ENGLISH
• Check that the wiring is not broken off or disconnected.
• Check that the air filter is installed. (Some air conditioners havenʼt air filters.)
• Check that the outdoor unit air outlet or inlet is not blocked.
• The air filter can prevent the dust or other particulate from going inside. In case of blockage of the filter, the working
efficiency of the air conditioner may greatly decrease. Therefore, the filter must be cleaned once two weeks during
long time usage.
• If the air conditioner is positioned in a dust place, the cleaning frequency of the air filter must be increased.
• If the accumulated dust is too heavy to be cleaned, please replace the filter with a new one (replaceable air filter
is an optional fitting).
1. Open the air-in grill.
Push the grill switches toward the middle simultaneously as indicated in sketch A. Then pull down the air-in grill.
Caution: The control box cables, which are originally connected with the main body electrical terminators must be
