OPERATING INSTRUCTIONS
How the air conditioner works
AUTO operation
• When the air conditioner is set to AUTO mode, it will
automatically select cooling, heating (cooling/heating
models only), or fan-only operation depending on
what temperature you have selected and the room
temperature.
• The air conditioner will control room temperature
automatically depending on the temperature set by you.
• If the AUTO mode is uncomfortable, you can select
desired conditions manually.
SLEEP operation
When the SLEEP button is pressed on remote controller
during cooling, heating (cooling & heating models only),
or AUTO operation, the air conditioner will automatically
increase (cooling) or decrease (heating) at the rate of 1ºC
per hour for the fi rst 2 hours, then hold steady for the next
5 hours. After that it will switch off. This characteristic saves
energy and maintains comfort levels during night operation.
DRYING operation
• The fan speed will be automatically controlled under dry
operation.
• During the dry operation, if the room temperature is
lower than 10ºC, the compressor stops operation and
restarts once the room temperature rises above 12ºC.
Optimal operation levels
To achieve optimal performance, please note the following;
• Adjust the air fl ow direction correctly so that it is not
directed on people.
• Adjust the temperature to achieve the highest comfort
level. Do not adjust the unit to excessive temperature
levels.
• Close doors and windows on COOL or HEAT modes or
performance may be reduced.
• Use TIMER ON button on the remote controller to select a
time you want to start your air conditioner.
• Do not put any object near the air inlet or outlet, as the
effi ciency of the air conditioner may be reduced and the
air conditioner may stop running.
• Clean the air fi lter periodically, otherwise cooling or
heating performance may be reduced.
• Do not operate unit with horizontal louvre in closed
position.
