Explanation & Check points
• Is the breaker turned on?
• Is the power supply plug connected?
• Is the ON timer set? Page 13
• Are the horizontal vanes installed correctly?
• Are the horizontal vane and the vertical vane installed correctly?
• Is the fan guard deformed?
• This protects the unit according to instructions from the microprocessor.
Please wait.
• The cool air from the unit rapidly cools moisture in the air inside the
room, and it turns into mist.
• This is for the swing operation of the HORIZONTAL VANE to be per-
formed normally.
• When the unit is operated in COOL or DRY mode, if the operation
continues with air blowing down for 0.5 to 1 hour, the direction of the
air fl ow is automatically set to upward position to prevent water from
condensing and dripping.
• Outdoor unit is in defrost.
Since this is completed in max. 10 minutes, please wait. (When the
outside temperature is too low and humidity is too high, frost is formed.)
• Although plastic turns yellow due to the infl uence of some factors such
as ultraviolet light and temperature, this has no effect on the product
functions.
