s When installing the air cleansing filters, remove the air filters and attach

them onto the hooks of the front cover frame.

Heating Capability

s This room air conditioner utilizes a heat pump system that absorbs

exterior heat and brings it into a room to be heated. As the ambient
temperature gets lower, heating capability will also lower. In such a
situation, the PAM and inverter work to increase compressor rpm to keep
the unit’s heating

capability from decreasing. If the unit’s heating
performance is still unsatisfactory, other heating appliances should be
used to augment this unit’s performance.

s The air conditioner is designed to heat an entire room so that it may take some time before you feel warm. Timer

operation is recommended for effective preheating ahead

of the desired time.

Cooling and Dehumidifying Capabilities

s If the heat present in a room exceeds the unit’s cooling capacity (for example, if there are many people in the room

or other heating appliances are used), the preset room temperature may not be reached.

INFORMATION

CAPABILITIES

CAUTION

Do not use a stove
or any other high­temperature devices

s When fan speed, room temperature are set with the remote controller before starting manual operation and

the buttons are released, the indication of settings will go off in 10 seconds and only the operation mode will
be displayed.

s Pressing the button while the unit is in operation will let the

protective circuit work so that the unit will

not operate for approximately 3 minutes.

s During heating operation, the indoor unit’s color indicator lamp may flash with no air emitted for a while.

s If you feel cold wind during warming operation with the

(HI) fan speed or want to make the unit operation

quieter after the room is heated, use of

(AUTO) setting is recommended.

s With the

(SILENT) setting, the unit’s cooling capability will lower slightly.

VARIOUS FUNCTIONS

s When the timer has been programmed, the unit will not operate even if the set time is reached unless the unit

receives a signal from the remote controller. Confirm that timer programming is complete (beep) and the
TIMER lamp of the indoor unit lights.
