In

Cool mode, set the appropriate desired temperature.

f If the desired temperature is too low, it may be harmful for human body and power consumption will also increase. Set

the desired temperature about 5 °C lower than the outdoor temperature.

Use extra heating apparatus during heat mode.

f Heating performance of the air conditioner may decrease when the indoor•outdoor temperature drops. Therefore, use

extra heating apparatus. (Applicable model: AF50MS3MCEE✴ Series)

When cooling the room, use air conditioner and fan together to save energy.

f When the air conditioner is used with fan, cooling will be more eective and energy can be saved.

When the air conditioner is operating, close the doors and windows.

f When the air conditioner is used with doors and windows open, cooling/heating eect will decrease.

Basic operation

Basic operation is an operation mode that can be selected by pressing the Mode button.

Auto

In Auto mode, the air conditioner will automatically set theOperation(Cool/Heat Mode) and fan speed depending on the

room temperature detected by the room temperature sensor. (

Heat mode is applicable to AF50MS3MCEE✴ model only.)

Cool

Cool mode is frequently used and you can freely control the temperature, fan speed, and air ow direction in cool mode.

Dry

The air conditioner in Dry mode acts like a dehumidier by removing moisture from the indoor air. The Dry mode will provide

you with fresh air even on a rainy day.

f Outdoor unit will repeatedly and automatically turn on/o for maximum dehumidication according to the temperature

dierence of the current and desired temperature.

Fan

Fan mode can be selected to ventilate your room. Fan mode will be helpful to refresh the stale air in your room.

f If you are not going to use the air conditioner for a while, we recommend to operate the Fan mode for 3~4 hours to dry

the internal part of the air conditioner..

Heat (Applicable model: AF50MS3MCEE✴)

In Heat mode, the indoor temperature, fan speed, and air ow direction can be adjusted at your desire to warm your indoor.

f Indoor unit may not start the operation immediately until indoor heat exchanger is warmed up to a certain temperature

(approximately 5 minutes according to current indoor temperature) to prevent generating a cold breeze.

f Defrost display: When removing frost at the outdoor unit in the Heat mode, (Defrost) icon will be displayed on the indoor

unit display and it will be turned o after removing the frost.

(When removing the frost during the defrost operation in Heat mode, steam may be generated and the warm breeze

may not come out from the indoor unit.)

• When the outdoor temperature is low and humidity is high, frost may form on outdoor unit's heat exchanger

and may decrease the heating performance so the Defrost operation will operate for 5 ~ 12 minutes to get rid of

the frost on the outdoor unit heat exchanger. Indoor unit will be o during Defrost operation is on since cold air

may come out from it.

- Intervals between Defrost operation cycle may vary depending on the amount of frost on the outdoor unit.

- In snowy or rainy days, Defrost operation cycle may be shorter due to humidity.

- You cannot control the air conditioner with the remote controller while Defrost operation is on. Try to control

the air conditioner after Defrost operation is complete.
