AIR CONDITIONER UNIT OPERATION
Dry Mode
• When the air humidity is high, the unit can operate in
dry mode. Press <MODE> button and choose <DRY>.
• If the room temperature is 2°C higher than the set
temperature, the air conditioner will operate under
cooling mode until it reaches within the 2°C range of
difference compared to the set temperature before it
converts to dry mode.
• If the room temperature is within the 2°C range of
difference compared to the set temperature, it will
directly operate under dry mode.
• The unit will operate at LOW speed under dry mode.
Fan Speed And Rated Cooling Capacity
• The rated cooling capacity is provided at the maximum
fan speed.
• The cooling capacity is lower when the unit is operating
at MEDIUM and LOW fan speed.
OPERATING RANGE
Horizontal Air Flow Control
• For more effective air circulation, you can manually
adjust the air discharge grille to the left or right.
• During cool mode operation and dry mode operation,
do not direct the air discharge louver downwards for too
long. If operating continues in this way, condensation
may occur on the louver, thus resulting in drippings.
* Dry mode = Cool mode at low fan
