Explanation & Check points
• Is the breaker turned on?
• Is the power supply plug connected?
• Is the ON timer set? Page 10
• 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.
• These models are equipped with an auto restart function. When
the main power is turned off without stopping the unit with the
remote controller and is turned on again, the unit starts op-
eration automatically in the same mode as the one set with
the remote controller just before the shutoff of the main power.
Refer to "Auto restart function".
• 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.
• When the outside temperature is low during cooling operation, the fan
operates intermittently to maintain suffi cient cooling capacity.
• During COOL and DRY operations, pipe or pipe connecting sections
are cooled and this causes water to condense.
• Are the batteries exhausted?
• Is the polarity (+, -) of the batteries correct?
• Are any buttons on the remote controller of other electric appliances
being pressed?
