• When the front panel remains open, be sure to push up the panel support.
9
Turn on the circuit breaker.
CAUTION
• Improper installation of the micro mesh stainless fi lter could result in malfunction. Filter cleaning
operation can not be performed properly and the (CLEAN) indicator blinks.
• Do not operate the air conditioner without the micro mesh stainless fi lter.
Dust goes in the gap of the heat exchanger as well as inside the appliance and may cause unpleasant smell
on the heat exchanger or could result in malfunction.
• Be extra careful not to cut your hand with the fi n of the heat exchanger when removing and
reattaching the micro mesh stainless fi lter.
• Push down the panel support until it clicks.
• Pull it downward.
Push the both ends of the front panel first and
then its center until it clicks.
